Today , ARRAYS were discussed in the class. An Array is a group of contiguous or related data items that share a common name.  It enables us to develop concise and efficient programs. Arrays can be of any variable type. This lecture covered - Creating arrays, Declaration of arrays, Initialization of arrays , One Dimensional arrays, Multidimensional arrays , etc.


Examples:

1. Java code for finding the Largest & Smallest number in an Array

   import java.util.*;
    public class test1
    {
        public static void main(String [ ] args)
        {
            int i;
            int numbers []=new int[]{4,65,89,34,71,70,49,22,56,13};
            int smallest= numbers[0];
            int largest= numbers[0];
                    for(i=0;i<numbers.length;i++)
                    {
                        if(numbers[i]>largest)
                             largest = numbers[i];
                     
                          else if(numbers[i]<smallest)
                             smallest=numbers[i];
                           
                      }      
System.out.println("The largest number in this array is:" + largest);
 System.out.println("The smallest number in this array is:" + smallest);
        }
    }



  OUTPUT:
The largest number in this array is:89
The smallest number in this array is:4
