Java – Access Modifiers

Access Modifiers:

• Access modifiers are used to set permissions to access the Class and its members (variables, methods & constructors).
• Java supports 4 access modifiers
  • private
  • <package> or <default>
  • protected
  • public

Note: We cannot apply access modifiers to blocks(we cannot access because no identity)

public class Pro {             private int x;             private Pro()             {                       }             protected void fun()             {             }             static             {                         // Error:             } }

Understanding the Access Modifiers with simple diagram:

Representing the above diagram in table form:

private	Yes	No	No	No	No
<default>	Yes	Yes	Yes	No	No
protected	Yes	Yes	Yes	Yes	No
public	Yes	Yes	Yes	Yes	Yes
