Update 2 files - file exclusion

• /FreqTableExampleOriginal.java
• /IntListVer2.java

Summary by Bito

• 5 new Java files added: AirlineProblem, BinaryConverter, FreqTableExampleOriginal, IntListVer2, and PrimitiveParameters
• AirlineProblem.java contains multiple critical bugs: null check using '!= 0' instead of '!= null', return type mismatch (returns 0 instead of true), and loop condition 'pos == 1' instead of 'pos == -1'
• BinaryConverter.java has syntax errors: invalid operator '/==' instead of '/=' on line 158, and bitwise OR '|' instead of logical OR '||' on line 182
• IntListVer2.java contains syntax errors: double assignment operator '==' instead of '=' for DEFAULT_CAP constant, duplicate iSize variable declaration, incomplete increment 'iSize+' instead of 'iSize++', and missing method body
• PrimitiveParameters.java has multiple syntax errors: double equals '==' instead of '=' for variable initialization, double asterisk '**' instead of '*' for multiplication, and missing semicolon after assignment
• FreqTableExampleOriginal.java appears syntactically correct with proper exception handling and file I/O operations
• AirlineProblem.java line 112 has syntax error: 'partners.size(l)' with invalid parameter 'l' instead of empty parentheses
• AirlineProblem.java line 116 has incomplete method call: 'partners.contains()' missing required String argument
