CS506 Handouts, Assignments, Mid & Final Term Past Papers

CS506 Handouts, Assignments, Mid & Final Term Past Papers are given below. There are two modules in the course. The first module focuses on the fundamental ideas of Java as well as some more advanced subjects like Graphical user interface, Java Data base connectivity, Java Graphics, Socket programming, Serialization, and Multithreading. The second lesson focuses on creating web applications and covers Java Server Pages, Java Beans, Servlets, and JSF (Java Serve Faces). JDK 1.8, Tomcat server 9.0.0, and NetBeans IDE 8.2 are the tools used in this course for Java programming and web application development.

Java is quite resilient. Both against harmful programs like viruses and against inadvertent mistakes.
o As a result of all this checking, Java performs a little worse. (Or put another way, since C doesn’t check anything, it might be faster.) The JVM’s “verifier” examines the code upon loading to ensure that it has the correct Structure and does not utilize an uninitialized pointer or mix pointer and in types. This is a one-time “static” analysis that verifies the right structure of the code without actually running it. To ensure that some actions, such as pointer and array access, are only touching the proper memory.

The JVM additionally does “dynamic” verification during runtime. You’ll create code that crashes. As a result, Java is not susceptible to many typical flaws and security issues (such as “buffer overflow”). Since the runtime checker detects many common defects, the checks also make it simpler to locate them. Generally speaking, you will never write code that fails the verifier since your compiler is intelligent enough to produce only right code. As you debug, you will constantly write code that encounters runtime checks such as array out of bounds and null pointer

Java’s Runtime Security!CS506 Handouts

Additionally, Java provides a runtime security manager that may examine what activities a certain piece of code is permitted to perform. Because of this, Java allows untrusted code to operate in a “sandbox” where it can render to the screen but not access local data. A program written in C++ is referred to as source code. This source code is transformed into the machine code of the underlying system (such as Windows) by the C++ compiler. You must recompile the code using a Linux-based compiler if you want to run it on Linux.

You may need to adjust your code from time to time because of the variations in compilers.
Write Once, Run Anywhere (WORA) is a concept that Java has introduced. The source code of Java is what you use when writing a Java program. The Java compiler instead creates this source code for a software system called JVM (this compiled code is known as byte code), not for any underlying hardware system. We use many JVMs for

Lesson Learning Objectives:

After completing this course, you ought to be able to:

  • Explain some of the fundamental and advanced Java principles.
  • Create a Java graphical user interface.
  • Create or design a corporate web application.
  • Explain the various Java technologies.
  • Differentiate the various Java technologies.
  • understand how to use a particular technology in a particular situation

In Phase 4, the byte code validator checks the byte codes in an application before the java interpreter executes them. This guarantees the validity and compliance with Java security constraints of the byte codes for classes that are loaded via the internet (also known as downloaded classes). Due to the fact that java programs shouldn’t be able to harm your files and system (unlike computer viruses), java imposes strict security. Phase 5 is the last step, during which the computer interprets the program bytes at a time under the direction of its CPU. so carrying out the program’s instructions. The first time a program is run, it might not work.

The previous phases can each fail for a number of different reasons. The Java software would output an error message as a result. After making the necessary corrections, the programmer would go back to the edit phase and repeat the following phases to see if the changes were successful. The entire content of this handout was derived from Umair Javid’s book JAVA A Lab Course. This information may only be used by VU students enrolled in the Web Design and Development course; it may not be used for any other commercial purpose without the author’s permission.



The program starts on line 5, declared exactly for Java interpreter to run. The name of the parameter sent to main can vary. In C++, main() is global and outside classes. Java doesn’t have global variables or functions. Later, we’ll discuss main function declaration components.
