Edit Question
Title
Body
So I'm learning java, and I have a question. It seems that the types int , boolean and string will be good for just about everything I'll ever need in terms of variables, except perhaps float could be used when decimal numbers are needed in a number. My question is, are the other types such as long , double , byte , char etc ever used in normal, everyday programming? What are some practical things these could be used for? What do they exist for?
