Types of errors:
1. missing semicolons.  All statement must end with a semicolon ;
2. missing "" on string literals
3. missing {} on class or main method
4. missing () on method parameters.  E.g. System.out.print"" is an error but System.out.print(""); is correct
5. missing '.' on print() method calls. System out print(); error
