if (subjectCode == (codes [i].substring (0,3)));
disciplineCodes.add (codes [i].substring (3,6));
The semi-colon at the end of the statement ends the if clause. It's not always returning true, but the next line always executes, because it's not part of the 'if' clause.
Use the equal() method to compare objects:
if ( subjectCode.equals( (codes[i].substring(0,3)) ) );
disciplineCodes.add (codes [i].substring (3,6));

Use the equal() method to compare objects:
if ( subjectCode.equals( (codes[i].substring(0,3)) ) );
if ( subjectCode.equals( (codes[i].substring(0,3)) ) );
Expanding on this some. With Objects, the == operator compares their memory locations, not their literal values. The equals() method in Object does the same thing. However, most classes (like String) override the equals() method to compare Objects based on their actual values, not their locations in memory.
