每个元组都实现Iterable接口,并且可以类似于collection的方式进行迭代。
Pair pair = Pair.with("Test", Integer.valueOf(5));
for(Object object: Pair){
System.out.println(object);
}
让我们看看JavaTuples的作用。在这里,我们将看到如何迭代元组。
在C:\> JavaTuples中创建一个名为TupleTester的Java类文件。
文件:TupleTester.java
package com.tutorialspoint;
import org.javatuples.Quartet;
import org.javatuples.Triplet;
public class TupleTester {
public static void main(String args[]){
Triplet triplet = Triplet.with(
"Test1", Integer.valueOf(5), "Test2"
);
for(Object object: triplet) {
System.out.print(object + " " );
}
System.out.println();
System.out.println(triplet);
String[] strArray = new String[] {"a", "b" , "c" , "d"};
Quartet quartet = Quartet.fromArray(strArray);
for(Object object: quartet) {
System.out.print(object + " " );
}
System.out.println();
System.out.println("Quartet:" + quartet);
}
}
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
验证输出
Test1 5 Test2
[Test1, 5, Test2]
a b c d
Quartet:[a, b, c, d]
