for(int i=0;i<hello.length;i++) {
    String s=hello[i].toLowerCase().trim();

推荐答案

因为双引号分隔字符串值，当然你必须将它们转义为代码文字双引号，但是你可以做它没有这样逃避：

Because double quotes delimit String values, naturally you must escape them to code a literal double quote, however you can do it without escaping like this:

System.out.println('"' + s + '"');

这里，双引号字符（ ）已被编码为 char 值。我发现这种风格比笨拙的反斜杠方法更容易阅读更清晰。但是，这种方法只能在正在追加单个字符常量，因为'char'（当然）只是一个字符。

Here, the double quote characters (") have been coded as char values. I find this style easier and cleaner to read than the "clumsy" backslashing approach. However, this approach may only be used when a single character constant is being appended, because a 'char' is (of course) exactly one character.
