JavaTuples - Quick Guide
JavaTuples - Overview
Tuple
Tuple is a sequence of objects which may or may not be of same type. Consider the following example −
[12,"Howcodex", java.sql.Connection@li757b]
Above object is a tuple of three elements, an Integer, a string and a Connection Object.
JavaTuple
JavaTuples is a very simple library which offers ten different tuple classses which are sufficient to handle most of the tuple related requirements.
Unit<A> - 1 element
Pair<A,B> - 2 elements
Triplet<A,B,C> - 3 elements
Quartet<A,B,C,D> - 4 elements
Quintet<A,B,C,D,E> - 5 elements
Sextet<A,B,C,D,E,F> - 6 elements
Septet<A,B,C,D,E,F,G> - 7 elements
Octet<A,B,C,D,E,F,G,H> - 8 elements
Ennead<A,B,C,D,E,F,G,H,I> - 9 elements
Decade<A,B,C,D,E,F,G,H,I,J> - 10 elements
Apart from these tuple classes, JavaTuples also provides two additional classes for semantics sake.
KeyValue<A,B>
LabelValue<A,B>
All tuple classes are typesafe and immutable and implements following interfaces and methods.
Iterable
Serializable
Comparable<Tuple>
equals()
hashCode()
toString()
Tuple vs List/Array
List or Array can contain any number of elements but each element must be of same type whereas tuples can contain only specific number of elements, can have different type of elements but still are typesafe.
JavaTuples - Environment Setup
Local Environment Setup
If you are still willing to set up your environment for Java programming language, then this section guides you on how to download and set up Java on your machine. Please follow the steps mentioned below to set up the environment.
Java SE is freely available from the link Download Java. So you download a version based on your operating system.
Follow the instructions to download Java and run the .exe to install Java on your machine. Once you have installed Java on your machine, you would need to set environment variables to point to correct installation directories −
Setting up the Path for Windows 2000/XP
We are assuming that you have installed Java in c:\Program Files\java\jdk directory −
Right-click on 'My Computer' and select 'Properties'.
Click on the 'Environment variables' button under the 'Advanced' tab.
Now, alter the 'Path' variable so that it also contains the path to the Java executable. Example, if the path is currently set to 'C:\WINDOWS\SYSTEM32', then change your path to read 'C:\WINDOWS\SYSTEM32;c:\Program Files\java\jdk\bin'.
Setting up the Path for Windows 95/98/M
We are assuming that you have installed Java in c:\Program Files\java\jdk directory −
Setting up the Path for Linux, UNIX, Solaris, FreeBS
Environment variable PATH should be set to point to where the Java binaries have been installed. Refer to your shell documentation if you have trouble doing this.
Example, if you use bash as your shell, then you would add the following line to the end of your '.bashrc: export PATH=/path/to/java:$PATH'
Popular Java Editor
To write your Java programs, you need a text editor. There are many sophisticated IDEs available in the market. But for now, you can consider one of the following −
Notepad − On Windows machine you can use any simple text editor like Notepad (Recommended for this tutorial), TextPad.
Netbeans − It is a Java IDE that is open-source and free which can be downloaded from www.netbeans.org/index.html.
Eclipse − It is also a Java IDE developed by the eclipse open-source community and can be downloaded from www.eclipse.org.

JavaTuples - Create Tuples
A tuple using JavaTuple classes can be created using multiple options. Following are the examples −
Using with() Methods
Each tuple class has a with() method with corresponding parameters. For example −
Pair<String, Integer> pair = Pair.with("Test", Integer.valueOf(5));
Triplet<String, Integer, Double> triplet = Triplet.with("Test", Integer.valueOf(5),
Double.valueOf(32.1));
Using Constructor
Each tuple class has a constructor with corresponding parameters. For example −
Pair<String, Integer> pair = new Pair("Test", Integer.valueOf(5));
Triplet<String, Integer, Double> triplet = new Triplet("Test", Integer.valueOf(5),
Double.valueOf(32.1));
Using Collections
Each tuple class has a fromCollection() method with corresponding parameters. For example −
Pair<String, Integer> pair = Pair.fromCollection(listOfTwoElements);
Using Iterable
Each tuple class has a fromIterable() method to get elements in generic fashion. For example −
// Retrieve three values from an iterable starting at index 5
Triplet<Integer,Integer,Integer> triplet = Triplet.fromIterable(listOfInts, 5);
Example
Let's see JavaTuples in action. Here we'll see how to create tupels using various ways.
Create a java class file named TupleTester in C:\>JavaTuples.
File: TupleTester.java
package com.howcodex;
import java.util.ArrayList;
import java.util.List;
import org.javatuples.Pair;
public class TupleTester {
public static void main(String args[]){
//Create using with() method
Pair<String, Integer> pair = Pair.with("Test", Integer.valueOf(5));
//Create using constructor()
Pair<String, Integer> pair1 = new Pair("Test", Integer.valueOf(5));
List<Integer> listOfInts = new ArrayList<Integer>();
listOfInts.add(1);
listOfInts.add(2);
//Create using fromCollection() method
Pair<Integer, Integer> pair2 = Pair.fromCollection(listOfInts);
listOfInts.add(3);
listOfInts.add(4);
listOfInts.add(5);
listOfInts.add(6);
listOfInts.add(8);
listOfInts.add(9);
listOfInts.add(10);
listOfInts.add(11);
//Create using fromIterable() method
// Retrieve three values from an iterable starting at index 5
Pair<Integer,Integer> pair3 = Pair.fromIterable(listOfInts, 5);
//print all tuples
System.out.println(pair);
System.out.println(pair1);
System.out.println(pair2);
System.out.println(pair3);
}
}
Verify the result
Compile the classes using javac compiler as follows −
C:\JavaTuples>javac -cp javatuples-1.2.jar ./com/howcodex/TupleTester.java
Now run the TupleTester to see the result −
C:\JavaTuples>java -cp .;javatuples-1.2.jar com.howcodex.TupleTester
Output
Verify the Output
[Test, 5]
[Test, 5]
[1, 2]
[6, 8]
JavaTuples - Get Values
A tuple has getValueX() methods to get values and getValue() a generic method to get value by index. For example Triplet class has following methods.
getValue(index) − returns value at index starting from 0.
getValue0() − returns value at index 0.
getValue1() − returns value at index 1.
getValue2() − returns value at index 2.
Feature
getValueX() methods are typesafe and no cast is required, but getValue(index) is generic.
A tuple has getValueX() methods upto element count. For example, Triplet has no getValue3() method but Quartet has.
Semantic Classes KeyValue and LabelValue has getKey()/getValue() and getLabel()/getValue() instead of getValue0()/getValue1() methods.
Example
Let's see JavaTuples in action. Here we'll see how to get values from a tuple using various ways.
Create a java class file named TupleTester in C:\>JavaTuples.
File: TupleTester.java
package com.howcodex;
import org.javatuples.KeyValue;
import org.javatuples.Pair;
public class TupleTester {
public static void main(String args[]){
//Create using with() method

Object value1Obj = pair.getValue(1);
String value0 = pair.getValue0();
Integer value1 = pair.getValue1();
System.out.println(value0Obj);
System.out.println(value1Obj);
System.out.println(value0);
System.out.println(value1);
KeyValue<String, Integer> keyValue = KeyValue.with(
"Test", Integer.valueOf(5)

Changed Pair:[Test, Changed Type]
JavaTuples - Add Elements
A tuple has add() method at the end of a tuple and it changes the type of tuple as well. For example adding a element to Triplet tuple will convert it to a Quartet tuple.
Quartet<String,String,String,String> quartet = triplet.add("Test");
A tuple has addAtX() methods as well to add a position at particular index starting from 0.
Quartet<String,String,String,String> quartet = triplet.addAt1("Test");
A tuple can add more than one elements using addAtX() methods.
Quartet<String,String,String,String> quartet = pair.addAt1("Test1", "Test2");
A tuple can add a tuple as well using addAtX() methods.
Quartet<String,String,String,String> quartet = pair.addAt1(pair1);
Example
Let's see JavaTuples in action. Here we'll see how to add values in a tuple using various ways.

JavaTuples - Remove Elements
A tuple has removeAtX() methods to remove value at particular index. For example Triplet class has following methods.
removeAt0() − remove value at index 0 and return the resulted tuple.
removeAt1() − remove value at index 1 and return the resulted tuple.
removeAt2() − remove value at index 2 and return the resulted tuple.
Removing an element returns a new tuple.

Output
Verify the Output
Triplet:[Test1, 5, Test2]
Pair: [Test1, 5]
JavaTuples - Conversion
Tuple to List/Array
A tuple can be converted to List/Array but at cost of type safety and converted list is of type List<Object>/Object[].
List<Object> list = triplet.toList();
Object[] array = triplet.toArray();
Collection/Array to Tuple
A collection can be converted to tuple using fromCollection() method and array can be converted to tuple using fromArray() method.
Pair<String, Integer> pair = Pair.fromCollection(list);
Quartet<String,String,String,String> quartet = Quartet.fromArray(array);
If size of array/collection is different than that of tuple, then IllegalArgumentException will occur.
Exception in thread "main" java.lang.IllegalArgumentException:
Array must have exactly 4 elements in order to create a Quartet. Size is 5

Each tuple provides utility methods to check their elements in similar fashion as collection.
contains(element) − checks if element is present or not.
containsAll(collection) − checks if elements are present or not.
indexOf(element) − returns the index of first element if present otherwise -1.
lastIndexOf(element) − returns the index of last element if present otherwise -1.
Pair<String, Integer> pair = Pair.with("Test", Integer.valueOf(5));
boolean isPresent = pair.contains("Test");
