Are you looking for the Answers to NPTEL Programming In Java Assignment 12? This article will help you with the answer to the National Programme on Technology Enhanced Learning (NPTEL) Course ” NPTEL Programming In Java Assignment 12 “
What is Programming In Java?
With the growth of Information and Communication Technology, there is a need to develop large and complex software. Further, those software should be platform independent, Internet enabled, easy to modify, secure, and robust. To meet this requirement object-oriented paradigm has been developed and based on this paradigm the Java programming language emerges as the best programming environment. Now, Java programming language is being used for mobile programming, Internet programming, and many other applications compatible to distributed systems. This course aims to cover the essential topics of Java programming so that the participants can improve their skills to cope with the current demand of IT industries and solve many problems in their own filed of studies.
CRITERIA TO GET A CERTIFICATE
Average assignment score = 25% of the average of best 12 assignments out of the total 12 assignments given in the course.
Exam score = 75% of the proctored certification exam score out of 100
Final score = Average assignment score + Exam score
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF THE AVERAGE ASSIGNMENT SCORE >=10/25 AND EXAM SCORE >= 30/75. If one of the 2 criteria is not met, you will not get the certificate even if the Final score >= 40/100.

Q2. A partial code fragment is given. The URL class object is created in try block.You should write appropriate method( ) to print the protocol name and host name from the given url string.
Code:-

try{
URL url=new URL("http://www.Nptel.com/java-tutorial");
//use appropriate method() to print the protocol name and host name from url
//Write the method() by replacing the blank space.
System.out.println("Protocol: "+url.getProtocol());
System.out.println("Host Name: "+url.getHost());
}
catch(Exception e){System.out.println(e);}
}
}
Q3. Write a program to create a record by taking inputs using Scanner class as first name as string ,last name as string ,roll number as integer ,subject1 mark as float,subject2 mark as float. Your program should print in the format
Code:-
//Read your first name
String f = s1.next();
//Read your last name
String l = s1.next();
//Read rollnumber
int n = s1.nextInt();
//Read 1st subject mark
double db = s1.nextDouble();
//Read 2nd subject mark
double db1 = s1.nextDouble();
double avg=(db+db1)/2;
System.out.println(f + l +" "+ n +" "+avg );
Q4. A program code is given to call the parent class static method and instance method in derive class without creating object of parent class. You should write the appropriate code so that the program print the contents of static method() and instance method () of parent class.
Code:-
public static void main(String[] args) {
// Call the instance method in the Parent class
Child c= new Child();
c.testInstanceMethod();
// Call the static method in the Parent class
Parent.testClassMethod();
}
}
Q5.Write a recursive function to print the sum of first n odd integer numbers. The recursive function should have the prototype
Code:-

//Call the method recursively.
return 2*n-1 + sum_odd_n(n-1);
