try {// Normal execution path. throw new EmptyStackException ();} catch (ExampleException ee) {// Deal with the ExampleException.} finally {// Always run when leaving the try block (including finally clauses), regardless of whether any exceptions were thrown or whether they were handled.
The Go developers believe that the try-catch-finally idiom obfuscates control flow, [59] and introduced the exception-like panic / recover mechanism. [ 60 ] recover () differs from catch in that it can only be called from within a defer code block in a function, so the handler can only do clean-up and change the function's return values, and ...
In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program.
Scala runs on the Java platform (Java virtual machine) and is compatible with existing Java programs. [15] As Android applications are typically written in Java and translated from Java bytecode into Dalvik bytecode (which may be further translated to native machine code during installation) when packaged, Scala's Java compatibility makes it well-suited to Android development, the more so when ...
In Object Pascal, D, Java, C#, and Python a finally clause can be added to the try construct. No matter how control leaves the try the code inside the finally clause is guaranteed to execute. This is useful when writing code that must relinquish an expensive resource (such as an opened file or a database connection) when finished processing:
The finally block is always executed, even if the try block contains control-passing statements like throw or return. In Java, this may result in unexpected behavior, if the try block is left by a return statement with some value, and then the finally block that is executed afterward is also left by a return statement with a different value.

Resources must implement java.lang.AutoCloseable. try-with-resources statements are not required to have a catch or finally block unlike normal try-catch-finally ...
