What is the difference between static and nonstatic member with example in java?
It depends on whether the member is a static variable or a static method of the class.A non-static member variable is an instance variable. That is, each instance of the class has its own independent set of instance variables.A static member variable is not associated with any one instance of the class, and exists even when there are no instances of the class. As with all static variables, it exists for the entire duration of the program.A non-static member method is an instance method, thus the method automatically inherits a this pointer.A static member method does not inherit a this pointer, but it does have private access to to the class. Thus specific instances can be passed to a static method if necessary.Static members can be thought of as being common to all instances of a class, rather than a specific instance, even though no instances are actually required in order to make use of them.
How do you invoke static methods?
if some method is static, then you can not call that method through the oobject of that class. but the name of the class. let us see a example: class Test { int a; int b; static void show() { System.out.println("we are in show"); } } class Main { public static void main(String args[]) { Test t=new Test(); t.show();\\thiss is an erroraneous code. because, the method "show()" is static. Test.show();\\this is correct } Arnas Sinha
