介绍

org.javatuples.Ennead类表示具有九个元素的元组。

类声明

以下是org.javatuples.Ennead类的声明-

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

类构造器

Sr.No. Constructor & Description
1

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

This creates a Ennead Tuple.

类方法

Similarly setAt1() upto setAt8() set the value at index 1, and so on.

Sr.No. Method & Description
1

Decade add(Unit tuple)

This method returns a Decade tuple.
2

Decade add(X0 value)

This method add a value to the tuple and returns a Decade tuple.

3

Decade addAt0(Unit value)

This method add a Unit tuple at index 0 and returns a Decade tuple.

Other similar method are addAt1(Unit value) which add a unit at index0 and have similar methods upto addAt8(Unit).
4

Decade addAt0(X0 value)

This method add a value at index 0 and returns a Decade tuple.

Other similar method are addAt1(X0 value) which add a value at index0 and have similar methods upto addAt8() with one parameter.
5

static Ennead fromArray(X[] array)

Create tuple from array.
6

static Ennead fromCollection(Collection collection)

Create tuple from collection.
7

static Ennead fromIterable(Iterable iterable)

Create tuple from iterable.
8

static Ennead fromIterable(Iterable iterable, int index)

Create tuple from iterable, starting from the specified index.
9

int getSize()

Return the size of the tuple.
10

A getValue0()

Returns the value of the tuple at index 0.

Similarly getValue1() upto getValue8() returns the value at index 1 and so on.
11

Octet removeFrom0()

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

Similarly removeFrom1() upto removeFrom8() returns the tuple after removing value of the tuple at index 1 and so on.
12

Ennead setAt0(X value)

Set the value of the tuple at index 0.
13

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

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;
import org.javatuples.Octet;
public class TupleTester {
   public static void main(String args[]){
      Ennead 
      ennead = Ennead.with(5, 6, 7,8,9,10,11,12,13);
      System.out.println(ennead);
      boolean isPresent = ennead.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);
      Decade decade = ennead.add("Test");
      System.out.println(decade);
      Integer value = ennead.getValue0();
      System.out.println(value);
      Octet octet = ennead.removeFrom0();
      System.out.println(octet);
      Ennead ennead1 = Ennead.fromCollection(list);   
      System.out.println(ennead1);
   }
}

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