Switch Statements are not new for any Programmer, it is available in C, C++, Java and in all major programming language. The switch statement in Java allows you to a clear, concise, and efficient multiple-branch statement without lots and lots of messy if-else statements. But Java Switch and case statement have a limitation, you cannot use String in them. Since String is one of the most used classes in Java, and almost every program, starting from Hello World to a complex multi-tier Java application uses them, it makes a lot of sense to allow them in the Switch case. In Java 6 and before, the values for the cases could only be constants of integral type e.g. byte, char, short, int, and enum constants. If you consider Autoboxing then you can also use the corresponding wrapper class like Byte, Character, Short, and Integer.
