使用JavaTuples在Java中实现五重奏类和四重奏类

以下是实施的方法 五重奏班 具有 四重奏班

1. 使用直接值

   import java.util.*; import org.javatuples.*; class GfG { public static void main(String[] args) { // create Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = new Quintet<String, String, String, String, String>( "Quintet 1" , quartet.getValue0(), quartet.getValue1(), quartet.getValue2(), quartet.getValue3()); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   [Quintet, Triplet 1, 1, GeeksforGeeks]
   [Quintet 1, Quintet, Triplet 1, 1, GeeksforGeeks]

2. 使用四重奏。add（）方法

   import java.util.*; import org.javatuples.*; class GfG { public static void main(String[] args) { // create Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = quartet.add( "Quintet" ); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   Quartet: [Quartet, Triplet, Pair, Unit]
   Quintet: [Quartet, Triplet, Pair, Unit, Quintet]

3. 使用四重奏。addAtX（）方法

   项目1： 使用addAt0（）在位置0处添加

   // 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 Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = quartet.addAt0( "Quintet" ); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   Quartet: [Quartet, Triplet, Pair, Unit]
   Quintet: [Quintet, Quartet, Triplet, Pair, Unit]

   项目2： 使用addAt1（）在位置1处添加

   // 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 Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = quartet.addAt1( "Quintet" ); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   Quartet: [Quartet, Triplet, Pair, Unit]
   Quintet: [Quartet, Quintet, Triplet, Pair, Unit]

   方案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 Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = quartet.addAt2( "Quintet" ); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   Quartet: [Quartet, Triplet, Pair, Unit]
   Quintet: [Quartet, Triplet, Quintet, Pair, Unit]

   方案4： 使用addAt3（）在位置3处添加

   // Below is a Java program to demonstrate // use of addAt3() method with // direct value import java.util.*; import org.javatuples.* class GfG { public static void main(String[] args) { // create Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = quartet.addAt3( "Quintet" ); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   Quartet: [Quartet, Triplet, Pair, Unit]
   Quintet: [Quartet, Triplet, Pair, Quintet, Unit]

   方案5： 使用addAt4（）在位置4添加

   // Below is a Java program to demonstrate // use of addAt4() method with // direct value import java.util.*; import org.javatuples.* class GfG { public static void main(String[] args) { // create Quartet Quartet<String, String, String, String> quartet = new Quartet<String, String, String, String>( "Quartet" , "Triplet" , "Pair" , "Unit" ); // Print Quartet System.out.println( "Quartet: " + quartet); // Create Quintet from Quartet Quintet<String, String, String, String, String> quintet = quartet.addAt4( "Quintet" ); // Print Quintet System.out.println( "Quintet: " + quintet); } }

   输出：

   Quartet: [Quartet, Triplet, Pair, Unit]
   Quintet: [Quartet, Triplet, Pair, Unit, Quintet]
