java and assemble

I have to make an assembler simulator of our SIC/XE computer. The main features I want in it are - The object program must have the Header, Text, Modification, End records Implement the two passes of the SIC/XE Assembler using Fig 2.4 algorithm Implement assembler internal tables like OPTAB and SYMTAB Consider different type of addressing for your SIC/XE assembler simulator such as PC-relative/Base-relative addressing, indirect addressing, immediate addressing, extended format, index addressing, and also register-to-register instructions. Any language or combination of languages is preferred
