Java中的 LongAdder add() 方法及示例
Java中的LongAdder 类创建一个初始和为零的新加法器。 Java.LongAdder.add()是Java中的一个内置方法,用于添加给定的值。
句法:
public void add(long x)
参数:该函数接受单个参数x ,该参数指定要添加的值。
返回值:该方法不返回任何值。
下面的程序演示了上述函数:
方案一:
// Java program to demonstrate
// the LongAdder.add() method
import java.lang.*;
import java.util.concurrent.atomic.LongAdder;
public class GFG {
public static void main(String args[])
{
// Initialized with 0
LongAdder num = new LongAdder();
// Print the initial value
System.out.println("Initial value is: "
+ num);
// Add 6 to it
num.add(6);
// Print the final value
System.out.println("After addition"
+ " of 6, value is: "
+ num);
// Add 5 to it
num.add(5);
// Print the final value
System.out.println("After addition"
+ " of 5, value is: "
+ num);
}
}
输出:
Initial value is: 0
After addition of 6, value is: 6
After addition of 5, value is: 11
方案二:
// Java program to demonstrate
// the LongAdder.add() method
import java.lang.*;
import java.util.concurrent.atomic.LongAdder;
public class GFG {
public static void main(String args[])
{
// Initialized with 0
LongAdder num = new LongAdder();
// Print the initial value
System.out.println("Initial value is: "
+ num);
// Add 10 to it
num.add(10);
// Print the final value
System.out.println("After addition"
+ " of 10, value is: "
+ num);
// Add -5 to it
num.add(-5);
// Print the final value
System.out.println("After addition"
+ " of -5, value is: "
+ num);
}
}
输出:
Initial value is: 0
After addition of 10, value is: 10
After addition of -5, value is: 5
