Demonstrate Private access modifier in Java
The data members and methods of a class can be accessed only from within their declared class if they are specified with the private access modifier. The keyword private is used to specify this modifier.
A program that demonstrates the private access modifier in Java is given as follows:
Example
class A {
private int a = 6;
public void printA() {
System.out.println("Value of a = " + a);
}
}
public class Demo {
public static void main(String args[]) {
A obj = new A();
obj.printA();
}
}Output
Value of a = 6
Now let us understand the above program.
The class A has a private data member a that can be accessed only from within the class. The method printA() displays the value of a. A code snippet which demonstrates this is as follows:
class A {
private int a = 6;
public void printA() {
System.out.println("Value of a = " + a);
}
}In the main() method in class Demo, an object obj of class A is created. Then printA() method is called. A code snippet which demonstrates this is as follows:
public class Demo {
public static void main(String args[]) {
A obj = new A();
obj.printA();
}
}
