68. User Define Exception or Custom Exception in JAVA

-

 //User Define Exception or Custom Exception

class ExceptionA extends Exception

{

ExceptionA(String msg)

{

super(msg);

System.out.println(msg);

}

}

class ExceptionB extends Exception

{

ExceptionB(String msg)

{

super(msg);

System.out.println(msg);

}

}

class user_define_exc

{

public static void main(String[] args) throws ExceptionA, ExceptionB

{

int n = Integer.parseInt(args[0]);


if (n % 2 == 1) {

throw new ExceptionA("Problem");

}

else

{

throw new ExceptionB("Big Problem");

}

}

}

OUTPUT:

--------------------------------------------------------------------

java user_define_exc 5

Problem

Exception in thread "main" ExceptionA: Problem

        at user_define_exc.main(user_define_exc.java:25)

---------------------------------------------------------------------

java user_define_exc 2
Big Problem
Exception in thread "main" ExceptionB: Big Problem
        at user_define_exc.main(user_define_exc.java:29)

Answer:   a. Identify the most likely reason why I could not enter the execute stage until the fourth cycle. One likely reason an instruction couldn't enter the execute stage until the fourth cycle is due to data hazards or resource conflicts: 1. Data Hazards: If the instruction depends on the result of a previous instruction that hasn't completed yet, it cannot proceed to the execute stage. This is often referred to as a Read After Write (RAW) hazard. 2. Resource Conflicts: If the required functional unit for execution (e.g., an ALU) is occupied by another instruction, the instruction will have to wait until the resource becomes available. b. Will "in-order issue/out-of-order completion" or "out-of-order issue/out-of-order completion" fix this? If so, which? Explain In-order issue/out-of-order completion  might help if the problem is related to instructions that can complete earlier being delayed by instructions that take longer to execute. This allows the...
