语法

返回值

此对象在转换为 long 类型后的数值表示

示例 1

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongLongValueExample1 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong();
		//Returns the initialized value as long
		Long result = atomiclong.longValue();
		//Prints the long value off atomic long
		System.out.println(result);
	}
}

输出

示例 2

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongLongValueExample2 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(2000L);
		//Returns the initialized value as long
		Long result = atomiclong.longValue();
		//Prints the long value off atomic long
		System.out.println(result);
	}
}

输出

示例 3

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongLongValueExample3 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-123456L);
		//Returns the initialized value as long
		Long result = atomiclong.longValue();
		//Prints the long value off atomic long
		System.out.println(result);
	}
}

输出

-123456

示例 4

import java.util.concurrent.atomic.AtomicLong;
public class AtomicLongLongValueExample4 {
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-20);
		atomiclong.getAndIncrement();
		//Returns the initialized value as long
		Long result = atomiclong.longValue();
		//Prints the long value off atomic long
		System.out.println(result);
	}
}

输出
