if you want to allow outside world to access these variables is better creating a getter and setter e.g. We cannot have more than one public class in the same source file.

Let's go step by step: First, you need to understand What is encapsulation and why is it used.? Data Hiding In Java Code re-use: If an object already exists (perhaps written by another software developer), you can use that object in your program.

Previous page: Object-Oriented Programming Concepts Next page: What Is a Class? Code change suggested by @Subhrajyoti Majumder is the correct one. In that code, calculating the heading with the method call util.heading( myHouse, coffeeShop ) didn't clearly indicate the calculation's direction. have a peek at these guys For this reason, encapsulation is also referred to as data hiding.

Yes, that is possible if we encapsulate Loan creation logic in one method say createLoan() and client code call this method and this method internally create Loan object.

Encapsulation also helps to write immutable class in Java which is a good choice in multi-threading environment. 5. Check the answer for solving the problem. Often that definition is misconstrued to mean that the data is somehow hidden.

if one leaves the school, this doesn't mean, every other student (object of student class) should leave the school too. Note that encapsulation guarantees neither data protection nor information hiding. Encapsulation is the concept of having your class variables as private, so that no one can directly play with your data members from outer world. Example is given below // Employee class public class Employee { public static int empid; public static String empname; public static void main(String[] args) { System.out.println("print employe details:"+empid+" "+empname); } //

Encapsulation can be described as a protective barrier that prevents the code and data being randomly accessed by other code defined outside the class. Encapsulation is a technique, which is mentioned in second paragraph of my answer, and its example is given at end.
