Java code about Enrollment System

Please help.

So this is the code:

import java.util.Scanner;

class User {

String username;

String password;

String role;

public User(String username, String password, String role) {

this.username = username;

this.password = password;

this.role = role;

}

public String getUsername() {

return username;

}

public String getPassword() {

return password;

}

public String getRole() {

return role;

}

}

class Course {

String courseCode;

String courseTitle;

int units;

public Course(String courseCode, String courseTitle, int units) {

this.courseCode = courseCode;

this.courseTitle = courseTitle;

this.units = units;

}

public String getCourseCode() {

return courseCode;

}

public String getCourseTitle() {

return courseTitle;

}

public int getUnits() {

return units;

}

}

class EnrollmentSystem {

User[] users = new User[10];

int userCount = 0;

}

Problem 1: When I add a 2nd course as an admin, the "Enter course code:" and the "Enter course title:" began to join as one line and that goes on and on. Please, kindly edit and fix it.

Problem 2: When I'm about to enroll in a course as a student, the "Enter course code:" and the "You have enrolled in:" joined as one line and I'm not yet inputting something that I enrolled in a certain course which "csit2 programming2" appeared. Please, kindly edit and fix it.

Thank you so much in advance.
