java中替換字元以及斷行符號換行

//第一種方式import java.util.regex.Pattern;import java.util.regex.Matcher;...// 4 different combinaisonsPattern CRLF = Pattern.compile("(\r\n|\r|\n|\n\r)");Matcher m = CRLF.matcher(myString); if (m.find()) {  newString = m.replaceAll("<br>");}//第二種方式newString = myString.replaceAll("(\r\n|\r|\n|\n\r)", "<br>");

測試

import java.util.regex.Matcher;import java.util.regex.Pattern;public class StringTest {public static String sss(String myString){String newString=null;Pattern CRLF = Pattern.compile("(\r\n|\r|\n|\n\r)");Matcher m = CRLF.matcher(myString);if (m.find()) {  newString = m.replaceAll("<br>");}return newString;}/** * @param args */public static void main(String[] args) {String aaa="sdfsfdsfsdf\r\n,dsfsdfsdf\r\n";//aaa.replace("s", "x");String newStr=sss(aaa);System.out.println(newStr);}}
