java - Static methods inheritance and polymorphism -

how inheritance , polymorphism work static methods? explain proper output supposed here , how derived?

class { public static int get() { return 17; } } class b extends { public static int get() { return 42; } }    main  x = new b();  x.get();

the error message,

the static method get() type should accessed in static way

i think know how access in static way question class , sort of implied 1 or other values returned

in our program, have class definitions:

class { public static int get() { return 17; } } class b extends { public static int get() { return 42; } }

and somewhere else declare a x = new b();

what number call x.get() return?

the invocation return int value 17.

static methods not inherited.

static methods bound , invoked based on type of expression invoked on.

x.get();

where x of type a invokes a's implementation. note static methods don't need instance invoked.

these work well.

((a) null).get(); a.get(); ... public static somemethod() {} ... somemethod().get();

the message got warning, not error.
