exception_handle.java

// Write a program that takes as input the size of the array and the elements in the array. The program then asks the user to enter a particular index and prints the element at that index. Index  starts from zero. 

// This program may generate Array Index Out Of Bounds Exception  or NumberFormatException .  Use exception handling mechanisms to handle this exception. 

// Sample Input and Output 1:
// Enter the number of elements in the array
// 2
// Enter the elements in the array
// 50
// 80
// Enter the index of the array element you want to access
// 1
// The array element at index 1 = 80
// The array element successfully accessed


//  Sample Input and Output 2:
// Enter the number of elements in the array
// 2
// Enter the elements in the array
// 50
// 80
// Enter the index of the array element you want to access
// 9
// java.lang.ArrayIndexOutOfBoundsException


//  Sample Input and Output 3:
// Enter the number of elements in the array
// 2
// Enter the elements in the array
// 30
// j
// java.lang.NumberFormatException
