Remove the error by rearranging the following code

1. Remove the error by rearranging the following code.
public class ExceptionHandling
{
 public static void main(String[] args)
 {
 try
 {
 int arr[]={4,4,5};
 arr[6]=90;
 }

 catch(IndexOutOfBoundsException ex)
 {
 System.out.println("Index out of bound");
 }

 catch(ArrayIndexOutOfBoundsException ex)
 {
 System.out.println("Array Index out of bound"); }
 }
}
2. NDVI is calculated by using red band and Infrared band reflectance. It is used to identify
different kind of vegetation.
Image A (red band) = [ 3 15 54 16
54 23 21 75
0 3 51 0
23 0 43 98]
Image B (Infrared band) = [ 15 19 66 58
13 87 11 13
0 19 86 95
3 0 57 99]
NDVI Image C (of the same size, A) is generated by calculating NDVI for each pixel using the
formula =(Infrared-Red)/ (Infrared + Red)
Use a method to calculate NDVI and catch the exception.
3. Write a method to divide two user entered numbers, Use ‘throws’ to handle the exception.
Please make two different classes.(Class 1 should contain the method and Class 2 will
contain the main method from which it will be called)
4. Take user input in a fixed size of integer array (size =5). Use ‘throw’ to generate an exception
of data type and size. Use ‘finally’ block to display the array.
