如何使用java代码对两个int类型的整数进行互换呢?

实现思路:
    方式1.定义临时变量对数据进行缓存,实现互换操作
	方式2:使用加减法的方式,对变量进行互换

public class SwapData { 
	public static void main(String[] args) {
		swap1(888,222);
		swap2(888,222);
	}
	
	public static void swap1(int a, int b) {
		System.out.println("before swap: a=" + a + ",b=" + b);
		int temp = 0;
		temp = a;
		a = b;
		b = temp;
		System.out.println("after  swap: a=" + a + ",b=" + b);
	}
 
	public static void swap2(int a, int b) {
		System.out.println("before swap: a=" + a + ",b=" + b);
		a = a + b;
		b = a - b;
		a = a - b;
		System.out.println("after  swap: a=" + a + ",b=" + b);
	}
}
