Thread: parseInt method

Back in the good old days before the Scanner class all input was in the form of Strings. If user needed to input a numerical value then your code would read the input as a String and parse it using the parseInt method. There are still many occasions when that method is useful but I can't be bothered to think of any.

What better time than any to become acquainted with the java API docs. Presuming you are referring to the Integer class method, than:
Integer (Java Platform SE 7 )

Reading user input from a JTextField would be an obvious one. JTextFields return Strings. You probably could wire a Scanner up to a JTextField somehow if you really wanted to, but that would be like killing a fly with a rocket launcher.
