Regular expression Java application Regular expression

One: Simple application

/** * *     '     * &     * '     * &     * &     * ' * ' * ' *     sources=sdcg ' hde&xyz ' Dfa&&ad '     * result=sdcghdexyzdfaad * *    /public static void main (string[] args) {        String regex= "' |&";        Pattern pattern=pattern.compile (regex);        String sources= "SDCG ' hde&xyz ' Dfa&&ad '";        Matcher matcher=pattern.matcher (sources);        while (Matcher.find ()) {            System.out.println (Matcher.group ());        }        String Result=matcher.replaceall ("");        System.out.println ("sources=" +sources);        System.out.println ("result=" +result);    

Second: Exception: "\" in Java regular expression needs to be written "\\\\"

 /*** * & * * & * & * sources=sdcg\hde&xyz\dfa&&ad ' * RESULT=SDCG Hdexyzdfaad "* *@paramargs*/     Public Static voidMain (string[] args) {String regex= "\\\\|&"; Pattern Pattern=pattern.compile (regex); String sources= "Sdcg\\hde&xyz\\dfa&&ad"; Matcher Matcher=pattern.matcher (sources);  while(Matcher.find ()) {System.out.println (Matcher.group ()); The String result=matcher.replaceall (""); System.out.println ("Sources=" +sources); System.out.println ("Result=" +result); }
