Testing if a string is NOT equal to...

Hi, I'm currently coding a Java program for a University coursework, and I'm a little bit stuck.

How do I find out if a string is NOT equal to a certain value? I know to test if it is equal, you use .equals, but I have no idea how to test if it's not equal to.

Use ! to negate a boolean expression, in this case !str1.equals(str2).
