Answer 1

If you have a String and you are sure that the only thing in it is a whole number without spaces, you can use Integer.parseInt(String) to convert it to an integer. This method will throw an exception if the string isn't just the number.

Answer 2

You cannot directly change or reference your String object to Integer type because there is no parent-child relationship between these two classes.

If you try to cast a String to a Integer in such a way, it will raise a ClassCastException.

String someValue = "123";
Integer intValue = (Integer) someValue; // ClassCastException Raise.

So if you want to change or reference a String Variable to Integer, you must use parsing techniques.

int intValue = Integer.parseInt(someValue); //this code will work for this.
