原文:https://www . geeksforgeeks . org/atomicintger-get-method-in-Java-with-examples/

java . util . concurrent . atomic . atomicinteger . get()是 Java 中的一个内置方法,它返回日期类型 int 的当前值。

语法:

public final int get()

参数:函数不接受任何参数。

返回值:函数返回当前值

下面的程序演示了该功能:

程序 1:

// Java Program to demonstrates
// the get() function

import java.util.concurrent.atomic.AtomicInteger;

public class GFG {
    public static void main(String args[])
    {

        // Initially value as 0
        AtomicInteger val
            = new AtomicInteger(0);

        val.addAndGet(7);

        // Prints the updated value
        System.out.println("Previous value: "
                           + val);

        // Gets the current value
        int res = val.get();

        System.out.println("current value: "
                           + res);
    }
}

输出:

Previous value: 7
current value: 7

程序二:

// Java Program to demonstrates
// the get() function

import java.util.concurrent.atomic.AtomicInteger;

public class GFG {
    public static void main(String args[])
    {

        // Initially value as 18
        AtomicInteger val = new AtomicInteger(18);

        val.addAndGet(7);

        // Prints the updated value
        System.out.println("Previous value: " + val);

        // Gets the current value
        int res = val.get();

        System.out.println("current value: " + res);
    }
}

输出:

Previous value: 25
current value: 25
