### Question:
StringScanner { public static String substringAfter(String string, String after) { int index = StringScanner.findString(string, after); if (index==-1) { return ""; } else { return Str.slc(string, index+after.length()); } }  static boolean isDigits( String input ); static String[] split( final String string,
                                  final char split, final int limit ); static String[] split( final String string,
                                  final char split ); static String[] splitByChars( final String string,
                                         final char... delimiters ); static String[] splitByCharsFromToDelims( final String string, int from, int to,
                                         final char... delimiters ); static String[] splitByCharsFrom( final String string, int from,
                                                     final char... delimiters ); static String[] splitByWhiteSpace( final String string
                                         ); static String[] splitByDelimiters( final String string,
                                              final String delimiters ); static String[] splitByCharsNoneEmpty( final String string, final char... delimiters ); static String removeChars( final String string, final char... delimiters ); static String[] splitByCharsNoneEmpty( final String string, int start, int end, final char... delimiters ); static float parseFloat( String buffer, int from, int to ); static float parseFloat( String buffer ); static double parseDouble( String buffer, int from, int to ); static double parseDouble( String buffer ); static int parseInt( String buffer, int from, int to ); static int parseInt( String buffer ); static long parseLong( String buffer, int from, int to ); static long parseLong( String buffer ); static short parseShort( String buffer, int from, int to ); static short parseShort( String buffer ); static short parseByte( String buffer, int from, int to ); static short parseByte( String buffer ); static int findWhiteSpace(String buffer); static String substringAfter(String string, String after); static String substringBefore(String string, String before);  }### Answer:
@Test public void testSubStringAfter() { final String substringAfter = StringScanner.substringAfter("love :: rocket", " :: "); ok |= substringAfter.equals("rocket") || die(substringAfter); }
