Why non-static variable cannot be referenced from a static context in Java
The error non static variable cannot be referenced from a static context in Java is mostly faced by the beginners at the time of compilation of Java program. The reason to occur this error is that they use a non-static member variable in the main() method. Because the main() method in Java is a static method and it is invoked automatically, we need not to create an object to invoke it. To understand the error, first we should understand the static and non-static method in Java.
Static Method
In Java, public methods belong to an instance of class but if we talk about static method, they belong to a class not to an instance of a class. There is no need of creating an instance of the class to invoke a static method. The static member can access only the static data member and can change its value.
Non-static Method
All the methods without having static keyword before method name are referred to as Non-static methods. There is no need to create an instance of the class for accessing the static method and static variable. The non-static methods are used dynamic or runtime binding. Unlike static method, we can override the non-static method.
Let's create a Java program and generate the same error.
