Java 中 LongAdder 减量()方法，示例
原文:https://www . geesforgeks . org/long adder-减量-Java-in-method-with-examples/
Java 中的 LongAdder 类创建一个初始和为零的新加法器。爪哇。long adder . decade()是 java 中的一个内置方法，可以将该值减少 1。
语法:
public void decrement()
参数:函数不接受任何参数。
返回值:该方法不返回值。
以下程序演示了上述功能:
程序 1:
// Java program to demonstrate
// the LongAdder.decrement() 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 new value
System.out.println("After addition"
+ " of 6, value is: "
+ num);
// decrement operation on num
num.decrement();
// Print after decrement
System.out.println("After decrement, "
+ " value is: "
+ num);
}
}
Output:
Initial value is: 0
After addition of 6, value is: 6
After decrement, value is: 5
程序 2:
// Java program to demonstrate
// the LongAdder.decrement() 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 new value
System.out.println("After addition"
+ " of 10, value is: "
+ num);
// decrement operation on num
num.decrement();
// Print after decrement
System.out.println("After decrement, "
+ " value is: "
+ num);
}
}
Output:
Initial value is: 0
After addition of 10, value is: 10
After decrement, value is: 9
