我有一个类似 C:users Empenindex.html 的字符串,想要用 替换 " 。
str= str.replace("", "\");
。但日圆会不断建议我在替换方法中添加参数。
任何帮助都将不胜感激。
您需要逃离斜线字符 :
str = str.replace("\", "\\");
您需要逃出您的 。 请使用 字符来逃出 。 是逃避 和 < code> 所必须的 。
str.replace("\", "\\");
String str="C:Users empindex.html";
str = str.replace("\", "\\");
System.out.println(str);
试试这个
str = str.replace("\", "\\");
因为“ ” 否定了语言中具有特殊意义的符号的效果 。
