Course Outline

Factorial

Factorial in Mathematics is a mechanism in which the product of all the whole numbers less than and equal to the given number is calculated. For example: 3! = 6

Fibonacci Series

Fibonacci Series is the series of numbers obtained by adding the previous two numbers. For example: 1 1 2 3 5 8 13 

Palindrome

A palindrome is a sequence of numbers or characters similar to its reverse. The number/character is similar when read from the front and the end. For example: 12321, 34543 

Reversal of a String

A string is a set of characters. Reversal of a String is a program where each character of a string is reversed. For example: string = hello, reversed string = olleh

Prime Number

The number is divisible by 1, which is called the prime number. A prime number is a program to find if the given number is prime or not.

Armstrong Number

The Armstrong number is a number that is equal to the sum of cubes of its digits. Armstrong number program checks if the given number is an Armstrong number or not. For example: 153

Pattern Programming

Pattern programming is the sequence of numbers/characters/symbols in any defined pattern. Pattern programming is writing codes for creating such patterns. For example: pyramid pattern, inverse pyramid pattern, etc.

Matrix multiplication

Matrix multiplication is the product of two matrices, and a matrix is a two-dimensional representation of numbers that consists of rows and columns.

Call by Value

The call by value is a method of passing arguments to a function that copies the actual value of an argument into the function's formal parameter. 

Sorting of an Array

In this module, we will write a program to arrange the elements of an array into ascending order. Different sorting algorithms can be used to sort.

Frequently Asked Questions

Is Java different from C++?

Yes, they are different. 

Both Java and C++ have been heavily used for the last 4-5 decades. They both follow the same syntax. Both are based on the object-oriented concept and are used in major enterprise platforms of the world. Hence converting a program from Java to C++ and vice versa is easy as the style and syntax of both are very similar.

However, despite these similarities, the two languages are very different. Java is an interpreted language, while C++ is a compiled language. Memory management (garbage collection) is automatic in Java, whereas in C++, memory has to be managed manually. Java is memory safe, i.e., any assignment of values outside of the given array parameters will result in an error, whereas C++ is not hardbound on this. Java being more of an interpreted language, is slower than C++. C++ code gets compiled to binaries and is faster to run than Java programs. Java has had multithreading support since its inception, whereas C++ has proper multithreaded support added in the C++11 revision. Java has no pointers, whereas C++ has. C++ has both global and local namespaces, whereas Java has no concept of the namespace. Java code is portable, whereas C++ code has to be compiled on each platform before running.

Is Java Code Portable?

Yes, Java programs are portable across hardware platforms and operating systems. It is portable because of many reasons. The Java language is completely specified, with all data-type sizes and formats being included in the language definitions.

 

Secondly, the Java class library is available on any machine with a Java runtime system making it possible to use the same class library on every platform. Thirdly, Java works as byte code. The JRT or Java runtime system does not compile your source code directly into machine language, an inflexible and no portable representation of your program. Instead, Java programs are translated into machine-independent byte code. The byte code is easily interpreted and can be executed on any platform having a Java runtime system.

What makes Java Secure?

The Java language is very secure because it is inherently difficult to write incorrect code or viruses that can corrupt or steal your data or harm hardware such as hard disks. There are two directions that make Java programs secure. We have no pointer arithmetic, garbage collection, array bounds checking, and no illegal data conversions at the interpreter level. And at the browser and applet level, we have no local file I/O, sockets bound to the host only, and denial of calls to native methods.

Is Java Robust?

Yes, Java is very robust due to many reasons such as no pointer arithmetic, automatic garbage collection resulting in no bad addresses, array and string bounds checking, no jumping to bad method addresses, and well-defined interfaces and exceptions.

Why should I learn Java ?

Java is one of the most popular high-level programming languages in present times. We can design customized lightweight multipurpose applications in Java. It is a must to get any kind of programming job in the backend or application engineering team in any software industry. One should learn Java because of the following reasons

  1. Java has been the number one choice of programmers for over a decade 

  2. Java expertise and experience fetch more salary

  3. Java has an easy learning curve

  4. Java has a large community base, up to date documentation, and abundant API set to choose from

  5. Java is free to use and has huge offerings in open source. 

  6. Java is platform-independent

  7. Java is multipurpose

What are the basic Java programs ?

Every programmer starts his or her Java journey with a simple Hello World program. This also serves as a status check that the JAVA setup is correct. After that, the learner should move towards basic programs that are focused on Java fundamentals, such as arrays, functions, loops, and classes. Some of the basic programs to begin with are:

 

  1. Finding factorial of a number

  2. Building a dynamic list of integers and doing a binary search in it

  3. Writing a simple Calculator tool doing basic BODMAS operation

  4. Checking if a string is Palindrome or not

  5. Given a number n, generate all Fibonacci numbers up to not   

  6. Sorting a list of integers using your own version of Quicksort (not library function)

  7. Detecting a sub-string within a given string

  8. Check if a number is PERFECT.

  9. Generating all prime numbers less than a given number

Where can I practice Java programming?

You can practice Java programming using two ways. First, you can install Java, and any of its recommended IDEs on your local machine set the required path, and start writing programs. Secondly, there are many websites that help programmers to practice Java coding online. The coding skill of a programmer who is learning a programming language can be improved at a much faster rate if he or she solves more and more coding challenges and these websites offer challenging problems in abundance.

Java Basic Programs

Java is a popular programming language that is widely used for developing web applications, mobile apps, and desktop applications. It is a versatile language that can handle complex programming tasks with ease. In this article, we will discuss some of the basic programs in Java.

Factorial Program

The factorial program is one of the fundamental programs in Java. It calculates the factorial of a given number. The factorial of a number is the product of all the numbers from 1 to that number. For example, the factorial of 5 is 54321, which is equal to 120.

Fibonacci Series Program

The Fibonacci series program is another important program in Java. The Fibonacci series is a sequence of numbers in which each number is the sum of the two preceding numbers. The first two numbers in the series are 0 and 1. The next number is the sum of the two preceding numbers. For example, the first 10 numbers in the Fibonacci series are 0, 1, 1, 2, 3, 5, 8, 13, 21, and 34.

Palindrome Program

The Palindrome program is used to check whether a given word or phrase is a palindrome or not. A palindrome is a word or phrase that is spelled the same way forwards and backward. For example, the words "racecar" and "level" are palindromes.

Reversal of a String Program

The Reversal of a String program is used to reverse a given string. This program is used to reverse a word, phrase, or sentence. For example, if the input is "Hello World", the output will be "dlroW olleH".

Prime Number Program

The Prime Number program is used to check whether a given number is a prime number or not. A prime number is a number that is divisible only by 1 and itself. For example, 2, 3, 5, 7, 11, and 13 are prime numbers.

Armstrong Number Program

The Armstrong Number program is used to check whether a given number is an Armstrong number or not. An Armstrong number is a number in which the sum of the cubes of its digits is equal to the number itself. For example, 153 is an Armstrong number because 1^3 + 5^3 + 3^3 = 153.
