Here is my attempt so far. It's is not working like the instructions above ask.
public class MixedCase
* @param args the command line arguments
public static void main(String args)
Scanner input = new Scanner (System.in);
System.out.print("Please enter a string: ");
a = input.nextLine();
for (char i = 0; i < a.length(); i++)
if ((Character.isUpperCase(a.charAt(i))) && Character.isLowerCase(a.charAt(i)))
System.out.print("This string has both lower and upper case characters.");
System.out.print("This string does not have both lower and upper case characters.");
Why do you think that? Java char is a numeric 16 bit integer type, perfectly OK, and converted to int by Java whenever needed. Did you test that before posting? It may be an odd choice, but its not wrong.
It certainly won't fix his (unspecified) problem, which is caused by the logic being way off - eg the boolean expression on line 17 will alwyas return false, which presumably is not what he intended.
