How are try/catch blocks implemented?

Question

If an exception occurs in a try block, how is execution transferred to the catch block? This is not a C#/Java/C++ question, I'm just wondering how it works internally.

Answer 1

this is not a c#/java/c++ question. How it works internally,how the line knows to go catch statement.

How this works internally makes this pretty much a c#/java/C++ question (because it will be implemented differently).

In Java, a try block installs itself into a special table (in the class file). When the JVM throws an exception, it looks at that table to see where the next catch or finally block to go to is.

Answer 2

When an exception occurs a special instruction is executed (usually called interrupt). This leads to executing a generic error handler that deduces which is the latest installed suitable exception handler. That handler is then executed.
