Anoop KumarAssertions are generally part of Unit Testing.
You are going to test something which are are you expecting.
Like if you are expecting null then you can assert
assert i==null : "throw this message"
Assertions are bydefault disabled so adding assertions will not affect your run time. but when you need it.
just enable is by sending jvm parameter -ea. example : java -ea
Good one but very less used. everyone is using IDE with debugger. -
vikaskumar11233Assertion are used to verify the correctness of an invariant in the code. They should never be triggered in production code, and are indicative of a bug or misuse of a code path.
