Java Run Eclipse Test Cases Would Cause Two Methods Produce Error Code Four Methods Two Er Q43856772
In Java run through Eclipse, What test cases would cause two ofthese methods to produce an error?
* This is code for four methods, two of which have errors.
* You should create a second file calledTestThisClassTest.java
* which provides at least three test cases for each method.
* The methods with errors should be left with errors, but the
* code should expose the problem with them.
