Why we use IntegerParseInt in java?

Answer 1

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;

Answer 2

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.

Answer 3

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....
