In Java, class is an example of Encapsulation. A class wraps code (method) and data(variables) together.

• This concept ensures that data members of a class are always hidden from other classes.
• We can only access those data members using the methods.
• Encapsulation is also known as data-hiding as it prevents data from being accessed by the code outside the class.

			
					public class book {
    private String name;
    private String authorName;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getAuthorName() {
        return authorName;
    }

    public void setAuthorName(String authorName) {
        this.authorName = authorName;
    }
}

			
	

			
	
			

		
	

Advantages of Encapsulation

• We can make read-only and write-only classes using Encapsulation.
• We can achieve data hiding.
• The encapsulated classes are better for unit testing.
• It is easy and fast.
• We have control over data.
