String literals are not allowed to span more than one line in Java.
在 Java 中，字符串文字不能跨越多于一行。
Here you are trying to create a string literal that spans more than one line:
在这里，您尝试创建一个跨越多行的字符串文字：
"<!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"
\"http://www.w3.org/TR/html4/loose.dtd\">\n"
Instead, split it up in multiple concatenated strings like this:
相反，将其拆分为多个串联字符串，如下所示：
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\"" +
"\"http://www.w3.org/TR/html4/loose.dtd\">\n"
Or place the entire string on one line like this:
或者像这样将整个字符串放在一行上：
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\" \"http://www.w3.org/TR/html4/loose.dtd\">\n"
The same issue occurs again at the <meta>tag.
同样的问题再次出现在<meta>标签上。
