Java AtomicReferenceArray setPlain()用法及代码示例


AtomicReferenceArray类的setPlain()方法用于将索引i处的元素值设置为newValue。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,就好像该变量被声明为非易失性且非最终值一样。

用法:

public final void setPlain(int i, E newValue)

参数:此方法接受:


  • i这是执行操作的AtomicReferenceArray的索引,
  • newValue 这是要设置的新值。

返回值:此方法不返回任何内容。

以下示例程序旨在说明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)); 
    } 
}
输出:

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)); 
        } 
    } 
}
输出:
