Java中的 LongAdder intValue() 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.intValue()是Java中的一个内置方法，它将总和作为 int 值返回。创建类的对象时，其初始值为零。

句法：

public int intValue()

参数：该函数不接受任何参数。

返回值：该方法返回一个int 值，表示此 LongAdder 的总和

下面的程序演示了上述函数：

方案一：

// Java program to demonstrate
// the LongAdder.intValue() 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);
  
        // intValue operation on num
        num.intValue();
  
        // Print after value
        System.out.println("Sum of LongAdder as int: "
                           + num);
    }
}

输出：

Initial value is: 0
After addition of 6, value is: 6
After addition of 5, value is: 11
Sum of LongAdder as int: 11

方案二：

// Java program to demonstrate
// the LongAdder.intValue() 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);
  
        // intValue operation on num
        num.intValue();
  
        // Print after value
        System.out.println("Sum of LongAdder as int: "
                           + num);
    }
}

输出：

Initial value is: 0
After addition of 10, value is: 10
After addition of 100, value is: 110
Sum of LongAdder as int: 110
