Baby teeth also are primers for teaching your child good oral care habits. It is important to take care of your child's primary teeth. Even though primary teeth last only a few years, decay, cavities and infection can take its toll and may require expensive treatment to repair.
Here Integer is a name of a class in java.lang package and parseInt() is a method of Integer class which converts String to integer. If we want to enter a integer in a method or class using keyboard, then we have to use a method parseInt(). In this program we are going to calculate a area of a rectangle by using two classes named Rectangle and EnterValuesFromKeyboard. In the first class we have used two methods, show(int x, int y) and calculate().
The Integer.parseInt() java method is used primarily in parsing a String method argument into an Integer object. The Integer object is a wrapper class for the int primitive data type of java API.Eventhough the conversion of String to Integer object is a basic stuff, I am suggesting that we should have a mastery on it.
