Java help -> boolean prob.

Elfman

Hi all !

Been racking my head with this lilttle prob regrading declaring boolean varible ;

public static boolean NotA, NotB, NotE, NotG, NotJ, NotL, NotO, NotR, NotV;
//Flags to stop unessesary
//Checks later on.

NotA = NotB = NotE = NotG = NotJ = NotL = NotO = NotR = NotV = true;

the compile error reads :

.\LetterCheck.java:17: <identifier> expected
NotA = NotB = NotE = NotG = NotJ = NotL = NotO = NotR = NotV = true;
^

Any Help would be great thanks all

Try removing "static" from "public static boolean"

Thanks for quick reply didn't work got more errors.

Recon it needs the static any other tips ? the whole code is attched if neone wants a look but i thinks it's this line si the problem.

The problem is you are trying to put executable code into the class where no code block can run.

If you really must do something like you have above it should be like this.

public static boolean NotA, NotB, NotE, NotG, NotJ, NotL, NotO, NotR, NotV;
//Flags to stop unessesary
//Checks later on.
static {
  NotA = NotB = NotE = NotG = NotJ = NotL = NotO = NotR = NotV = true;
}

Be warned that the static block runs once only. If they are instance variables you should init them in the constructor. Also be aware that the compiler basically stitches static execution blocks together in order of how they are written.

However you should know that variables declared in the top level of the class are initialised to thier default values. In this case those booleans would automatically be false.

Post these new errors, they'll tell us more.

Just to prove it..

class Test { 

    static boolean a, b, c, d, e, f, g;

    static { 
        a = b = c = d = e = f = g = true;
    }

    public static void main(String[] args) { 
        System.out.println(g);
    }

}

incidently the line below is also wrong...

boolean True = 0;

Apart from giving a variable name of True (which is terrible thing to do), booleans can only equate to true/false. Not to a value.

You would also be better off getting rid of those comment lines at the end of if statements and just using proper indentation as it makes the code hard to read.

Oh yeah i get what your saying thanks a million i'l have to get a think over.

thanks again
