reader/writer support only cahracter and input/output
stream support only bytes input stram and the java reader
class has only one differnce and that is input stream only
support bytes and the reader class only supports the
character.
These are IO streams but difference their
InputStream/OutputStreams class are byte-oriented
streams.this streams read and write in byte oriented.
InputStream/OutputStreams are never support unicode characters.
Reaer/writer class are belongs to the charecter stream
this streams read and write in character oriented Streams .
Reaer/writer are never supports unicode characters.
The Reader/Writer class hierarchy is character-oriented, and
the Input Stream/Output Stream class hierarchy is byte-oriented.
Basically there are two types of streams.Byte streams that
are used to handle stream of bytes and character streams for
handling streams of characters.In byte streams input/output
streams are the abstract classes at the top of
hierarchy,while writer/reader are abstract classes at the
top of character streams hierarchy.
My application URL :
http://localhost:8080/Application/Login.jsp. When a user
enter this url in IE then, how it get Login.JSP Page
exactly? what are the processes will happen from when we
submit the URL to get Login.jsp?
interface X{
void m1();
void m2();
}
class Child2 extends Object implements X {
public void m1(){
System.out.println("Child2 M1");
}
public void m2(){
System.out.println("Child2 M2");
}
}
public class ParentChildInfterfaceDemo {
public static void main(String[] args){
X x = new Child2();
X x1 = new Child2();
x.m1();
x.m2();
x.equals(x1);
}
}
Will the above code work?
If yes? Can you please explain why the code
x.equals(x1) will work as the equals method is called on
interface reference vaiable?
Consider that class classA, abstract class classB, and
final classC have been defined.Which one of the following
is correct?
1. classA extends classC implements classB
2. class A extends classB, classC
3. classA extends classB
4. classB implements classC
