Catch exceptions for array index out of bounds or dividing

// Catch exceptions for array index out of bounds
// or dividing by 0
import javax.swing.*;

{
String inStr;
int num, result;
int[] array = {12, 4, 6, 8};

try

{
result = array[x] / num;
JOptionPane.showMessageDialog(null, \"Result of division is \" + result);

JOptionPane.showMessageDialog(null, \"Result accessing array is \" + result);
}
}
catch(ArithmeticException error)
{
JOptionPane.showMessageDialog(null, \"Arithmetic error - division by 0\");   
}
catch(IndexException error)

Solution

Hi,

Addded ArrayIndexOutOfBounds catch bloack and highlighted the code changes below.

DebugTwelve3.java

import javax.swing.*;
public class DebugTwelve3
{
public static void main(String[] args)
{
String inStr;
int num, result;
int[] array = {12, 4, 6, 8};
inStr = JOptionPane.showInputDialog(null, \"Enter a number \");
num = Integer.parseInt(inStr);
try
{
for(int x = 0; x < array.length; ++x)
{
result = array[x] / num;
JOptionPane.showMessageDialog(null, \"Result of division is \" + result);
result = array[num];
JOptionPane.showMessageDialog(null, \"Result accessing array is \" + result);
}
}
catch(ArithmeticException error)
{
JOptionPane.showMessageDialog(null, \"Arithmetic error - division by 0\");   
}
catch(ArrayIndexOutOfBoundsException error)
{
JOptionPane.showMessageDialog(null, \"Index error - subscript out of range\");
}
}
}
