【Regex】java應用Regex

標籤：ati   style   運算式   簡單   src   closed   one   string   正則表達   

一：簡單應用

 /**     *     * ‘     * &     * ‘     * &     * &     * ‘     * ‘     * ‘     * 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);    }

 

二：特例：“\”在java的Regex需要寫成“\\\\”

 /**     *      * &     *      * &     * &     * sources=sdcg\hde&xyz\dfa&&ad‘‘‘     * result=sdcghdexyzdfaad‘‘‘     *      * @param args     */    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);    }
