AtomicReferenceArray类的set()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。此方法使用读取的内存语义来设置值,就像将变量声明为变量的易失性类型一样。
用法:
public final void set(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set()方法:
程序1:
// Java program to demonstrate
// AtomicReferenceArray.set() 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.set(0, 2345);
ref.set(1, 543);
ref.set(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:
Value of index 0 = 2345 Value of index 1 = 543 Value of index 2 = 322
程序2:
// Java program to demonstrate
// AtomicReferenceArray.set() 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.set(0, "C");
ref.set(1, "PYTHON");
ref.set(2, "TS");
ref.set(3, "C++");
ref.set(4, "C");
// print
for (int i = 0; i < 5; i++) {
System.out.println(ref.get(i));
}
}
}
输出:
C PYTHON TS C++ C
