stupid java

theliam

im not used to java but trying to test something, gwtting errors for this line, it will eventually not be needed as the program will read it in from a file but just declaring it as is for now

layout[][]={{" "," "," ","#","#","#"},{" "," ","#","#"," ","#"," ","#","#","#","#"},{" ","#","#"," "," ","#","#","#"," "," ","#"},{"#","#"," ","$"," "," "," "," "," "," ","#"},{"#"," "," "," ","@","$"," ","#"," "," ","#"},{"#","#","#"," ","$","#","#","#"," "," ","#"},{" "," ","#"," "," ","#",".","."," "," ","#"},{" ","#","#"," ","#","#",".","#"," ","#","#"},{" ","#"," "," "," "," "," "," ","#","#"},{" ","#"," "," "," "," "," ","#","#"},{" ","#","#","#","#","#","#","#"}};

is there anything wrong with it?

How is your variable type declaired? has it been declaired?

I.e

String[][] layout = new String[][];
layout ={{" "," "," ","#","#","#"}, ...

Yeah, it's unreadable. We have whitespace for a reason y'know

layout[][]={
    {" ", " ", " ", "#", "#", "#"}, 
    {" ", " ", "#", "#", " ", "#", " ", "#", "#", "#", "#"}, 
    {" ", "#", "#", " ", " ", "#", "#", "#", " ", " ", "#"}, 
    {"#", "#", " ", "$", " ", " ", " ", " ", " ", " ", "#"}, 
    {"#", " ", " ", " ", "@", "$", " ", "#", " ", " ", "#"}, 
    {"#", "#", "#", " ", "$", "#", "#", "#", " ", " ", "#"}, 
    {" ", " ", "#", " ", " ", "#", ".", ".", " ", " ", "#"}, 
    {" ", "#", "#", " ", "#", "#", ".", "#", " ", "#", "#"}, 
    {" ", "#", " ", " ", " ", " ", " ", " ", "#", "#"}, 
    {" ", "#", " ", " ", " ", " ", " ", "#", "#"}, 
    {" ", "#", "#", "#", "#", "#", "#", "#"}
};

Also, what are the errors you're getting?

theliam

its declared

char[][] layout;
    layout= new char[20][20];

errors are cannot find symbol class layout, class main
not a statement
; expected
not a statement
; expected
...

You have already defined the array above and initialized it therefore you cannot initialize it again.

Alternatively you can define it as

char[][] layout ={ <followed by the set of chars in the array>};
Also you have defined them as char not string yet you are placing strings in them not chars.

doh.

single thingys, right? '#'

also, when using toCharArray() for strings, will it take endline characters in as well?

thats sorted but now whem im printing them out using

System.out.println(layout[i][j]);

it prints each character on a new line...
how do i make it not do that?
i have no /n etc.

I dont do Java but I'd imagine that you'll have to use a method instead of PrintLn as that's what it's meant to do (print to a new line).

System.out.Print
