Access Modifiers in Java: How You and I Control Visibility
Access modifiers are used in Java to control how visible or accessible classes, interfaces, variables, methods, constructors, and data members are. When you and I write code, we often need to decide which parts should be accessible from other classes and which should stay private. That’s where access modifiers come in—they help us manage the scope and security of our code. By choosing the right modifier, we ensure that only the right parts of our program are exposed, improving both structure and reliability.
There are three types of access modifiers in Java. public, private, protected. If no access modifier is specified then it has a default access.
Object-oriented programming is used to set access modifiers, which control how accessible Java classes, constructors, methods, and other members are. We can control the scope or accessibility of these classes, methods, constructors, and other components using the access modifiers.
Access Modifiers in Java code example
- class A{
- protected void msg(){System.out.println(“Hello java”);}
- }
- public class Simple extends A{
- void msg(){System.out.println(“Hello java”);}//C.T.Error.
- public static void main(String args[]){
- Simple obj=new Simple();
- obj.msg();
