Why should I worry about detected exceptions in Java?
Exceptions help you when something in your code or logic breaks. Instead of using if and else to handle errors that contain more code for writing, and the code itself may break in the process, you can use exceptions. Exceptions allow you to write code, as you usually do, and process them by adding try , catch and finally blocks. The program will then use exceptions to indicate that an error has occurred.
try is a block of code in which an exception can occur, and it must contain at least one catch (or many) or, finally, a block.catch is a block of code that will handle a specific type of exception.finally is a block of code that is guaranteed to execute after a try block.
"To throw an exception, use the throw statement and provide it with an exception object - a Throwable descendant - to provide information about the specific error that occurred. The method that throws the thrown exception is thrown should include a throws clause in its statement." - From Oracle Exception documentation
Exception objects contain more information about the error that it causes. "When a chain is excluded, an exception may indicate an exception that it caused, which in turn may indicate an exception that it caused, etc." - From Oracle Exception documentation
I have noticed several times that the inclusion of exception checkpoints in Eclipse and Android Studio has the "Caught Exceptions" checkbox selected by default. Is there a reason why I should leave this box unchecked?
The catch exceptions check box is used if you want execution to be paused when an exception is thrown and catch it using the
catch clause.
Android
Android exceptions are almost the same as java. However, Android does not have a console, so you should report exceptions to the user. The way exceptions are displayed to the user is in a toast or dialog.
