Answer 2

You have lots of mistake:

1 - where is try block, catch can't be without try block

2 - check proper opening and closing curly braces {}

3 - there is util package not utill

4 - there is List class not list class, class name should start from capital letter.

5 - where did you declare variable i

Answer 3

- remove catch block
catch (Exception e) {
System.out.println(e);
}
-instead catch, add throws after main() line , (it is simpler)
public static void main(String args[])
throws Exception {

-rename utill to util
-rename list to List
-declare i before while()
String i; //

public class URLConnectionclass
{
public static void main (String args[])
{
try
{
URL url = new URL("https://innovateindia.mygov.in/ppc-2022/");
URLConnection urlcon= url.openConnection();
Map<String, List<String>> header = urlcon.getHeaderFields();

for (Map.Entry<String, List<String>> mp: header.entrySet()){
System.out.println("\nComplete source code of the URL is---");
System.out.println("------------------------------------------");

BufferedReader br= new BufferedReader(new InputStreamReader(urlcon.getInputStream ()));

String i;
// print the source code line by line
while(( i = br.readLine()) != null)
{
System.out.println(i);
}
}
}
catch (Exception e)
{
System.out.println(e);
}
}
} //it's working...
