What does this line "int age = Integer.parseInt("30"); " do? In particular "Integer.parseInt("30")" ?
Hello, this pretty much turns a string type variable into a int. So in your example it is turning it is creating an integer variable from the string "30" so it return an int of 30. With that being said wed use it to be able to use Integer methods on the int variable.
