Speaker 1 (13- Summary)
Let's quickly recap what you learned in this section.
0:05
S…
Speaker 1 (13- Summary)
We have three types of exceptions in Java.
0:08
S…
Speaker 1 (13- Summary)
We have checked exceptions that get checked at compile time.
0:11
S…
Speaker 1 (13- Summary)
These are the exceptions that we should anticipate and explicitly handle.
0:15
S…
Speaker 1 (13- Summary)
We also have runtime exceptions that occur as a result of programming
0:19
S…
Speaker 1 (13- Summary)
errors, and we have errors that represent external errors.
0:23
S…
Speaker 1 (13- Summary)
To handle exceptions,
0:24
S…
Speaker 1 (13- Summary)
we wrap our code inside a try -catch block.
0:26
S…
Speaker 1 (13- Summary)
We can have multiple catch blocks to catch different types of exceptions.
0:31
S…
Speaker 1 (13- Summary)
To throw an exception,
0:32
S…
Speaker 1 (13- Summary)
we use the throw keyword.
0:33
S…
Speaker 1 (13- Summary)
We can create custom exceptions by subclassing the exception or
0:37
S…
Speaker 1 (13- Summary)
the runtime exception class.
0:38
S…
Speaker 2 (13- Summary)
And finally,
0:39
S…
Speaker 1 (13- Summary)
we can wrap an exception inside a more general exception.
0:42
S…
Speaker 1 (13- Summary)
This technique is called chain -in exceptions and is used in building libraries
0:47
S…
Speaker 1 (13- Summary)
and frameworks.
0:48
S…
Speaker 1 (13- Summary)
So that brings us to the end of this section.
0:50
S…
Speaker 1 (13- Summary)
In the next section,
0:51
S…
Speaker 1 (13- Summary)
we're going to talk about generics.
0:52
S…
Speaker 1 (13- Summary)
So I will see you in the next section.
