Strings Values with Switch Statements

Before Java SE 7, We can use integer or byte value in switch statement. In Java SE 7, string value can be enabled in switch statement.

Binary Literal can be represented directly instead of hexadecimal.

we can insert underscore(_) as deliminator in number. It can not be used at starting and ending.
