please provide Java code for this project

This project will be to write an interpreter for a minimal form of Julia. This minimal form of Julia has only 1 data type, integer, and the only identifiers are single letters.

The interpreter will parse a Julia program and build some intermediate data structures. These data structures will then be interpreted to execute the program. All tokens in this language are separated by white space. The parsing algorithm should detect any syntactical or semantic error. The first such error discovered should cause an appropriate error message to be printed, and then the interpreter should terminate. Run-time errors should also be detected with appropriate error messages being printed.
