This course will cover Java SE 7 fundamentals and equip the students to find the OCA Java SE 7 Programmer certification (IZ0-803) easy to pass. This certification is hard to achieve without proper guide and teaching. I have organised this course from top to bottom approach which will start with variables and end with abstracts, interfaces and exceptions handling in java. By the end of this course, students will not just follow any java App course but would fully understand and easy to follow without looking on google for every single error. Remember, looking for errors to resolve takes hours of your valuable time.
This course is designed to point out key points in order to make it easy for students to pass the exam. OCA certificate is an achievement that should proud of and Employers respect the certification and you will be better equipped in the interview.
The course is organized in a way that you would easily follow without any extra animation to divert your attention from the course materials.
I have put a lot of questions during the lessons and made it clear why a particular question is right or wrong. Those questions are not easy but tricky and misleading and these are exactly the questions which makes you ready for exam.
I would strongly recommend that even if you are an experienced java programmer and would like to to pass the exam IZ0-803 then you have to follow each lesson step by step and would notice that a lot of question will be confusing without proper guide-lines and instructions.
Java Development Kit the key to compile and run any java program. It easy and straight forward to install, go to oracle website and download the appropriate version for your operating system.
In this lesson you would learn how to set path to java compiler. Operating system would know where to find javac and java application to compile and run the java program. This is also to refresher your memory that how to compile and run a java program.
Identifiers in java is key to know as this will allow a programmer to decide what is an appropriate name for a variable, class name, method name and block name.
Reserved or keyword words in java are not being used as identifiers as this will create compile time error, therefore, it a must that you should reserved keywords for exam and real life. This is why i said in the beginning that following just a java course where it shows you straight away to create an App would not make you a good programmer unless you know the language rules properly.
Primitives are not objects but they are the fundamental data types of java language. Primitives are key to know as you will be building upon and know why we need objects to work with.
In this lesson you would learn integral Data types like byte, short, int, and long, these are part of primitive data types.
Floating point data types in java language are used for decimal points and they are part of primitive data types.
Non-Numeric data types are char, boolean and String. char and boolean are part of primitive data types but String is as object used for text.
Literals are simply the data of primitive data types. In this lesson I will go through the value of byte, short, int and long and you would know that what values are allowed to assign to integral data types.
In this lesson you would learn floating point valid values and as you know floating point is part of primitive data type which are float and double.
Non-Numeric literals will be thought in this lesson. Java is Unicode based and you would learn different form of non-numeric literals. Non-numeric primitive data types are char and boolean.
In this lesson you would learn that how to assign values and result of an expressions to primitives.
Casting is key to know otherwise you will not be happy in the Exam. Primitive casting are divided in to two ways. Widening and Narrowing. Widening is from byte to short to int to long to float and to double. But Narrowing is from double to float to long to int to short and to byte. Widening is done by the compiler implicitly but Narrowing should be done by the programmer explicitly.
You should know java main() method as a program that what does each modifier mean and what are they for? In this lesson you will know public static void modifiers in main() and their orders.
Variable types are key to know and you should know that how long a variable will live or in another word when will you be able to use variable in class, method and in blocks.
