Tutorial: Change the user input to integer

In this program we are going to calculate a area of a rectangle by using two classes named Rectangle and EnterValuesFromKeyboard.

Tutorial Details:

Isn't it a very tedious job to enter the values each time before the compilation in the method itself. Now if we want to enter an integer value after the compilation of a program and force the JVM to ask for an input, then we should use Integer.parseInt(string str).

As we know that JVM reads each data type in a String format. Now consider a case where we to enter a value in int primitive type, then we have to use int x = Integer.parseInt("any String") , because the value we have entered is in integer but it will be interpreted as a String so, we have to change the string into integer.
