In this tutorial, we will learn about the Java Access Modifier, its types, and how to use them with the help of examples. In Java, access modifiers are used to set the accessibility (visibility) of classes, interfaces, variables, methods, constructors, d
Variables and methods can be declared without any modifiers, as in the following examples: String version = "1.5.1";booleanprocessOrder() {returntrue; } Private Access Modifier - private: Methods, Variables and Constructors that are declared private can only be accessed within the declared class...
Public is the most well known of the Java keywords. Public is also the easiest of the Java access modifiers because of its nature. A variable or method that is public means that any class can access it. This is useful for when the variable should be accessible by your entire application....
Java providesfour access modifiersto set access levels for classes, variables, methods andconstructorsi.e.public,private,protectedanddefault. These access level modifiers determine whether other classes can use a particular field or invoke a particular method. 1. Access Modifiers Let’s quickly compare...

Now, we’ll see some simple code examples to better understand the subject. First, let’s create anEmployeeclass containing a couple ofprivateinstance variables: publicclassEmployee{privateString privateId;privatebooleanmanager;//...}Copy In this example, we marked theprivateIdvariable asprivatebecau...
people say that private accesss-modifiers increase your code security, but if you compile your code into a .class format. wouldn't people not be able to see your codes anyway? and why don't people use all public access-modifiers to make their life easier? pardon me if this is a stupid...
Access level modifiers determine whether other classes can use a particular field or invoke a particular method. There are two levels of access control: At the top level—public, or package-private (no explicit modifier). At the member level—public, private, protected, or package-private (no...
