Parsing is very important since the input from the user is not in the form of ints but in a String, therefore, you have to parse the String containing the number into a primitive data type.
i.e.
String num = "49";
int realNum = Integer.parseInt(num); // puts 49 into realNum;
We use "Integer.parseInt" to convert a string into a integer value. If the the string is not an integer, it will throw a NumberFormatException.
it is used for taking the input from the user..........java reads it as the string...so integerparseInt is used to taking the input and convert it to the string....
