如何替换字符串中的 \0 (NUL)?
String b = "2012yyyy06mm"; // sth what i want
String c = "2\0\0\0012yyyy06mm";
String d = c.replaceAll("\\\\0", ""); // not work
String e = d.replace("\0", ""); // er, the same
System.out.println(c+"\n"+d+"\n"+e);
String bb = "2012yyyy06mm";
System.out.println(b.length() + " > " +bb.length());
上面的代码将在控制台中打印 12 > 11。哎呀,怎么了?
String e = c.replace("\0", "");
System.out.println(e); // just print 2(a bad character)2yyyy06mm
