Java-从字符串评估字符串

问题描述

在我的Java代码中，我有以下代码段:

in my Java code I have this snippet:

String str = "\\u9601";

但我希望它是

String str = "\u9601";

代表宽字符.

有没有办法做到这一点?

Are there ways to do this?

请帮助.预先感谢.

补充:

很抱歉回答这个问题.

System.out.print("\u9601"); //this will display a Chinese character

我当前正在请求一个以JSON响应的网页(URL).如果使用"System.out.print"转储到控制台，则JSON将显示为6个可见字符 \ ， u ， 9 ， 6 ， 0 和 1 ，但日食中不包含汉字.

I am currently request a webpage(URL) which response with a JSON.If dumped to Console using "System.out.print", the JSON will turn out to be 6 visible characters \, u, 9, 6, 0 and 1,but not a Chinese character in eclipse.

所以实际上我想要的是有API可以将"\\ u9601"转换为"\ u9601"，因为我不能硬编码内容的Java源来自网站.

So actually what I want is are there APIs can convert "\\u9601" to "\u9601", since I can not hard code the Java source for the contents comes from website.

推荐答案

如果您希望它是String str = "\u9601";，请保持这种方式！

If you want it to be String str = "\u9601";, keep it that way!

根据更新后的问题进行编辑

Apache Commons Lang API中的nofollow> StringEscapeUtils.unescapeJava 方法应为帮助:

The StringEscapeUtils.unescapeJava method in the Apache Commons Lang API should be of help:

    String str = "\\u9601";
    str = StringEscapeUtils.unescapeJava(str);
    System.out.println(str);
