Why a static member method can access only static members in java?
Because, the keyword static signifies the fact that the method or variable that is qualified using the static keyword is not attached to any object of the class. Therefore we cannot instantiate the class and use the object to reference to access it. The only option we have is to use the class name to directly access them
Will JVM execute static methods by default like static variables in java?
No. Static methods are invoked by using the name of the class instead of the name of an instance of a class. Example: public class Test { public static void methodA { // do something ... } public void methodB { // do something else ... } } A program could use methodA by simply calling it using the class name: // call the static method Test.methodA(); To use methodB(), a program would have to first create an instance of the class then call the method: // call the non-static method Test t = new Test(); t.methodB(); Note that you can call methodA from the instance: // call the static method Test t = new Test(); t.methodA(); However, this is considered bad practice. And you cannot call methodB at all using the class name: // can't do this - compile error Test.methodB();

How do you sum up numbers from 1 to n?

Tell about static method?
in java a method is said to be static if 'static 'keyword is used before the method name . foe ex.- static void show(){ ........ } this method has the following property-- 1. it can invoke only a static method. 2. it can't be reffered using keyword 'this','super'. 3.static method can access only a STATIC MEMBER VARIABLE or STATIC CLASS VARIABLE . 4. there should not be static & non static version of a nethod in a class . 5.static method can be used before the creation of d object of dt class.
