JAVA正则表达式双引号问题

private String[] mid = {"whilenow","people","humans"};
上面的字符串如何用正则表达式转换为private String[] mid = {<span class="character">“whilenow”</span>,<span class="character">"people"</span>,<span class="character">"humans"</span>};
如果引号的数量不止3个呢，可以不用正则表达式
只是要求把双引号及其里面的内容转换为<span class="character">“引号内容”</span>

Answer 1

能不能不用正则表达式。。。你可以写个方法把<span class="character">和</span>抽离出来撒，然后把这个数组private String[] mid = {"whilenow","people","humans"};里面的元素按参数传递进去。。。字符串拼接的方式放回字符串数组啊

Answer 2

        String[] mid = {"whilenow", "people", "humans"};
        System.out.println(Arrays.toString(mid));
        for(int i = 0; i < mid.length; ++i) {
            mid[i] = String.format("<span class=\"character\">\"%s\"</span>",mid[i]);
        }
        System.out.println(Arrays.toString(mid));

[whilenow, people, humans]
[<span class="character">"whilenow"</span>, <span class="character">"people"</span>, <span class="character">"humans"</span>]

Answer 3

String s ="private String[] mid = {\"whilenow\",\"people\",\"humans\"};";
System.out.println(s.replaceAll("\"\\w+\"", "<span class=\"character\">$0</span>"));

这样可以
