![]() ![]() ![]() One common example of a static method in Java is the main().Īny static method belongs to a class and not the object. Such a situation demands creating a static method. We might require situations where we need to perform certain operations that are not dependent on any class instance creation. When we need a variable's value same for all the class objects, we declare a variable static.We can use static variables when we want to have a variable that illustrates something about the class itself.A Java program initializes a static variable before the creation of any class object.It allows us to create a single copy of the variable utilized and shared with other class instances.Variables declared as static are common to all the class instances.Note that, when we call the disp() method from within the main(), the institute value remains the same throughout. Then we are printing the institute value from within the disp() method. We also have a constructor that is fetching the student-name and roll number. Within the Stud class, we have created a static String-type variable institute. Here is a code snippet showing the use of static variables. We can create static variables at the class-level only. All the class instances share this variable so that the data becomes sharable to all the classes. Programmers declare the static variables by placing the static keyword followed by the variable name. Static variables are those variables that have a unique copy and are globally accessible by any object. staticmeth() method is used before creating the object of the Main class. Now, within the main() you can note that, without creating the class object, you have called the static method. Here we have declared staticmeth() as static inside which we have placed a message. (" This public method needs to be invoked by creating the object of the class. (" We can create the static method without creating the object of the class. Here is a simple example showing the use of the static keyword. Another significant fact about static members is - once a member is declared static, programmers can access those members before creating the object of the class. For creating a static member, precede the declaration with the static keyword. Programmers use this non-access modifier to share the same method or variable of a given class. Programmers use the static keyword before the method, variable, and class name. It means that you can access or use any statically declared program element without object creation. In Java, static members belong to the class rather than their specific objects. This article will talk about the Static keyword in detail. Programmers use it with various other elements of programming. Among them, the static keyword plays a vital role in memory management. In total, there are fifty-seven keywords in Java. The entwinement of keywords with variables in Java plays a significant role. ![]()
