Java中的LongAdder类创建一个初始和为零的新加法器。 Java.LongAdder.reset()是Java中的内置方法,可将总和重置为零。创建类的对象时,其初始值为零。
用法:
public void reset()
参数:该函数不接受任何参数。
返回值:此方法不返回任何值
下面的程序演示了上述函数:
示例1:
// Java program to demonstrate
// the LongAdder.reset() 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);
// reset operation on num
num.reset();
// Print after value
System.out.println("After reset: "
+ num);
}
}
输出:
Initial value is: 0 After addition of 6, value is: 6 After addition of 5, value is: 11 After reset: 0
示例2:
// Java program to demonstrate
// the LongAdder.reset() 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 100 to it
num.add(100);
// Print the final value
System.out.println("After addition"
+ " of 100, value is: "
+ num);
// reset operation on num
num.reset();
// Print after value
System.out.println("After reset: "
+ num);
}
}
输出:
Initial value is: 0 After addition of 10, value is: 10 After addition of 100, value is: 110 After reset: 0
