Java 中的 AtomicReferenceArray setPlain()方法，示例

原文:https://www . geeksforgeeks . org/atomicreferencearray-set lain-method-in-Java-with-examples/

一个原子引用数组类的set lain()方法用于将索引 I 处的元素的值设置为新值。索引 I 和 newValue 都作为参数传递给该方法。此方法使用设置的内存语义来设置值，就像变量被声明为非易失性和非最终的一样。

语法:

public final void setPlain(int i, E newValue)

参数:该方法接受:

i 是执行操作的原子引用数组的索引，
新值是要设置的新值。

返回值:此方法不返回任何内容。

以下程序说明了 setPlain()方法: 程序 1:

// Java program to demonstrate
// setPlain() method

import java.util.concurrent.atomic.*;

public class GFG {

    public static void main(String[] args)
    {

        // create an atomic reference object.
        AtomicReferenceArray<Integer> ref
            = new AtomicReferenceArray<Integer>(5);

        // set some value and print
        ref.setPlain(0, 9876);
        ref.setPlain(1, 1234);
        ref.setPlain(2, 3212);

        System.out.println("Value of index 0 = "
                           + ref.get(0));
        System.out.println("Value of index 1 = "
                           + ref.get(1));
        System.out.println("Value of index 2 = "
                           + ref.get(2));
    }
}

Output:

程序 2:

// Java program to demonstrate
// setPlain() method

import java.util.concurrent.atomic.*;

public class GFG {

    public static void main(String[] args)
    {

        // create an atomic reference object
        AtomicReferenceArray<String> ref
            = new AtomicReferenceArray<String>(5);

        // set some value
        ref.setPlain(0, "JS");
        ref.setPlain(1, "EMBER");
        ref.setPlain(2, "REACT");
        ref.setPlain(3, "C++");
        ref.setPlain(4, "C");

        // print
        for (int i = 0; i < 5; i++) {
            System.out.println(ref.get(i));
        }
    }
}
