Java LongAdder floatValue()用法及代码示例

Java中的LongAdder类创建一个初始和为零的新加法器。 Java.LongAdder.floatValue()是java中的一个内置方法，该方法将总和作为浮点值返回。创建类的对象时，其初始值为零。

用法:

public float floatValue()

参数：该函数不接受任何参数。

返回值：该方法返回一个浮点值，该值表示此LongAdder的总和

下面的程序演示了上述函数：

示例1:

// Java program to demonstrate 
// the LongAdder.floatValue() 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); 
  
        // floatValue operation on num 
        num.floatValue(); 
  
        // Print after value 
        System.out.println("Sum of LongAdder as float: "
                           + 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 float: 11

示例2:

// Java program to demonstrate 
// the LongAdder.floatValue() 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); 
  
        // floatValue operation on num 
        num.floatValue(); 
  
        // Print after value 
        System.out.println("Sum of LongAdder as float: "
                           + 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 float: 110
