Fuzzing in software testing means changing the program inputs so that you create different inputs in the hope of uncovering software bugs. Fuzzing is nothing more than supplying random input to a program or unit. There are two types of fuzzing: generation and mutation based fuzzing. Mutation Based Fuzzing This type of fuzzing is very…
Very Busy Expression Analysis Consider the following program: Note that a*b is used twice in the program. Moreover, we can compute a*b value at point A in the program.

Why do we need dynamic method binding? Can we simply bind any method statically at compile time in Java? No! Let us see this example: The interesting part is that we don’t know the exact type of a variable in the program in run time. For example, check this program: But we can bind private/static/final…
