What is difference between break and continue?

If you have try catch within the loop it gets executed completely inspite of exceptions.
Why goto statement should be avoided?
NOTE − Use of goto statement is highly discouraged in any programming language because it makes difficult to trace the control flow of a program, making the program hard to understand and hard to modify. Any program that uses a goto can be rewritten to avoid them.
