MiniMac is a virtual processor with a tiny but extendable memory and a tiny but extendable instruction set.Heres a screenshot of the MiniMac user interface:A screenshot of a computerDescription automatically generatedThe view panel on the right contains two lists (javax.swing.JList). The top list shows the contents of memory. The bottom list shows the program currently being executed. The control panel on the left contains three buttons (javax.swing.JButton). The first button prompts the user for a program to parse:A screenshot of a computer programDescription automatically generatedThe second button executes the program. The third button resets all memory cells to 0.These commands are duplicated under the Edit menu. The Help menu explains each command. The File menu contains the items: New, Save, Open, and Quit.The MiniMax memory is an array of integers:int size =32;Integer[] memory = new Integer[size];A MiniMax program is a list of instructions. An instruction pointer (ip) indicates the position in the list of the next instruction to be executed.GrammarHeres the instruction set grammar (note: ~ means followed by and all unquoted tokens are integers):Load ::= load ~ location ~ value // memory[location]= valueHalt ::= halt // terminates the programadd ::= add ~ src1 ~ src2 ~ dest // memory[dest]= memory[src1]+ memory[src2]mul ::= mul ~ src1 ~ src2 ~ dest // memory[dest]= memory[src1]* memory[src2]bgt ::= bgt ~ location ~ offset // if 0< memory[location] ip += offsetblt ::= blt ~ location ~ offset // if memory[location]<0 ip += offsetloop ::= loop ~ count ~ instruction // executes instruction count timesA block is a list of one or more instructions separated by semicolons and bracketed by curly braces:block ::={ ~ instruction ~ (; ~ instruction)* ~ }Executing a block sequentially executes each instruction in the blocks body.For example, the program shown in the screenshot computes kn, where n is stored in memory[0]. The base, k, is stored in memory[2]. In this case k =2, n was 7 and the result, 128, is stored in memory[1]. Memory[3] is the amount to decrement memory[0] each time the result is multiplied by k.DesignHeres the design of MiniMac:A diagram of a programDescription automatically generatedParserHeres a partial implementation of MiniMacParser.java. Note that it is a utility class (aka singleton), all of its methods are static.TestingImplement and test the following functions in MiniMax:Tri(n)=1+2+...+ n // stored in a file called triFib(n)= nth Fibonacci number // stored in a file called fibLess(n, m)=(n < m)?1:0//1= true and 0= falseLog(n)= m where 2m <= n and n <2m+1In each case the input, n, should be stored in memory[0] and the output, f(n), should be stored in memory[1].Hints1. The MiniMax is a publisher and the view panel is its subscriber. Each time memory is updated or a new program is set, MiniMax notifies its subscribers.2. The control panel is the action listener for its buttons. It navigates to the MiniMax and calls the appropriate procedure (execute and clear).3. Parsing is more complicated. The control panel must prompt the user for a file name, read the file (as a string), then pass the string to MiniMaxParser.parse(program). It then sets the MiniMax program to the parsers output, which causes a subscriber notification. Suggestion: ask ChatGPT how to read a text file in Java.4. Ask ChatGPT for a simple example of how to use a JList.
Please give me the instructions how to complete this and solve it to me completely. I really stuck on this and need help i want it correct not just a soloution from an AI because i already tried AI and chatgpt but it was incorrect. I will upvote if you answer correct and complete but if not i will give you a bad rate and diike. Thanks!
