Hi$,$ I really need help with this. Please completely answer it for me so i can rate you up vote otherwise i will down vote because this is really inportant for me$.$ Below i have attached a picture of what my output should look like and all the info. Also, i need to use IntelliJ to complete this so let me know how many files should i make And name them and each code for its file please. Ihave $3$ classes Instruction.java, MiniMacParser.java, MiniMac.java, and $4$ txt files as fib.txt$,$ less.txt$,$ log$.$txt$,$ tri.txt as tester code files. So please have the file bames as this and write and implement wverythibg for me$.$ I need the complete answer Thanks!

MiniMacMiniMac 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 ~ src$1$ ~ src$2$ ~ dest $//$ memory$[$dest$]=$ memory$[$src$1]+$ memory$[$src$2]$mul ::$=$ mul ~ src$1$ ~ src$2$ ~ dest $//$ memory$[$dest$]=$ memory$[$src$1]*$ memory$[$src$2]$bgt ::$=$ bgt ~ location ~ offset $//$ if $0$ memory$[$location$]$ ip $+=$ offsetblt ::$=$ blt ~ location ~ offset $//$ if memory$[$location$]<mtext\; id="EditorElement\_12964"></mtext><mn\; id="EditorElement\_12965">0</mn>$ 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 MiniMac: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 $2$m n and n $<mtext\; id="EditorElement\_14059"></mtext><mn\; id="EditorElement\_14060">2</mn>$m$+1$In each case the output, f$($n$),$ should be stored in memory$[0]$ and the inputs should be stored beginning in memory$[1].$Hints$1.$ The MiniMac is a publisher and the view panel is its subscriber. Each time memory is updated or a new program is set, MiniMac notifies its subscribers$\mathrm{.}2.$ The control panel is the action listener for its buttons. It navigates to the MiniMac and calls the appropriate procedure $($execute and clear$)\mathrm{.}3.$ 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 MiniMac program to the parsers output, which causes a subscriber notification.
