\n command

[~Rob]

Hi all, first post here!!


Anyways, I'm using BlueJ at uni *sighs* and I've been asked to turn n output into a toString method. Now, I have everything set up but I want it on multiple lines using the \n command, but BlueJ doesn't seem to support that by default. Where is the option to enable it?

TIA,
Rob

Mean, something like?

public class Person {
    private String firstName;
    private String mi;
    private String lastName;
        
    public Person() {
    }    
    
    public Person(String lastName, String firstName, String mi) {
        this.lastName = lastName;
        this.firstName = firstName;
        this.mi = mi;
    }
   
    public String toString() {
        return lastName + ",\n" + firstName + " " + mi + ".\n";
    }
    
}

Exactly the same as what I was getting. The spec says to use toString to make the output user friendly.

I had it looking great with println!

\n is not a command, its an escape character. Its not an option that can be turned on or off. I have never used BueJ, but I would suspect that since the entryfield that is displaying the data is single line, the tool itself is replacing the '\n' character with the actual string "\n" to show where a new line is.

Maybe?

Do you mean a newline object?

class Newline
{
    String toString()
    {
        return "\n";
    }
}

Its very simple to use. Pure genius if you ask me

System.out.print("Line 1" + (new Newline()) + "Line 2");

^^ Thanks for that... NOT


anywhos, if it looks like BlueJ is being a stubborn pile of crap (wouldn't supprise me) then that's probably what it is.

I'll carry on with a bit of println.

Thanks
