JAVA Interview Questions

The finally clause is used to provide the capability to execute code no matter whether or not an exception is thrown or caught. If an exception occurs and there is a return statement in catch block, the finally block is still executed. The finally block will not be executed when the System.exit(0) statement is executed earlier or on system shut down earlier or the memory is used up earlier before the thread goes to finally block.

try{
//some statements
}
catch{
//statements when exception is caught
}
finally{
//statements executed whether exception occurs or not
}

Does the order of placing catch statements matter in the catch block?

Yes, it does. The FileNoFoundException is inherited from the IOException. So FileNoFoundException is caught before IOException. Exception’s subclasses have to be caught first before the General Exception
