Help with Java, need to complete missing parts

PROBLEM

The Motorola $68000$ family of CPUs is a Complex Instruction Set Computer $($CISC$)$; ie$,$ there are many formats, lengths, etc. We will consider only four instructions with a single addressing mode. An instruction in assembly language is written like

ADD.W D$3,$D$5$

That instruction says to add a "word" $(16-$bit$)$ value from data register $3$ to the value in data register $5.$ In machine language, the instruction looks like

Binary

Hex

$1101011001000101$

D$645$

The format of the instructions that we will consider is

$\backslash$table$[[$Assembly Language,Machine Language$],[$ADD$.s,$Dx$,$ Dy$,1101$ xxxsss$000$yyy$],[$SUB$.,Dx,Dy,1001xsss000yyy$
