Try, Catch, Finally

[JiaPei Jen]

Once enter the try block, the code in the finally block will be executed with exceptions:
1. an exception arising in the finally block itself
2. the death of the thread
3. the use of System.exit()
4. Turning off the power to the CPU
Let me see if I get this right:
What if there is a finally block. The code enters the try block and an exception is thrown. However, there is no proper matching catch block?
Will the finally block executed? Will the method terminate after the finally block is executed?

hi jiapei,
it is perfectly legal to have a try and finally block without a catch block:
public class ex
{
public static void main(String[] str)
{
try
{
int i=5/0;
System.out.println("try block executed");
}
finally
{
System.out.println("finally block executed");
}
System.out.println("main is executed");
}
}
compiles perfectly but an Arithmetic Exception / by zero is thrown. The code in finally block will be executed and it prints: finally block executed
but the method(and program) will be terminated so none of the statements
System.out.println("main is executed");
System.out.println("try block executed");
will be executed though.

Thank you for your explanation with an example. It is very clear to me now.

sure jaipei,
this is quite obvious but just wanted to add that you cannot have any executable statements between try and finally.
