Implement Pair Class with Unit Class in Java using JavaTuples

Last Updated : 20 Sep, 2018

Following are the ways to implement Pair Class with Unit Class

Using direct values

import java.util.*; 
import org.javatuples.*; 
  
class GfG { 
  
    public static void main(String[] args) 
    { 
        // Create a Unit 
        Unit<String> unit = new Unit<String>("GeeksforGeeks"); 
  
        // print unit 
        System.out.println("Unit: " + unit); 
  
        // create Pair from Unit 
        Pair<Integer, String> 
            pair = new Pair<Integer, String>( 
                Integer.valueOf(1), unit.getValue0()); 
  
        // Print the Pair 
        System.out.println("Pair: " + pair); 
    } 
} 

Output:

Unit: [GeeksforGeeks]
Pair: [1, GeeksforGeeks]

Using Unit.add() method

// Below is a Java program to demonstrate 
// use of add() method with 
// single value 
  
import java.util.*; 
import org.javatuples.*; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Using with() method to instantiate unit object 
        Unit<String> unit = Unit.with("Geeks"); 
  
        // print unit 
        System.out.println("Unit: " + unit); 
  
        // Using add() to create Pair 
        Pair<String, String> pair = unit.add("forGeeks"); 
  
        // Print the Pair 
        System.out.println("Pair: " + pair); 
    } 
} 

Output:

Unit: [Geeks]
Pair: [Geeks, forGeeks]

Using Unit.addAtX() method

Program 1: Adding Unit at Position 0 using addAt0()

// Below is a Java program to demonstrate 
// use of addAt0() method with 
// direct value 
  
import java.util.*; 
import org.javatuples.Unit; 
import org.javatuples.Pair; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Using with() method to instantiate unit object 
        Unit<String> unit = Unit.with("Geeks"); 
  
        // print unit 
        System.out.println("Unit: " + unit); 
  
        // Using addAtX() to create Pair 
        Pair<String, String> pair = unit.addAt0("forGeeks"); 
  
        // Print the Pair 
        System.out.println("Pair: " + pair); 
    } 
} 

Output:

Unit: [Geeks]
Pair: [forGeeks, Geeks]

Program 2: Adding Unit at Position 1 using addAt1()

// Below is a Java program to demonstrate 
// use of addAt1() method with 
// direct value 
  
import java.util.*; 
import org.javatuples.Unit; 
import org.javatuples.Pair; 
  
class GfG { 
    public static void main(String[] args) 
    { 
        // Using with() method to instantiate unit object 
        Unit<String> unit = Unit.with("Geeks"); 
  
        // print unit 
        System.out.println("Unit: " + unit); 
  
        // Using addAtX() to create Pair 
        Pair<String, String> pair = unit.addAt1("forGeeks"); 
  
        // Print the Pair 
        System.out.println("Pair: " + pair); 
    } 
} 

Output:

Unit: [Geeks]
Pair: [Geeks, forGeeks]
