If you can post your code we can point out what is triggering the error and give an explanation as to why it throws the error.

It likely means you're trying to assign a String value to a variable that is declared as another Type.

Like so:

public class Employee {

    String name;

}

Employee employee1 = "Bob";

Or maybe something like:

int guess = //some method or statement that collects input from the user at the console here....

...but then you never cast it to an integer, so the input came back as a String, even though you meant to store an integer or something.

So I'd check the call stack, find out what the line was that you're having trouble with, and just look at what that line might be trying to do, versus what you really want it to do.

Without seeing your code, did you do something like this with your integer & string?

int i = Integer.parseInt(myString);
