Java.util.concurrent.atomic.AtomicLong.set()是Java中的內置方法,可更新先前的值並將其設置為在參數中傳遞的新值。
用法:
public final void set(long newVal)
參數:該函數接受將要更新的單個必需參數newVal。
返回值:該函數不返回任何內容。
以下示例程序旨在說明上述方法:
示例1:
// Java program that demonstrates
// the set() function
import java.util.concurrent.atomic.AtomicLong;
public class GFG {
public static void main(String args[])
{
// Initially value as 0
AtomicLong val = new AtomicLong(0);
System.out.println("Previous value: "
+ val);
val.set(10);
// Prints the updated value
System.out.println("Current value: "
+ val);
}
}
輸出:
Previous value: 0 Current value: 10
示例2:
// Java program that demonstrates
// the set() function
import java.util.concurrent.atomic.AtomicLong;
public class GFG {
public static void main(String args[])
{
// Initially value as 18
AtomicLong val = new AtomicLong(18);
System.out.println("Previous value: "
+ val);
val.set(200);
// Prints the updated value
System.out.println("Current value: "
+ val);
}
}
輸出:
Previous value: 18 Current value: 200
