Testing and commissioning

My debugging and testing process:

A The source code is as follows

Public class Admin extends User {

Public Admin (string name, string call, int age, String sex,

String loginname, string password, string school) {

Super (Name, call, age, sex, loginname, password, school);

}

}

Public class Student extends User {

Public Student (string name, String call, int. age, String sex,

String loginname, string password, string school) {

Super (Name, call, age, sex, loginname, password, school);

}

}

Public class Teacher extends User {

Public Teacher (string name, String call, int. age, String sex,

String loginname, string password, string school) {

Two: The error code in the program has been successfully corrected by our team, I will highlight the test results:

The code debugging and testing process has been successfully demonstrated, you can run the code through the line debugging, what comments can be feedback to me.
