示例 1

import java.util.concurrent.atomic.AtomicLong;

public class AtomicLongGetAndAddExample1 {
	
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong();
		//adds this number to the Initialized value
		Long result = atomiclong.getAndAdd(10);
		//Prints the added value before addition to the Initialized value
		System.out.println(result);
	}

}

输出

import java.util.concurrent.atomic.AtomicLong;

public class AtomicLongGetAndAddExample2 {
	
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(10);
		//adds this number to the Initialized value
		Long result = atomiclong.getAndAdd(10);
		//Prints the added value before addition to the Initialized value
		System.out.println(result);
	}

}

输出

import java.util.concurrent.atomic.AtomicLong;

public class AtomicLongGetAndAddExample3 {
	
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-5);
		//adds this number to the Initialized value
		Long result = atomiclong.getAndAdd(10);
		//Prints the added value before addition to the Initialized value
		System.out.println(result);
	}

}

示例 4

import java.util.concurrent.atomic.AtomicLong;

public class AtomicLongGetAndAddExample4 {
	
	public static void main (String [] args) {
		AtomicLong atomiclong = new AtomicLong(-20);
		//adds this number to the Initialized value
		Long result = atomiclong.getAndAdd(-20);
		//Prints the added value before addition to the Initialized value
		System.out.println(result);
	}

}
