Arithmetic Exceptions and exception-handling statements

Expand Post »
hello everyone,
can anyone please help me to solve the following problem.

Write a program
1) To demonstrate division operation handling the arithmetic Exceptions.
2) To Access different elements of the given array:

int [] arr1 = {10,69,30,12,11,34,56,78,35}
Write exception-handling statements for ArrayIndexOutOfBounds Exception.


thank you,
regards,
shantuli

Re: Arithmetic Exceptions and exception-handling statements
There are two ways I know you can go about using exception handling to solve your question.

The first way is the use if simple if-statement:
Java Syntax (Toggle Plain Text)
  1.  for ( int i=0; i<max; ++i )
  2. {
  3. if (! (i < 0) || (i >= max) ) { cout << "Data: " arr1[1] << endl; 
  4. }
  5. }

The second method is actually using Exception handling:
Java Syntax (Toggle Plain Text)
  1. #include <iostream>
  2. using namespace std;
  3. #include <stdexcept>
  4.  
  5. int main()
  6. {
  7. int [] arr1 = {10,69,30,12,11,34,56,78,35};
  8.  
  9. for ( int i=0; i<max; ++i )
  10. {
  11. try{ cout << "Data: " arr1[1] << endl; 
  12. }
  13. catch (out_of_range &ex) { 
  14. cout << e.what() << endl; //the error message...
  15. }
  16. }
  17.  
  18. return 0;
  19. };

  19. };
Sounds like Home work.
I don't like to help people earn your degree. They should earn by their efforts.
So show efforts first

This is more funny!
Good work for submitting to a professor teaching you Java

Haha...if OP understands C++ that might actually help him.

In all seriousness though, think about the following:
1. When will division trigger an error (not necessarily just in Java)?
2. What does the ArrayIndexOutOfBoundsException actually refer to?

If you can answer the above, you can solve your problems.
