介绍

org.javatuples.Decade类表示具有十个元素的元组。

类声明

以下是org.javatuples.Decade类的声明-

public final class Decade
   extends Tuple
      implements IValue0, IValue1, 
         IValue2, IValue3, IValue4,
            IValue5, IValue6, IValue7,
               IValue8, IValue9

类构造器

Sr.No. Constructor & Description
1

Decade(A value0, B value1, C value2, D value3, E value4, F value5, G value6, H value7, I value8, I value9 )

This creates a Decade Tuple.

类方法

Similarly setAt1() upto setAt9() set the value at index 1, and so on.

Sr.No. Method & Description
1

static Decade fromArray(X[] array)

Create tuple from array.
2

static Decade fromCollection(Collection collection)

Create tuple from collection.
3

static Decade fromIterable(Iterable iterable)

Create tuple from iterable.
4

static Decade fromIterable(Iterable iterable, int index)

Create tuple from iterable, starting from the specified index.
5

int getSize()

Return the size of the tuple.
6

A getValue0()

Returns the value of the tuple at index 0.

Similarly getValue1() upto getValue9() returns the value at index 1 and so on.
7

Ennead removeFrom0()

Return the tuple after removing value of the tuple at index 0.

Similarly removeFrom1() upto removeFrom9() returns the tuple after removing value of the tuple at index 1 and so on.
8

Decade setAt0(X value)

Set the value of the tuple at index 0.
9

static Decade with(A value0, B value1, C value2, D value3, E value4, F value5, G value6, H value7, I value8, I value9)

Create the tuple using given value.

方法继承

此类从以下类继承方法-

  • org.javatuples.Tuple

  • 目的

例

让我们看看Ennead类的实际应用。在这里，我们将看到如何使用各种方法。

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

文件：TupleTester.java

package com.tutorialspoint;
import java.util.ArrayList;
import java.util.List;
import org.javatuples.Decade;
import org.javatuples.Ennead;
public class TupleTester {
   public static void main(String args[]){
      Decade 
      decade = Decade.with(5, 6, 7,8,9,10,11,12,13,14);
      System.out.println(decade);
      boolean isPresent = decade.contains(5);
      System.out.println("5 is present: " + isPresent);
      List list = new ArrayList<>();
      list.add(1);
      list.add(2);
      list.add(3);
      list.add(4);
      list.add(5);
      list.add(6);
      list.add(7);
      list.add(8);
      list.add(9);
      list.add(10);
      Integer value = decade.getValue0();
      System.out.println(value);
      Ennead ennead = decade.removeFrom0();
      System.out.println(ennead);
      Decade 
         decade1 = Decade.fromCollection(list);   
      System.out.println(decade1);
   }
}

验证结果

使用javac编译器编译类，如下所示：

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

现在运行TupleTester以查看结果-

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

输出

验证输出

[5, 6, 7, 8, 9, 10, 11, 12, 13, 14]
5 is present: true
5
[6, 7, 8, 9, 10, 11, 12, 13, 14]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
