Java what makes a method static

Static methods are often utility methods found in System, Wrapper and Collections classes that are used because they can be more efficient. They can be employed by different classes without having to create an instance, which can sometimes make the difference. Methods are created as static when object state has no effect on their behavior because they depend only on their own parameters.

Static methods can also be defined in interfaces in Java 8 and subsequent versions. All instance methods should share a specific piece of code although you could still have an instance method for that.

You want to call method without having to create an instance of that class. Your method is not using any instance variable, and the code does not depend on instance creation.

Note: main method is static, since it must be accessible for an application to run, before any instantiation takes place. Lets learn the nuances of the static keywords by doing some excercises! Run the code as, java Demo.

Step 4 It is possible to access a static variable from outside the class using the syntax ClassName. Observe the output. The static block is a block of statement inside a Java class that will be executed when a class is first loaded into the JVM.

A static block helps to initialize the static data members , just like constructors help to initialize instance members. Skip to content.
