Semi colon expected?

It is telling my that a semi colon is expected in between the second "%lf" and the comma before the "x". Here is the code segment: 

 public String toString() {
        return "%lf, %lf", x, y; 
    }

I am trying to return the string "(X, Y)"

Any ideas? Many thanks!

Comma-separated variables cannot be recognized as a valid Strings in Java.

It appears you are using format specifiers similar to those found in C/C++'s printf function.

Assuming that x and y are valid floating point values you can use

return String.format("%f, %f", x, y);

to format the output String

if you are trying to access multiple values, just use two different functions to return the values. if you want to return both values as a single string, use concatenation.

return "%lf, %lf", x, y;

is not a String

return "%lf, %lf, x, y";

or 

return "%lf, %lf" + x + y;

is a String.

I don't know what you are trying to do. You can't return multiple values as the method is declared String. Try as follows:

return "%lf, %lf"+x+y;

for a literal contatenation.

return String.format("%f, %f", x, y);

will use a format string.
