Question:I need to have my Java program take input to read palindromes. So far, I have the following code:
/**
* A program class (firstsubroutines)with two subroutines (myConversion and myReverse).
* The program tests if the user input word is a palindrome.
* The subroutine myConversion converts the input string to lower case, and removes any non-letter characters.
* The subroutine myReverse takes the string and reverses it.
* The main routine will compare the user input string with the reverse and see if it is a palindrome.

public static void main(String[] args) {

String myInput;

System.out.println("ITS A PALINDROME");

String reverse = "";

I have the TextIO.java, but what do I need to do to be able to get user input? TextIO.java is what I am supposed to use. I use NetBeans and the input must be able to be inputted in NetBeans by the user. Why is this not working? My code runs without error, but nothing appears so that the user can provide input.
