public class Demo01 {
    public static void main(String[] args) {
        String 王者荣耀 = "倔强青铜";
        System.out.println(王者荣耀);

        //大小写十分敏感
        String Man = "AI福";
        String man = "AI福";

        String name = "AI福";

        //取名规范
        String Ahello = "AI福";
        String hello = "AI福";
        String $hello = "AI福";
        String _hello = "AI福";

        String _1 = "AI福";
        //String class = "AI福";

        /*
        String 1hello = "AI福";
        String Ahello = "AI福";
        String Ahello = "AI福";
