I want my program to read in an arithmetic statement consisting of integers and the operators "+" and "-," and outputs a regular LMC assembly language program to a file that can then be assembled by the LMC assembler and run on the LMC.

For example, if the input statement (one line only) is
5 + 3 - 6 + 2

The output should be LMC assembly language program:
.LMC
LOAD NUM1
ADD NUM2
SUB NUM3
ADD NUM4
PRINT
STOP
.DC NUM1 005
.DC NUM2 003
.DC NUM3 006
.DC NUM4 002
.END

Ignored whitespace between characters in the arithmetic expression are ignored and assume that all of the integer values are positive.


Please help.

Please don't post the same quetion to multiple forums. It just wastes people's time. Since there's a reply in this copy, I'll leave that one open and close this one -- although this isn't really an advanced Java topic.
