Programming (Java)

One radical vision of the early 1990s was to extend network computing capability to everyday life. In 1991, Sun Microsystems' engineers, led by James Gosling, believed this revolution would take shape through the union of computers and digital consumer devices. They gave life to the technology by creating a programming language called Java that would become the signature of this worldwide digital revolution. Today, Java is intricately interlaced within the Internet, mobile phones, handheld devices, games, navigation systems, e-business solutions, and just about every application and device that surround us in our day-to-day lives. Not only that, but Java is extremely useful and one of the first languages learned by new programmers. After learning the intricacies of Java and scripting itself, many other programming languages (such as the C-family, Python, Ruby, etc.) come much easier.

 
A course in Java programming will involve the following set of topics:

  • Primitive Data and Definite Loops
  • Parameters and Objects
  • Conditional Execution
  • Program Logic and Indefinite Loops
  • File Processing
  • Arrays
  • Classes
  • Inheritance and Interfaces
  • Array Lists
  • Java Collections Framework
  • Recursion
  • Searching and Sorting
  • Graphical User Interfaces
  • Implementing a Collection Class
  • Linked Lists
  • Binary Trees

public class helloWorld

{

            public static void main(String[] args)

            {

                        System.out.println(“Hello, World”);

            }

}

 

This may look confusing at first, especially since it’s only printing “Hello, World”, but once we discuss each line, Java programming becomes second-nature allowing you to write more complex codes like:

public int fib (int n)

{

            if (n <= 1)

            {

                        return  n;

            } else {

                        return fib(n-1) + fib(n-2);

            }

}

Although only about 5 lines of code, this method incorporates a few key ideas that you will learn in any introduction to Java class, such as: recursion, if-loops, and public methods.

There is a free online Java textbook made available from Hobart and William Smith Colleges that students should definitely take advantage of. Additional books on Java can be found on Amazon.com and Google. Finally, go to Oracle, the company that owns Sun Microsystems (creators of Java) for the best Java tutorials.

To fulfill our mission of educating students, our online tutoring centers are standing by 24/7, ready to assist students who need help with Java.
