all instance data members will get memory each time. All students have its unique rollno and name so instance data member is good. But here, institute refers to the common property of all objects. So if we make it static, this field will get memory only once in a class area at class ...

In the preceding three code examples, IDENTIFIER is the name of the constant, and value is the variable’s initial value. For constant static variables and constant local variables, once value has been assigned by the variable initializer, it can never be reassigned. For constant instance variabl...
The class has no immediately enclosing instance and cannot directly reference enclosing type variables (6.5.5.1); enclosing instance variables, local variables, formal parameters, or exception parameters (6.5.6.1); or enclosing instance methods (15.12.3). A local class declaration may not use the ...

Since static methods don't operate on objects, you cannot access instance fields from a static method(静态方法不能操作对象,不能在一个静态方法中访问实例域). However,static methods can access the static fields in their class(静态方法可以访问类中的静态域). Here is an example of such a static...
