- Handling exceptions are one of the crucial tasks for any programmer. Exception handling in Java is an easy task once we learn and understand the concepts.
What we will learn in this Video?
1. What are the Exception and Error
2.Checked and unchecked exceptions
3. Try Catch block
4. Finally block in Java

NOTE: This video tutorial about Exception handling is just a getting started guide and not an entire course. I recommend reading further if you are interested.

At 29.45, In point 1, Hope catch is not a mandatory to execute finally block. We can just have try and finally.
public static void main(String[] args) {
try {
int a = 5;
System.out.println(a);
}
finally {
System.out.println("I can execute without catch");
}
}
Yes catch is not mandatory as long as u r using finally.
Excellent ❤
Good explanation

Hi sir. I'm unable to create custom exception using "throw new". It says "cannot be resolved to type". Please suggest anything sir.
Hello bro, I have a question.... e.printstacktrace should be applied only for the generic exception?? Or can it be used for null pointer or arithmetic exceptions as well??
It will just print the exception no matter the type of the exception

Hi bro.. one doubt.. can we have 4 - 5 catch in a method or in a loop ?? Is it a good practice..
U can write as many catch blocks as u need if that's your requirement or if u suspect ur function will throw these many types of exception u can catch them multiple times. No issues
@@LearnAutomationOnline
Thanks for the reply bro.
Below for loop is iteration for json response which has multiple list inside it and I have made if conditions for fields for checking null .In some iteration it gives index out of bound exception , hence giving try catch for individual if loops.
If I give overall, one try catch block for whole code, it is not executing properly ..
could you plz advise below is good practice?
For ()
{
Try{
If ()
}
Catch

Hi sir, 🙋 i need the ppt, can u pls send me?
can ive the notes u used in this java crash course videos to refer bro, pls
I will discard most of the ppts once I make the videos. Sorry
@@LearnAutomationOnline ok bro I took notes,👍
i need this ppt bro pls
I need PPT sir
Why final keyword is missing in this crash course?
@Learn Automation Online Pls share me the Full java PPT.
Why? Prepare it by yourself while learning that's the best way to learn and remember
I want this PPT
31 .00 minutes la doubt sir return statement classmate.method name yen podanum athu konjam detaila solunga sir
Please help bro athu mattum purila sysoutla classname.method potrukinga epdi call achi solunga plsssss
Try- catch block main method only it comes?
You can write it any function. Not only for main method. Infact all the codes should be surrounded by try catch that's the best practice.
I couldn't find string buffer and string builder in this playlist for java crash course ji.
Sorry I didn't add it seems. Kindly check now and please let me know.
@@LearnAutomationOnline I see it now. Good to go☺
Print stack trace na ena bro
Bro, try block la exception ku aduthu iruka line run aaganum na ena pananum,, exception vantha odaney control catch block ku poiduthu, other try block la iruka codes work aaga matrnguthu epdi bro pandranthu,..???
That's how try catch works right, the moment an exception is occurred, corresponding catch block will continue the execution.
@@LearnAutomationOnline correct arul, but, let consider one example
try {
Sys("first line)
Sys(100/0)
Sys("third line")
}
Catch {
Sys(exception) }
The exception occurred in the second line, so after the second line the catch block will execute,,,, and my doubt is, how to execute the the third line, i want to execute the third line, so how can i do that? Could you please clarify this one.
Throw throws different sollala bro
