Depends on what kind of number you are expecting. If you are expecting an integer, try to parse it as an int. If it won't parse, it's not a number. You can do the same thing if you are expecting a FP number using Double or Float classes.

int myNum;
try {
myNum = Integer.parseInt(theString);
} catch (NumberFormatException e) {
// It's NOT a number
}
