Exceptions are errors/problems: Some examples: String str = null; System.out.println(str.length()); -> an empty String has no length() int x = 3; int y = 0; System.out.println(x/y); -> dividing by zero Having a Scanner scan: int x = scan.nextInt(); If you don't enter an integer you will get an error message. If you want to open a file which does not exist... With exception handling you can catch this exceptions and decide what to do. Your program will not just crash.

Exceptions are just errors in your code
