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]
