Java removes the 0 in front of the string

Best practices: Using regular

String str = "000000001234034120"= Str.replaceall ("^ (0+)", ""); System.out.println (NEWSTR);

Package Com.exmyth.test.string; Public classStrTest04 {/** * @param args*/     Public Static voidMain (string[] args) {//TODO auto-generated Method StubString str ="00001102";//String for testing        intLen = Str.length ();//gets the length of the string        intindex =0;//pre-defined position of the first non-0 string        CharStrs[] = Str.tochararray ();//Convert a string into a character array         for(inti =0; i < Len; i++) {            if('0'!=Strs[i]) {Index= i;//find a non-0 string and jump out                 Break; }} String Strlast= str.substring (index, Len);//Intercept StringSystem. out. println (Strlast);//Get Results Strlast    }}
