question: private void initializeSourceCodeMap ( String adaptedContent ) { sourceCodeWithLine = new LinkedHashMap < > ( ) ; int lineNumber = 1 ; StringReader sr = new StringReader ( adaptedContent ) ; BufferedReader br = new BufferedReader ( sr ) ; String line ; try { while ( ( line = br . readLine ( ) ) != null ) { sourceCodeWithLine . put ( lineNumber , line ) ; lineNumber ++ ; } } catch ( IOException ex ) { LOGGER . error ( "Error occured while initialize source code map " + ex . getMessage ( ) ) ; } }
target:  Initialisation of a local map that handles each source code line,  keyed by the line number
