"if" statement can be used to compare about objects. for example: String compare to String. But for "switch" statement, it can only compare about int, byte,char, long, short, and enum Source: CoolInterview.com

In if statement we can use relation operator such as(<,>,<=,>=) and also use boolean.
Here in if statement if we use nested if statement then the first condition is false then they go to next 'else-if' .
But in switch we can we can just the value and direclty go to that 'case'.
