想表达如果相对地址以 \ 开头，like \data.html
if (addr.startsWith("\\")) // url like /data.html
{
String baseurl2 = baseurl.getHost();
URL relativeURL = new URL(baseurl2+addr);
}
else //url like data.htm, relative url
{
relativeURL = new URL(baseurl+addr);
}
when there is a relateive url named /data.html, it didn't go to if section,
but go to else section, made a result like
htt://www....//data.html
error in connecting.
What's wrong with the expression?SHould be sth wrong with "\\" here, how to
use escape

1. I never saw URL like \data.html
always use "/" instead of "\"
2. Look at URI.resolve, it does the right things.

【在 r*****r 的大作中提到】

: 想表达如果相对地址以 \ 开头，like \data.html
: if (addr.startsWith("\\")) // url like /data.html
: {
: String baseurl2 = baseurl.getHost();
: URL relativeURL = new URL(baseurl2+addr);
: }
: else //url like data.htm, relative url
: {
: relativeURL = new URL(baseurl+addr);
: }
