基本赋值运算符

就是“=”

//先看"="右边，把数据10赋值给左边的变量a存储
int a = 10;

扩展赋值运算符

注意：

扩展的赋值运算符隐含了强制类型转换

class A13{
    public static void main(String[] args) {
        //赋值运算符
        int a = 10;
        int b = 2;
        //a = (int)a + b
        a+=b;
        System.out.println(a);

        int c = 10;
        int d = 2;
        //c = (int)c - d
        c -= d;
        System.out.println(c);
        
        int e = 10;
        int f = 2;
        //e = (int)e /f
        e /= f;
        System.out.println(e);
        
        byte g = 10;
        byte h = 2;
        //g = (byte)g * h
        System.out.println(g);
    }
}
