Java AtomicReferenceArray getAcquire()用法及代碼示例

AtomicReferenceArray類的getAcquire()方法用於返回具有與memory_order_acquire排序兼容的內存排序效果的此AtomicReferenceArray對象的索引i處的元素的值。

用法:

public final E getAcquire(int i)

參數：此方法接受索引i以獲取值。

返回值：此方法返回索引i處的當前值。

以下示例程序旨在說明getAcquire()方法：
程序1:

// Java program to demonstrate 
// AtomicReferenceArray.getAcquire() method 
  
import java.util.concurrent.atomic.AtomicReferenceArray; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create an atomic reference array 
        // object which stores Integer. 
        AtomicReferenceArray<Integer> array 
            = new AtomicReferenceArray<Integer>(5); 
  
        // set some value in array 
        array.set(0, 1213); 
        array.set(1, 1344); 
        array.set(2, 1453); 
        array.set(3, 1452); 
  
        // get and print the value 
        // using getAcquire method 
        for (int i = 0; i < 4; i++) { 
  
            int value = array.getAcquire(i); 
            System.out.println("value at "
                               + i + " = " + value); 
        } 
    } 
}

輸出：

程序2:

// Java program to demonstrate 
// AtomicReferenceArray.getAcquire() method 
  
import java.util.concurrent.atomic.AtomicReferenceArray; 
  
public class GFG { 
    public static void main(String[] args) 
    { 
  
        // create an atomic reference array object 
        // which stores String. 
        AtomicReferenceArray<String> array 
            = new AtomicReferenceArray<String>(5); 
  
        // set some value in array 
        array.set(0, "GEEKS"); 
        array.set(1, "FOR"); 
        array.set(2, "GEEKS"); 
  
        // get and print the value using get method 
        for (int i = 0; i < 2; i++) { 
  
            String value = array.getAcquire(i); 
            System.out.println("value at "
                               + i + " = " + value); 
        } 
    } 
}

輸出：
