Java AtomicReferenceArray setRelease()用法及代码示例

AtomicReferenceArray类的setRelease()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VarHandle.setRelease(java.lang.Object…)指定的具有 memory 效果的值进行设置。此方法具有与memory_order_release排序兼容的内存排序效果。

用法:

public final void setRelease(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setRelease()方法：
程序1:

// Java program to demonstrate 
// setRelease() 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.setRelease(0, 1324); 
        ref.setRelease(1, 144); 
        ref.setRelease(2, 322); 
  
        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 
// setRelease() method 
  
import java.util.concurrent.atomic.*; 
  
public class GFG { 
  
    public static void main(String[] args) 
    { 
  
        // create an atomic reference object.c 
        AtomicReferenceArray<String> ref 
            = new AtomicReferenceArray<String>(5); 
  
        // set some value 
        ref.setRelease(0, "C"); 
        ref.setRelease(1, "PYTHON"); 
        ref.setRelease(2, "TS"); 
        ref.setRelease(3, "C++"); 
        ref.setRelease(4, "C"); 
  
        // print 
        for (int i = 0; i < 5; i++) { 
            System.out.println(ref.get(i)); 
        } 
    } 
}
