少了try catch?

int i;
URL url = new URL("http://www.cnn.com");
BufferedInputStream in = new BufferedInputStream(url.openConnection(
).getInputStream());
while( (i=in.read())!=-1 )
{
System.out.print((char)i);
}
A. Compile error
B. Runtime error
C. print the text got from the URL

【在 u****s 的大作中提到】

那就是c了
c的文字写的也不好，应该是print the html context which is from URL
print the text got from the URL , http://www.cnn.com也算是一种歧义了。
你如果贴题的话，搞点awt的或者swing的

int i;
URL url = new URL("http://www.cnn.com");
BufferedInputStream in = new BufferedInputStream(url.openConnection(
).getInputStream());
while( (i=in.read())!=-1 )
{
System.out.print((char)i);
}
A. Compile error
B. Runtime error
C. print the text got from the URL
