Concept explainers
This type of method cannot access any non-static member variables in its own class.
- a. instance
- b. void
- c. static
- d. non-static

Static methods cannot be accessed by any non-static member variable within a class
Hence, the correct answer is option “C”.
Explanation of Solution
Static method:
Static is an access modifier which cannot be accessed and is applicable on block, variable, methods, and nested classes. Static keyword is added while declaring the block or variable or methods. A static member can be accessed before any objects of its class are created, and without even using the reference to any object.
Explanation for incorrect options:
a. Instance:
Instance variables are declared without the static keyword and are present outside any method declaration.
Hence, the option “A” is wrong.
b. Void:
It describes the return type of the method, where void means the method has no return value.
Hence, the option “B” is wrong.
d. Non-static:
Non-static variables can be accessed by any member variable.
Hence, the option “D” is wrong.

- Specifications: Part-1Part-1: DescriptionIn this part of the lab you will build a single operation ALU. This ALU will implement a bitwise left rotation. Forthis lab assignment you are not allowed to use Digital's Arithmetic components.IF YOU ARE FOUND USING THEM, YOU WILL RECEIVE A ZERO FOR LAB2!The ALU you will be implementing consists of two 4-bit inputs (named inA and inB) and one 4-bit output (named out). Your ALU must rotate the bits in inA by the amount given by inB (i.e. 0-15).Part-1: User InterfaceYou are provided an interface file lab2_part1.dig; start Part-1 from this file.NOTE: You are not permitted to edit the content inside the dotted lines rectangle. Part-1: ExampleIn the figure above, the input values that we have selected to test are inA = {inA_3, inA_2, inA_1, inA_0} = {0, 1, 0,0} and inB = {inB_3, inB_2, inB_1, inB_0} = {0, 0, 1, 0}. Therefore, we must rotate the bus 0100 bitwise left by00102, or 2 in base 10, to get {0, 0, 0, 1}. Please note that a rotation left is…arrow_forwardSolve this "Do not use AI tools.
