java 类型转换

隐式转换

1. (byte，short，char)->int->long->float->double

public class test {
    public static void main(String[] args) {
        byte a = 10;
        int b=a;
        long c=a;
        float d=a;
        double e=a;
        System.out.println(a);
        System.out.println(b);
        System.out.println(c);
        System.out.println(d);
        System.out.println(e);
        
        char f='c';
        int g=f; //char类型会转换为ascii码值
        System.out.println(g);
    }
}

2. byte，short，char是评级的,不能自动转换

强制类型转换
