I want to split this file by instructions and values like String = "LOAD" int = 20 and remove line numbers.

Answer 1

you need to read this file line by line as described for example here How can I read a large text file line by line using Java?

then for each line you need to do smth. like

String[] split = line.split("\\s+");

in split array you will have your values for example {"2", "STORE", "200"}

just parse or perform Integer.valueOf() for those that are actually numbers.
