使用 JavaTuples 在Java中使用 Triplet Class 实现 Quartet Class

以下是使用 Triplet Class 实现 Quartet Class 的方法

1. 使用直接值

   import java.util.*;
   import org.javatuples.*;
     
   class GfG {
       public static void main(String[] args)
       {
     
           // create Triplet
           Triplet
               triplet = new Triplet(
                   "Triplet 1", "1", "GeeksforGeeks");
     
           // Print Triplet
           System.out.println("Triplet: " + triplet);
     
           // Create Quartet from Triplet
           Quartet
               quartet = new Quartet(
                   "Quartet 1",
                   triplet.getValue0(),
                   triplet.getValue1(),
                   triplet.getValue2());
     
           // Print Quartet
           System.out.println("Quartet: " + quartet);
       }
   }
   

   输出：

   [Triplet 1, 1, GeeksforGeeks]
   [Quartet 1, Triplet 1, 1, GeeksforGeeks]

2. 使用 Triplet.add() 方法

   import java.util.*;
   import org.javatuples.*;
     
   class GfG {
       public static void main(String[] args)
       {
           // create Triplet
           Triplet
               triplet = new Triplet(
                   "Triplet 1", "1", "GeeksforGeeks");
     
           // Print Triplet
           System.out.println("Triplet: " + triplet);
     
           // Using add() to create Quartet
           Quartet
               quartet = triplet.add("Quartet 1");
     
           // Print Quartet
           System.out.println("Quartet: " + quartet);
       }
   }
   

   输出：

   Triplet: [Triplet 1, 1, GeeksforGeeks]
   Quartet: [Triplet 1, 1, GeeksforGeeks, Quartet 1]

3. 使用 Triplet.addAtX() 方法

   程序 1：使用 addAt0() 在位置 0 添加

   // Below is a Java program to demonstrate
   // use of addAt0() method with
   // direct value
     
   import java.util.*;
   import org.javatuples.*
     
       class GfG {
       public static void main(String[] args)
       {
           /// create Triplet
           Triplet
               triplet = new Triplet(
                   "Triplet 1", "1", "GeeksforGeeks");
     
           // Print Triplet
           System.out.println("Triplet: " + triplet);
     
           // Using add() to create Quartet
           Quartet
               quartet = triplet.addAt0("Quartet 1");
     
           // Print Quartet
           System.out.println("Quartet: " + quartet);
       }
   }
   

   输出：

   Triplet: [Triplet 1, 1, GeeksforGeeks]
   Quartet: [Quartet 1, Triplet 1, 1, GeeksforGeeks]

   程序 2：使用 addAt1() 在位置 1 添加

   // Below is a Java program to demonstrate
   // use of addAt1() method with
   // direct value
     
   import java.util.*;
   import org.javatuples.*;
     
   class GfG {
       public static void main(String[] args)
       {
           // create Triplet
           Triplet
               triplet = new Triplet(
                   "Triplet 1", "1", "GeeksforGeeks");
     
           // Print Triplet
           System.out.println("Triplet: " + triplet);
     
           // Using add() to create Quartet
           Quartet
               quartet = triplet.addAt1("Quartet 1");
     
           // Print Quartet
           System.out.println("Quartet: " + quartet);
       }
   }
   

   输出：

   Triplet: [Triplet 1, 1, GeeksforGeeks]
   Quartet: [Triplet 1, Quartet 1, 1, GeeksforGeeks]

   程序 3：使用 addAt2() 在位置 2 添加

   // Below is a Java program to demonstrate
   // use of addAt2() method with
   // direct value
     
   import java.util.*;
   import org.javatuples.*
     
       class GfG {
       public static void main(String[] args)
       {
           // create Triplet
           Triplet
               triplet = new Triplet(
                   "Triplet 1", "1", "GeeksforGeeks");
     
           // Print Triplet
           System.out.println("Triplet: " + triplet);
     
           // Using add() to create Quartet
           Quartet
               quartet = triplet.addAt2("Quartet 1");
     
           // Print Quartet
           System.out.println("Quartet: " + quartet);
       }
   }
   

   输出：

   Triplet: [Triplet 1, 1, GeeksforGeeks]
   Quartet: [Triplet 1, 1, Quartet 1, GeeksforGeeks]

   程序 4：使用 addAt3() 在位置 3 添加

   // Below is a Java program to demonstrate
   // use of addAt2() method with
   // direct value
     
   import java.util.*;
   import org.javatuples.*
     
       class GfG {
       public static void main(String[] args)
       {
           // create Triplet
           Triplet
               triplet = new Triplet(
                   "Triplet 1", "1", "GeeksforGeeks");
     
           // Print Triplet
           System.out.println("Triplet: " + triplet);
     
           // Using add() to create Quartet
           Quartet
               quartet = triplet.addAt3("Quartet 1");
     
           // Print Quartet
           System.out.println("Quartet: " + quartet);
       }
   }
   

   输出：

   Triplet: [Triplet 1, 1, GeeksforGeeks]
   Quartet: [Triplet 1, 1, GeeksforGeeks, Quartet 1]
