suppose we have an interface & that interface contains five
methods. if a class implements that interface then we have
to bound that to give tha definition of all five methods in
that class. If we declare that class as abstract then can
we call only two methods to give the deinition of that
method & i don't want to give the definition of all the
methods? can it possible

Answer / nitin
yes it is possible, just make rest of the method abstract
explictly.
Example:
public interface Human {
public void canEat();
public void canThink();
public void canTalk();
public void canImegine();
public void canLove();
}
public abstract class Man implements Human {
public abstract void canEat();
public abstract void canImegine();
@Override
public abstract void canLove();
@Override
public void canTalk() {
}
@Override
public void canThink() {
}
}
public class Nitin extends Man{
/**
* @param args
*/
public static void main(String[] args) {
}
@Override
public void canEat() {
}
@Override
public void canImegine() {
}
@Override
public void canLove() {
}
}

Answer / suresh chand
yes,it is possible that abstract class implements zero,
one,two,three or four interface methods but not all i.e
five. After this concrete class which extends the abstract
class, implements the remaining methods.

Answer / sai hegde
It's possible that your abstract class implements one/all or
none of the interface methods. The concrete class that
extends your abstract class will have to provide
implementations for the methods that have not been
implemented in your abstract class.

i think we can accomplish by using adapter design pattern.

public interface InterfaceSample {
public void method1();

public void method3();

}
abstract class Abstclass implements InterfaceSample{
public abstract void method1();
public abstract void method2();
public void method3(){
System.out.println(" astract method3 ..............");

public class Sample extends Abstclass {
public void method1(){
System.out.println("method1 ..............");

System.out.println("method2 ..............");
}
public void method4(){
System.out.println("method4 ..............");

Sample s1 = new Sample();
s1.method1();
s1.method2();
s1.method3();
s1.method4();
}
}

The following program reads data (details of students) from a file named students.txt and converts it into e-mail addresses. The results are written to a file named studentemail.txt. students.txt consists of a number of lines, each containing the data of a student in colon delimited format: Last Name:First Name:Student Number Each input record is converted to an e-mail address and written to studentemail.txt in the following format: the first character of the last name + the first character of the first name + the last four digits of the student number + “@myunisa.ac.za” import java.io.*; public class EmailConverter { public static void main(String[] args) throws IOException { BufferedReader input = new BufferedReader(new FileReader ("students.txt")); PrintWriter output = new PrintWriter(new FileWriter ("studentemail.txt")); String line = input.readLine(); while (line != null) { // Extract the information for each student String[] items = line.split(":"); // Generate the email address String email = "" + items[0].charAt(0) + items[1].charAt(0) + items[2].substring(4,8) + "@myunisa.ac.za"; email = email.toLowerCase(); // Output output.println(email); line = input.readLine(); } input.close(); output.close(); } } Rewrite the class so that it handles possible errors that may occur. In particular, it should do the following: • It should catch at least three appropriate exceptions that might occur, and display suitable messages. • At this stage, the program will not run correctly if there is an empty line in the input file. Change the program so that if an empty line is encountered, an exception is thrown and the empty line is ignored. This exception should be handled with the display of a suitable error message. • Before the e-mail address is added to the output file, check if the student number has 8 digits. If not, throw an InvalidFormatException (which the program should not handle itself)
