Implementing Decade Using Ennead Class

Problem Description

如何使用 Ennead 类实现 Decade 类？

How to implement Decade class using Ennead class?

Example

以下示例描述了如何完成以上任务。每个元组都有 add() 和 addAtX() 方法来转换元组。

Following example shows how to accomplish the above task. Each tuple has add() and addAtX() methods to convert the tuple.

在 C:>JavaTuples 中创建一个名为 TupleTester 的 Java 类文件。

Create a java class file named TupleTester in C:\>JavaTuples.

文件：TupleTester.java

File: TupleTester.java

package com.tutorialspoint;
import org.javatuples.Decade;
import org.javatuples.Ennead;
public class TupleTester {
   public static void main(String args[]){
      Ennead<Integer, Integer, Integer, Integer, Integer, Integer,
         Integer, Integer, Integer> ennead = Ennead.with(5,6,7,8,9,10,11,12,13);
      System.out.println(ennead);
      Decade<Integer, Integer, Integer, Integer, Integer, Integer,
         Integer, Integer, Integer, String> decade = ennead.add("test");

      Decade<String, Integer, Integer, Integer, Integer, Integer,
         Integer, Integer, Integer, Integer> decade1 = ennead.addAt0("test");

      System.out.println(decade);
      System.out.println(decade1);
   }
}

Verify the result

使用以下 javac 编译器编译类：

Compile the classes using javac compiler as follows −

C:\JavaTuples>javac -cp javatuples-1.2.jar ./com/tutorialspoint/TupleTester.java

现在运行 TupleTester 查看结果：

Now run the TupleTester to see the result −

C:\JavaTuples>java  -cp .;javatuples-1.2.jar com.tutorialspoint.TupleTester

Output

验证输出

Verify the Output

[5, 6, 7, 8, 9, 10, 11, 12, 13]
[5, 6, 7, 8, 9, 10, 11, 12, 13, test]
[test, 5, 6, 7, 8, 9, 10, 11, 12, 13]
