Java_自增和自减运算符的简单使用

class Operation
{
	public static void main(String args[])
	{
		int x = 5;
		int y = 2;
		int a = y + (x++);//和c语言一样，先使用x的值，再使x的值加1。
		System.out.println("a = " + a);
		System.out.println("x = " + x);
		int b = y + (++x);//先使x的值加1，再使用x的值。
		System.out.println("b = " + b);
		System.out.println("x = " + x);
		int c = x + (y--);
		System.out.println("c = " + c);
		System.out.println("y = " + y);
		int d = x + (--y);
		System.out.println("d = " + d);
		System.out.println("y = " + y);
	}
}
