如何在Java中打印转义字符？

一种方法是：

public static String unEscapeString(String s){    StringBuilder sb = new StringBuilder();    for (int i=0; i<s.length(); i++)        switch (s.charAt(i)){ case 'n': sb.append("\n"); break; case 't': sb.append("\t"); break; // ... rest of escape characters default: sb.append(s.charAt(i));        }    return sb.toString();}

然后你跑了

System.out.print(unEscapeString(x))
