Beginner here, Name is Reagan.

My problem is that my code doesn't compile because of "break;". It says it is an unreachable code. I feel i am doing something wrong here, and i'm almost certain it has to do with the variable type.. not sure how to do this. This is from a method that calls for the users age.

My goal is to pass a string through my tryParseInt() method to test and make sure the input data is a integer, but keep it as a string type variable.

I'm creating a multidimensional String array to store user's data. I.e. Name; age; location.

Solution

  • break statement after a return statement is unreachable because the function exits before break statement is reached. Remove break; and your code should compile.
