parse.Int();

You can use the method Integer.parseInt() to convert a string into an integer value. You have to remember that in programming the value: 10 and "10" are no the same, they might look like they are the same thing but if you were to make some basic math calculations you will get an error from the console. if you try to do

String number = "10";
System.out.println(number*10);

You would get some kind of error since the first value is a string and not a number value. You have to take into consideration that the string named number has a value that right now looks like a number but a string could be anything, just imagine trying to do this

String number = "cake";
System.out.println(number*10);

See? Imagine you were to type the word "cake" into your calculator and then trying to multiply it by 10 it doesn't make sense. But if instead you were to do:

String number = "10";
int newNumber = Integer.parseInt(number);
System.out.println(newNumber*10);

You would get the integer value 100 printed to the console.
