原文:https://www . geesforgeks . org/long 累加器-get-method-in-Java-with-examples/

java。long 累加器. get() 是 java 中的一个内置方法，返回 long 累加器对象的当前值。

语法:

public long get()

参数:该方法不接受任何参数。

返回值:该方法返回 long 累加器对象的当前值。

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

程序二 :

// 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
