计算：

public class test {
    public static void main(String[] args) {
        int a = 10 >> 1;
        int b = a++;
        int c = ++a;
        int d = b * a++;
        System.out.println("a = " + a);
        System.out.println("b = " + b);
        System.out.println("c = " + c);
        System.out.println("d = " + d);
    }
}

结果

a = 8
b = 5
c = 7
d = 35
