illegal start of expression?

[The One]

iv got some code. but in the class there is an error. it says 'illegal start of expression'
it the points at a line public void operation() {
why whats wrong with it?

why does it say illegal start of expression???
below is where the line came from
public static void Calculator() {

TextField txtTotal = new TextField("");
Button button[] = new Button[10];
Button divide = new Button("/");
Button mult = new Button("*");
Button plus = new Button ("+");
Button minus = new Button("-");
Button isequalto = new Button("=");
Button clear = new Button("CA");
double num ,numtemp ;
int counter;
String strnum = "",strnumtemp = "" ;
String op = "";

public void operation() {
counter ++;
if (counter == 1) {
numtemp = num;
strnum = "";
num = 0;
}else{
if (op == "+") numtemp += num;
else if (op == "-") numtemp -= num;
else if (op == "*") numtemp = numtemp * num;
else if (op == "/") numtemp = numtemp / num;
strnumtemp = Double.toString(numtemp);
txtTotal.setText(strnumtemp);
strnum = "";
num = 0;
}
}

I'm not sure you can do this:

String strnum = "",strnumtemp = "" ;

try

String strnum = "";
String strnumtemp = "" ;

doesnt make a difference. still says illegal start of expression. in other ideas. can someone try run it and see how the problem can be fixed?

[Khalid Ali]

u should look at ur code and see where u are missing or have an extra character like double qoutes etc.
And by the way usually a compiler will give you the actual line of code and (may be exact spot) where the error is

iv looked nothin. wud u try compiling it and try to fix it cos iv done everything i can think of?

[ccoder]

You didn't terminate Calculator() with a "}". It looks like you placed the "}" after the end of operation().

hi The One

Try cutting and pasting the method in to a different area in your code ie in between two other methods. It sounds lik a glitch in the software your using.

happened to me once,....... thank me later....:)

[stevenlon]

i got it!!! try putting an extra closing brace } before 'public void operation()

[agent_x91]

I'm not sure you can do this:

String strnum="",strnumtemp="";

Just in passing, that statement is perfectly valid in java. :)
