JavaTuples - Decade Class
Introduction
org.javatuples.Decade 类表示一个有十个元素的元组。
The org.javatuples.Decade class represents a Tuple with ten elements.
Class Declaration
以下是对 org.javatuples.Decade 类的声明 −
Following is the declaration for org.javatuples.Decade class −
public final class Decade<A, B, C, D, E, F, G, H, I, J>
extends Tuple
implements IValue0<A>, IValue1<B>,
IValue2<C>, IValue3<D>, IValue4<E>,
IValue5<F>, IValue6<G>, IValue7<H>,
IValue8<I>, IValue9<J>Class Constructor
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. |
Class Methods
Sr.No. |
Method & Description |
1 |
static <X> Decade<X,X,X,X,X,X,X,X,X,X > fromArray(X[] array) Create tuple from array. |
2 |
static <X> Decade<X,X,X,X,X,X,X,X,X,X> fromCollection(Collection<X> collection) Create tuple from collection. |
3 |
static <X> Decade<X,X,X,X,X,X,X,X,X,X> fromIterable(Iterable<X> iterable) Create tuple from iterable. |
4 |
static <X> Decade<X,X,X,X,X,X,X,X,X> fromIterable(Iterable<X> 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<B,C,D,E,F,G,H,I,J> 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 |
<X> Decade<X,B,C,D,E,F,G,H,I,J> setAt0(X value) Set the value of the tuple at index 0. |
9 |
static <A> Decade<A,B,C,D,E,F,G,H,I,J> 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. |
Methods inherite
此类从以下类中继承方法：
This class inherits methods from the following classes −
-

-
Object
Example
让我们看看 Ennead 类的作用。我们将在其中看到如何使用各种方法。
Let’s see Ennead Class in action. Here we’ll see how to use various methods.
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 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<Integer, Integer, Integer, Integer,
Integer,Integer,Integer,Integer, Integer, Integer>
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<Integer> 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<Integer, Integer, Integer, Integer,Integer,
Integer,Integer, Integer, Integer> ennead = decade.removeFrom0();
System.out.println(ennead);
Decade<Integer, Integer, Integer, Integer, Integer,
Integer, Integer, Integer,Integer, Integer>
decade1 = Decade.fromCollection(list);
System.out.println(decade1);
}
}Verify the result
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
