Java is considered very safe programming language compared to C and C++ as it doesn't have free() and malloc() to directly do memory allocation and deallocation, You don't need to worry of array overrun in Java as they are bounded and there is pointer arithmetic in Java. Still there are some sharp edges in Java programming language which you need to be aware of while writing enterprise application. Many of us make subtle mistake in Java which looks correct in first place but turn out to be buggy when looked carefully. In this series of java articles I will be sharing some of common Java mistake programmers make while programming application in Java. As I have said earlier every day we learn new things but we forget something equally important. This again highlight importance of code review and following best practices in Java. In this part we will discuss why double and float should not be used in monetary or financial calculation where exact result of calculation is expected.
