Week 2 Programming Assignment : Programming in JAVA 2023

 

What is Programming in Java?

Java is a popular object-oriented programming language that was first released in 1995. It is used for developing a wide range of applications, including desktop applications, mobile applications, web applications, and enterprise applications.

Here are some key features and concepts of Java programming:

Object-oriented programming: Java is an object-oriented language, which means that it focuses on the creation of objects that contain both data and methods that operate on that data.

Platform independence: Java programs can run on any platform that supports a Java Virtual Machine (JVM), which makes it a popular choice for cross-platform development.

Memory management: Java uses automatic memory management through a garbage collector, which helps to prevent memory leaks and makes it easier to write memory-safe code.

Exception handling: Java has a built-in mechanism for handling runtime errors or exceptions, which helps to ensure that programs can recover gracefully from unexpected errors.

Multi-threading: Java supports multi-threading, which allows programs to execute multiple threads of execution simultaneously, making it well-suited for developing concurrent applications.

Standard libraries: Java provides a large number of standard libraries that developers can use to build applications more quickly and easily, including libraries for networking, database access, and user interface development.

To get started with Java programming, you will need to install the Java Development Kit (JDK) on your computer. Once you have installed the JDK, you can use an Integrated Development Environment (IDE) like Eclipse or IntelliJ IDEA to write and debug your code.

To learn Java programming, you can start with the basics of the language, such as data types, control structures, and object-oriented programming concepts. There are many online resources and tutorials available for learning Java, including Oracle's official Java tutorials, which cover everything from the basics to advanced topics like concurrency and networking.

Complete the code segment to debug / complete the program which is intended to print 'NPTEL JAVA'.

Solution :

// Print as per requirement System.out.print(nptel+space+java+space+nptel);

CRITERIA TO GET A CERTIFICATE

Average assignment score = 25% of the average of the best 8 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 THE 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.
