Java中的 LongAccumulator get() 方法及示例

Java.LongAccumulator.get()是Java中的一个内置方法,它返回 LongAccumulator 对象的当前值。

句法:

public long get()

参数:此方法不接受任何参数。

返回值:该方法返回 LongAccumulator 对象的当前值。

下面的程序说明了上述方法:

程序 1

// Program to demonstrate the get() method
  
import java.lang.*;
import java.util.concurrent.atomic.LongAccumulator;
  
public class GFG {
    public static void main(String args[])
    {
        LongAccumulator num = new LongAccumulator(Long::sum, 0L);
  
        // accumulate operation on num
        num.accumulate(2);
        num.accumulate(10);
  
        // Gets current value
        long x = num.get();
  
        // Print after get operation
        System.out.println(" the current value is: " + x);
    }
}
输出:
the current value is: 12

方案二

// Program to demonstrate the get() method
  
import java.lang.*;
import java.util.concurrent.atomic.LongAccumulator;
  
public class GFG {
    public static void main(String args[])
    {
        LongAccumulator num = new LongAccumulator(Long::sum, 0L);
  
        // accumulate operation on num
        num.accumulate(22);
        num.accumulate(10);
  
        // Gets current value
        long x = num.get();
  
        // Print after get operation
        System.out.println(" the current value is: " + x);
    }
}
输出:
the current value is: 32
