Encapsulation Explanation With Example In JAVA: Now we will explain the concept of Encapsulation with example. Example 1:In the below example, we will set two fields as private name and email in class UserDetails. So these fields can only be access within this class and no outside class can...
In above example all the three variables (or data fields) are private(see:Access Modifiers in Java) which cannot be accessed directly. These fields can be accessed via public methods only. VariablesempName,ssnandempAgeare made hidden data fields using encapsulation technique of OOPs. Advantages of...
In this tutorial, we shall learn the intuition and realization of encapsulation in Java language with example programs. The below diagram gives an idea about Encapsulation in Java Points to be made from the above diagram are Variables (in the example: height, weight, bmi) are declared private,...
An object's encapsulation allows it to hide its data and methods. It is one of the fundamental principles of object-oriented programming. Java classes encapsulate the fields and methods that define an object's state and actions. Encapsulation enables you to write reusable programs. It also enable...

Java 中的抽象 数据抽象是一种仅向用户显示基本细节的属性。不重要或非必要的单元不会显示给用户。例如:汽车被视为一辆汽车,而不是其各个部件。数据抽象也可以定义为仅识别对象所需特征而忽略不相关细节的过程。对象的属性和行为将其与类似类型的其他对象区分开来,并且还有助于对对象进行分类/分组。
MyClass.java:5: error: name has private access in Person System.out.println(myObj.name); ^ 2 errors Instead, we use thegetName()andsetName()methods to access and update the variable: Example publicclassMain{publicstaticvoidmain(String[]args){PersonmyObj=newPerson();myObj.setName("John"...

To work with such abstract actors, we only need to know about the public APIs that we will use. We need not to care about how they perform their work. For example, in the previous example ofReportWriter, we have defined thewriteReport()method that clients must use to generate the report...
Such freedom is a convenience in programs. For example, the previous line has been useful to produce the following output: Tim is a male student. However, this freedom is also a liability. As an example, let's assume that perhaps by mistake, the name of a student object gets modified in...
