Topic outline

  • General

  • Basics

    This section provides a foundational constructs needed to learn Java language.  We will start with a simple program and then learn about variables and various operators.

    • Hello World!! Page

      Start with a very simple program.  The focus is to get you to write a very simple program, compile it and execute it.  You will jump in and do hands-on right from the beginning.

    • Java Variables Page
      Understand why do we need variables? Different data types and the rules to name them.  You will also learn about how to use the variables.
    • Arithmetic & Unary Operators Page

      How to performs arithmetic operations like addition and subtractions? How to use variables and literals in operations?  You will learn Arithmetic and Unary operators.

    • Relational & Conditional Operators Page
      How to compare values? This lesson discuss how to build logic by comparing various values. We then discuss on how do we compare the conditions.

  • Control Flow Statements

    How can we control the program flow? How can the program take different path depending the values?  We will look at if statements and loops. 

    • if & Switch statements Page

      You will learn about branching statements.  The program takes a particular path depend on the evaluation of the condition.  This will be beginning of the wonderful journey of building logic into your program.

    • Going round and round Page

      How to execute something repetitively? You will learn about various loop options and why there are so many different loops in Java.

    • Enhanced For Loop Page

      Enhanced for loop make it easier to look into individual elements from an array or a collection.

  • Arrays

    Arrays are used to store multiple values of same data type.  You will learn single dimension array and multi-dimensional array.

    • Arrays Page
      Why do you need arrays? How to create an Array and use it?
    • Two Dimensional Array Page

      How to store a table that has several columns?  The two dimensional array is used to store an table of values.

  • Object Oriented Programming

    You will learn about the concepts of the Object Oriented Programming and why it is needed.
