Chapter 12.4, Problem 12.4.8CP
Program Plan Intro
Exception handling:
In Java, the exception is an object used to signal the unexpected error occurred during a program execution.
- Exception is the error, which arises at run time and such errors can be handled in Java by exception handling.

1.class Nothing {public static void main(String args[]){int x = 0;int y = 20;int fraction = y/x;System.out.println("End Of Main");}}1. If there will occur exception, write the code that will handle the exception.
1.public class Test{
public static void main(String args[]){
Person p = null;
try{
}
p.talk();
} catch (NullPointerException e) {
System.out.print("There is a NullPointerException.");
}
catch(Exception e) {
System.out.print("There is an Exception.");
}
System.out.print("Everything went fine.");
}
what will be the result if you run this program?
O There is a NullPointerException. Everything went fine.
O There is a NullPointerException.
There is a NullPointerException. There is an Exception.
This code will not compile, because in Java there are no pointers.
Code completion and explain.
public class X { public static void main(String [] args) { try { badMethod(); System.out.print("A"); } catch (RuntimeException ex) /* Line 10 */ { System.out.print("B"); } catch (Exception ex1) { System.out.print("C"); } finally { System.out.print("D"); } System.out.print("E"); } public static void badMethod() { throw new RuntimeException(); } }.

- Look at the following program and tell what it will output when run:public class ExceptionTest{public static void main(String[] args){int number;String str;try{str = "xyz";number = Integer.parseInt(str);System.out.println("A");}catch(NumberFormatException e){System.out.println("B");}catch(IllegalArgumentException e){System.out.println("C");}System.out.println("D");}}arrow_forwardvoid foo () { try { throw new Exception1 (); print (" A "); throw new Exception2 (); print (" B "); } catch ( Exception1 e1 ) { print " handler1 "; } print (" C "); throw new Exception2 (); } void main () { try { try { foo (); print (" D "); } catch ( Exception1 e1 ) { print " handler2 "; } print (" E "); } catch ( Exception2 e2 ) { print " handler3 "; } } Write down the output of the program and justify why it is the output. Instead of the “replacement” semantics of exception handling used in modern languages, a very early design of exception handling introduced in the PL/I language uses a “binding” semantics. In particular, the design dynamically tracks a sequence of “catch” blocks that are currently active; a catch block is active whenever the corresponding try block is active. What will be the output of the following program if the language uses the “binding” semantics? Give the reasoning for your answer.arrow_forwardAnalyze the following code: public class Test{ public static void main(String[] args) { try { String s = "5.6"; Integer.parseInt(s); // Cause a NumberFormatException } } catch (Exception ex) { System.out.println("NumberFormatException"); int i = 0; int y = 2/i; } catch (RuntimeException ex) { } } System.out.println("RuntimeException"); The program displays NumberFormatException. The program displays RuntimeException. The program displays NumberFormatException followed by RuntimeException. The program has a compile error.arrow_forward
