Example
 

In this example we are going to see how we can catch the exceptionArrayIndexOutOfBoundException. ArrayIndexOutOfBoundException is thrown when we have to indicate that an array has been accessed with an illegal index. 
 

Suppose we have declared an array of int and the size of the array is 6, that means  that this array can store six values. Now suppose if want to access the seventh variable which does not exist, then it will throws the exception ArrayIndexOutOfBound. It means that there is no other value instead after that we are forcing the array to give the next value. 
The code of the program is given below:
try{
        int a[] =new int[6];
                for(int i = 0; i<7; i++){
               
                 a[i]=i;
                }      
        }catch(Exception e){
               System.out.println("Exception:"+e);
                }

output:
Exception:java.lang.ArrayIndexOutOfBoundException:6
