Java Code: I am using the code below but it will not compile.

PROGRAM:

using System; //import java.util.Scanner; //Create the class that would perform the simulation. public class Simulator { public static void main(String[] args) { //list of SML instructions const int READ_INS = 10; const int WRITE_INS = 11; const int LOAD_INS = 20; const int STORE_INS = 21; const int ADD_INS = 30; const int SUBTRACT_INS = 31; const int MULTIPLY_INS = 32; const int DIVIDE_INS = 33; const int BRANCH_INS = 40; const int BRANCH_NEG_INS = 41; const int BRANCH_ZERO_INS = 42; const int HALT_INS = 43; //variabes for storing the instruction and its details. int accumulator; int instructionCounter; int op_oprnd; int op_Code; int instructionRegister; //simpletron memArray int[] memArray; //number of instructions entered in memArray int index = 0;

/* Method to run the simpletron simulator*/ }
