<h2>Option D: a call to a private method of the superclass</h2>
Explanation:
Option a: a method with the "same signature" is allowed in the subclass. There will not be any confusion because the object which is trying to call the method will decide whether to call the sub class or super class.
Option b: a call to a super class constructor is possible because, when you create an object of sub class automatically the super class constructor will be called. Even the sub class constructor can call the super class constructor explicitly.
Option c: A subclass can create method that's not defined by the super class
Option D: a private method is private inside the class and hence even the object of that class cannot access.
Answer:
-32 to +31
Explanation:
6 bit 2s complement representation will be of the form b1b2b3b4b5b6 where each bit is either 0 or 1.
The largest positive number that can be represented using this scheme is 011111
Translating this to decimal this is 1*2^4 + 1^2^3 + 1^2^2 + 1^2^1 + 1^2^0
=16 + 8 + 4 + 2 + 1 =31
The smallest negative number that can be represented using this scheme is 100000
Translating this to decimal = -1 * 2^5 = -32
So the range of decimal values that can be represented is -32 to +31.
