AtomicReferenceArray类的lazySet()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 效应的值来设置值,以确保在此访问之后不会重新排序先前的加载和存储。
用法:
public final void lazySet(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lazySet()方法:
程序1:
// Java program to demonstrate
// AtomicReferenceArray.lazySet() 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>(3);
// set some value using lazySet() and print
ref.lazySet(0, 1234);
ref.lazySet(1, 4322);
ref.lazySet(2, 2345);
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
// AtomicReferenceArray.lazySet() method
import java.util.concurrent.atomic.*;
public class GFG {
public static void main(String[] args)
{
// create an atomic reference object
AtomicReferenceArray<String>
HIMALAYAN_COUNTRY
= new AtomicReferenceArray<String>(5);
// set some value
HIMALAYAN_COUNTRY.lazySet(0, "INDIA");
HIMALAYAN_COUNTRY.lazySet(1, "CHINA");
HIMALAYAN_COUNTRY.lazySet(2, "PAKISTAN");
HIMALAYAN_COUNTRY.lazySet(3, "BHUTAN");
HIMALAYAN_COUNTRY.lazySet(4, "NEPAL");
// print
for (int i = 0; i < 5; i++) {
System.out.println(
HIMALAYAN_COUNTRY.get(i));
}
}
}
