question: public static Size sizeFromSettingString ( String sizeSettingString ) { if ( sizeSettingString == null ) { return null ; } String [ ] parts = sizeSettingString . split ( SIZE_SETTING_STRING_DIMENSION_DELIMITER ) ; if ( parts . length != 2 ) { return null ; } try { int width = Integer . parseInt ( parts [ 0 ] ) ; int height = Integer . parseInt ( parts [ 1 ] ) ; return new Size ( width , height ) ; } catch ( NumberFormatException ex ) { return null ; } }
target:  This parses a setting string and returns the representative size.
