报错
Illegal unquoted character ((CTRL-CHAR, code 9)): has to be escaped using backslash to be included in string value
查看是哪个字符导致的
System.out.println(new String( Character.toChars(9) ));
纠错
把这个字符替换掉即可。
str = str.replace( new String( Character.toChars(x) ),"");
我的code 9是制表符 导致的问题,.replaceAll(" ", " ")或.replace( new String( Character.toChars(9) ),"")替换掉即可,同理其他的 、 替换掉即可。
