INDUSTRY SUPPORT :   All IT companies.

CRITERIA TO GET A CERTIFICATE

This course can have Associate in Nursing unproctored programming communication conjointly excluding the Proctored communication, please check announcement section for date and time. The programming communication can have a weightage of twenty fifth towards the ultimate score.

Final score = Assignment score + Unproctored programming exam score + Proctored Exam score
  • Assignment score = 25% of average of best 8 assignments out of the total 12 assignments given in the course.
  • ( All assignments in a particular week will be counted towards final scoring – quizzes and programming assignments).¬†
  • Unproctored programming exam score = 25% of the average scores obtained as part of Unproctored programming exam – out of 100
  • Proctored Exam score =50% of the proctored certification exam score out of 100
YOU WILL BE ELIGIBLE FOR A CERTIFICATE ONLY IF ASSIGNMENT SCORE >=10/25 AND
UNPROCTORED PROGRAMMING EXAM SCORE >=10/25 AND PROCTORED EXAM SCORE >= 20/50. 
If any one of the 3 criteria is not met, you will not be eligible for the certificate even if the Final score >= 40/100.

NPTEL Programming In Java Assignment 6 Answers 2022

Q1. Complete the code segment to print the following using the concept of extending the Thread class in Java:

—————–OUTPUT——————-

Thread is Running.

————————————————-

Solution Code : –¬†

public class Question61 extends Thread{
public void run(){
System.out.print(“Thread is Running.”);
}

public static void main(String args[]){

// Creating object of thread class
Question61 thread=new Question61();

// Start the thread
thread.start();
}
}

Q2. In the following program, a thread class Question62 is created using the Runnable interface Complete the main() to create a thread object of the class Question62 and run the thread. It should print the output as given below.

—————–OUTPUT——————-

Welcome to Java Week 6 New Question.

Main Thread has ended.

————————————————-

Solution Code :-

public class Question62 implements Runnable {

@Override
public void run() {
System.out.print(Thread.currentThread().getName()+” has ended.”);
}

// Create main() method and appropriate statements in it
public static void main(String args[]){
System.out.println(“Welcome to Java Week 6 New Question.”);
Question62 t=new Question62();
Thread tr = new Thread(t);
tr.setName(“Main Thread”);
tr.start();
}

}

Q3. ¬†A part of the Java program is given, which can be completed in many ways, for example¬†using the concept of thread, etc.¬† Follow the given code and complete the program so that your program prints the message “NPTEL Java week-6 new Assignment Q3“. Your program should utilize the given interface/ class.

Invalid HTML tag: tag name o:p is not allowed

Solution Code :-

// Interface A is defined with an abstract method run()
interface A {
public abstract void run();
}

// Class B is defined which implements A and an empty implementation of run()
class B implements A {
public void run() {}
}

// Create a class named MyThread and extend/implement the required class/interface

// Define a method in MyThread class to print the output
class MyThread extends B {
// run() is overriden and ‘NPTEL Java’ is printed.
public void run() {
System.out.print(“NPTEL Java week-6 new Assignment Q3”);
}
}

// Main class Question is defined
public class Question63 {
public static void main(String[] args) {
// An object of MyThread class is created
MyThread t = new MyThread();
// run() of class MyThread is called
t.run();
}
}

Q4. Execution of two or more threads occurs in a random order. The keyword ‘synchronized’ in Java is used to control the execution of thread in a strict sequence. In the following, the program is expected to print the output as given below. Do the necessary use of ‘synchronized’ keyword, so that, the program prints the Final sum as given below:¬†¬†
—————–OUTPUT——————-

Final sum:6000

————————————————-

Solution Code :-

/*
A simple class that demonstrates using the ‘synchronized’
keyword so that multiple threads may send it messages.
The class stores two ints, a and b; sum() returns
their sum, and inc() increments both numbers.
<p>
The sum() and incr() methods form a “critical section” —
they can compute the wrong thing if run by multiple threads
at the same time. The sum() and inc() methods are declared
“synchronized” — they respect the lock in the receiver object.
*/
class Pair {
private int a, b;
public Pair() {
a = 0;
b = 0;
}

// Returns the sum of a and b. (reader)
// Should always return an even number.
public int sum() {
return(a+b);
}

// Increments both a and b. (writer)
synchronized public void inc() {
a++;
b++;
}
}

/*
A simple worker subclass of Thread.
In its run(), sends 1000 inc() messages
to its Pair object.
(1000 may not be big enough to exhibit the bug on uniprocessor —
hardware more like 1000000 may be required).
*/
public class PairWorker extends Thread {
public final int COUNT = 1000;
private Pair pair;
// Ctor takes a pointer to the pair we use
public PairWorker(Pair pair) {
this.pair = pair;
}
// Send many inc() messages to our pair
public void run() {
for (int i=0; i<COUNT; i++) {
pair.inc();
}
}

/*
Test main — Create a Pair and 3 workers.
Start the 3 workers — they do their run() —
and wait for the workers to finish.
*/
public static void main(String args[]) {
Pair pair = new Pair();
PairWorker w1 = new PairWorker(pair);
PairWorker w2 = new PairWorker(pair);
PairWorker w3 = new PairWorker(pair);
w1.start();
w2.start();
w3.start();
// the 3 workers are running
// all sending messages to the same object
// we block until the workers complete
try {
w1.join();
w2.join();
w3.join();
}
catch (InterruptedException ignored) {}

System.out.println(“Final sum:” + pair.sum()); // should be 6000
/*
If sum()/inc() were not synchronized, the result would
be 6000 in some cases, and other times random values
like 5979 due to the writer/writer conflicts of multiple
threads trying to execute inc() on an object at the same time.
*/
}
}

Q5. Given a snippet of code, add necessary codes to print the following:

—————–OUTPUT——————-

Name of thread ‘t1’:Thread-0

Name of thread ‘t2’:Thread-1

New name of thread ‘t1’:Week 6 Assignment Q5

New name of thread ‘t2’:Week 6 Assignment Q5 New

————————————————-

Solution Code :-

public class Question65 extends Thread{
public void run(){

}
public static void main(String args[]){
Question65 t1=new Question65();
System.out.println(“Name of thread ‘t1’:”+ t1.getName());

Question65 t2=new Question65();
System.out.println(“Name of thread ‘t2’:”+ t2.getName());

// Write the necessary code below…
t1.setName(“Week 6 Assignment Q5”);
t2.setName(“Week 6 Assignment Q5 New”);
System.out.println(“New name of thread ‘t1’:”+ t1.getName());
System.out.println(“New name of thread ‘t2’:”+ t2.getName());

}
}
