Asked In ::
The above code will produce error, as printValue() method is a non-static method, and has to be invoked by an object of the class. It should have been been invoked as a.printValue();
After you correct it, it will produce the output as 0 false 0.
The reason is that k is a global variable or you can say instance variable, and p is a static int variable, and note that global and static int variables need not be initialized before use. The default avlue for both is 0. On the other hand, istrue is a boolean variable, and default value of boolean variable is false.
Hence, the output is 0 false 0.
