How to handle exception in static block

In this video, I have explained how handling exception in static block differs from conventional methods. 1. Why we have to mandatorily use try catch block inside static blocks? 2. Can I throw a runtime exception inside try catch block? 3. How can I stop the execution where there is a exception in try catch inside static block? 4. System.exit() method usage 5. Can we consider about removing the static block itself?
