We can use this class by making object of the scanner class. For Example: Scanner s=new Scanner(System.in); Scanner class is a predefined class which is defined in java.util package. That’s why to use Scanner class, we have to import java.util package. CODE Import java.util.*; Here java is main package and util is a sub package created inside. Package, sub package and class is always separated with dot (.). Pre-defined Methods Of Scanner Class Code/Output Oriented Approachobject As we know, Java is an object oriented language. It supports various object oriented concepts that are as follows: Object and Classes Inheritance Polymorphism Abstraction Encapsulation Chapters: 0:00 Core Java 0:06 Topics 0:56 Taking Input from Console-Scanner Class 1:24 Example of Console-Scanner Class 2:08 Import Java Util 2:25 Table of Function Method 3:24 Program of the Output 5:00 Object Oriented Approach 7:00 Classes & Object 8:06 Functions/Methods 9:13 Variable-Local Variable 10:23 Variable-Instance Variable 11:22 Variable-Class Variable 12:42 Questions #corejava #topics #console-scannerclass #importjavautil #functionmethod #programoftheoutput #objectorientedapproach #classes&object #functions/methods #localvariable #instancevariable #classvariable #testprep #ugcnet #doorsteptutor #examrace
