It's a test example below:

public class Test
{

public static void main(String[] args)
{
String s1="love",
s2="like";
System.out.println(s1==s2);
System.out.println(""+(s1==s2));
}
}

run java Test,the answer both are false except the second having a space aditonal.

Yes.
It's must follow the format below:
class implements class1,class2,...class n [extens classA](optional).

But you can't write like this below:
class extens classA,classB,classC.....
