Integer.parseInt is the way for the computer to turn a String value into an int data value.

For example:

String numberToBeParsed = ("15");
int parsedNumber = Integer.parseInt(numberToBeParsed);
console.printf("%s", parsedNumber);

This would give a result of 15.

it will take a string, whatever is in the string and turn it into a number so that we could use it.
