    Default How to call string in another class in java?

    Hi to all..
    i ask for a little help thanks
    here's my problem, i need to call two different strings in the other class and provide any value for it. here's what ive done so far

    Here's my first class
    public class Student
    {
    String Name,Course;
     
    public void setNme(String inputName)
    {
    Name=inputName;
    }
    public String getNme()
    {
    return Name;
    }
     
    public void setCrs(String inputCourse)
    {
    Course=inputCourse;
    }
    public String getCrs()
    {
    return Course;
    }
    }

    Here's the other one that call the Student Class

    public class Outcome
    {
    public static void main(String[]args)
    {
     
    Student a = new Student();
    a.setNme("charles");
    System.out.print(a.getNme());
     
    Student b = new Student();
    b.setCrs("\ncB.S. Computer Science");
    System.out.print(b.getCrs());
    }
    }

    I can call the first String which is Name but the second one which is Course i always get an error. any help would do but please dont use advance scripts, just the basic only thanks.

    Here's the error message i get.

    Hello tazjaime and welcome to the forums

    I just compiled the code you posted above and it all works fine?

    I get the output:

    charles
    cB.S. Computer Science

    When is this error generated?

    i dont know why i got that error but when i copy paste it in a new notepad it works but here's my other problem...

    when using "int"

    Java Code
    public class Outcome
    {
    public static void main(String[]args)
    {
    Student a = new Student();
    a.setNme("\nCharles Jaime");
    System.out.print(a.getNme());
     
    Student b = new Student();
    b.setStudNum("\n0510180");
    System.out.print(b.getStudNum());
     
    Student c = new Student();
    c.setCrs("\nB.S. Computer Science");
    System.out.print(c.getCrs());
    }
    }
    Java Code
    public class Student
    {
    String Name,Course;
    int StudentNumber;
     
        public void setNme(String inputName)
        {
        Name=inputName;
        }
        public String getNme()
        {
        return Name;
        }
     
        public void setStudNum(int inputStudentNumber)
        {
        StudentNumber=inputStudentNumber;
        }
        public int getStudNum()
        {
        return StudentNumber;
        }
     
        public void setCrs(String inputCourse)
        {
        Course=inputCourse;
        }
        public String getCrs()
        {
        return Course;
        }
     
    }
    Here's the error when using int or double

    The value 0510180 is too long to be an Integer.

    I suggest handling it as a String like this:

    public class Student {
        String Name, Course;
        String StudentNumber;
     
        public void setNme(String inputName) {
            Name = inputName;
        }
     
        public String getNme() {
            return Name;
        }
     
        public void setStudNum(String inputStudentNumber) {
            StudentNumber = inputStudentNumber;
        }
     
        public String getStudNum() {
            return StudentNumber;
        }
     
        public void setCrs(String inputCourse) {
            Course = inputCourse;
        }
     
        public String getCrs() {
            return Course;
        }
     
    }
    public class Outcome {
     
        public static void main(String[] args) {
            Student a = new Student();
            a.setNme("Charles Jaime");
            System.out.println(a.getNme());
     
            Student b = new Student();
            b.setStudNum("0510180");
            System.out.println(b.getStudNum());
     
            Student c = new Student();
            c.setCrs("B.S. Computer Science");
            System.out.println(c.getCrs());
        }
    }

    Also, I personally would use:

    System.out.print[B]ln[/B](b.getStudNum());

    Instead of including the new line char in the String.

    b.setStudNum("[B]\n[/B]0510180");
