try {

} catch (Exception e) {

}

All a java try catch statement does is runs certain code if an exception happens inside of try{}. Try catches are very important and you'll probably use them a lot as a software developer!

This try catch java code can be tricky at first... But SURELY you'll get it :) If you followed along, congrats! You learned-by-doing!

I hope you enjoyed this try catch java tutorial! I like to have a nice mix of tutorials and actual projects for you all :)

Exceptions in java just mean something in your code got messed up, then it shows a message where you find the problem. ✅Hopefully, what I've taught you will help you see exceptions in java in a different light.

Java exceptions look scary, but they're actually a friendly message that gives you loads of information for how to fix your code. The name of the exception will give you a hint as to what went wrong, it provides an exact trace of which code was hit and the exception even gives you the exact line number where it occurred.

This java exceptions code can be tricky at first... But SURELY you'll get it :) If you followed along, congrats! You learned-by-doing!

Why learn Java?

Java is a general-purpose, class-based, object-oriented computer programming language that was designed by James Gosling at Sun Microsystems in 1995.

Key Highlights of Java:

Platform Independent: This allows programmers to develop applications that can run on any operating system.

Usability of Java: Java is most widely used programming language. It is present everywhere. It really doesn't matter which domain you are working in, you will surely come across Java sooner or later!

Open Source: The good news is that Java is available for free! All the development tools and the environment (JRE & JDK) that is used to develop Java applications are absolutely free of cost.

Android: Irrespective of the fact that you are tech savvy or not, most of us are badly bitten by the Android bug! Android is in great demand today and fortunately you need Java for Android development. Hence, the importance of Java has increased even more.

Hadoop: Hadoop is one of the most trending frameworks for processing Big Data. It has been designed and developed in Java.

Learn Programming in Java - Lesson 16: Exceptions

In this video we will walk you through the basics of Java exceptions and how you use them to handle errors in your program code. We'll talk about the different types of errors you can encounter in your program and over how you can catch those errors using exceptions. The goal is not cover this topic in depth, but introduce enough of the key concepts so that we can build upon what we've learned in later lessons.

Java Clean Code Tutorial #7 - Exception Handling - Throw Exceptions Instead of returning Error Lists

Validation is present in virtually all java applications. I feel that using an error flag / error list should be avoided and replaced with an exception being thrown up the stack when an illegal validation is identified.

When you use error flags or error lists, you introduce the scope to introduce bugs regarding the current return status of the validation. This can also clutter your code with validation logic outside the ‘validate’ object.

If you use a validation object with an error list, try to avoid using a list as an output argument. I.e. The method will change the state of an list parameter passed in. Rather return a Immutable List/Set of validation errors.

When you throw exceptions this is not possible as it will be propagated up the stack and dealt with in your try/catch block.

Software is written once and read hundreds of times. So let’s make our fellow developers life easier.

Why clean code?
Simple. Clean code allows us to confidently make changes and deliver more features quickly to our customers.

Java Finally Keyword - Finally Java Tutorial

Free preview of my Java course:

The finally keyword in java goes after a try catch block. When you get nasty errors, java tries to help you with an Exception. An exception tries to tell you what went wrong. So we try code in the try curly braces, then if an Exception happens, we run code in the catch curly braces, and at the end, we always run code in the finally curly braces.

try {

}
catch(Exception e) {

}
finally{

}

I hope this helps you with the java finally keyword :) At first, I had no idea what the finally java keyword was...

I hope you enjoyed java finally keyword tutorial! -
