I have created a Java program.I have defined array length to be 10 but when I am giving input 3,5,18,1,3,7,16,14,15,11,13,19 which contains more than 10 values the program is running fine. I am new to Java. Please help me understand how it is happening. My code is :

  package ds;



  import java.util.Scanner;



  public class Trade {



public static void maxprofit(Stringprice)

{

    int prices= new int[price.length];

    for(int i=0;i<price.length;i++)

    {

        prices[i]=Integer.parseInt(price[i]);

    }

    int min=prices[0];

    int max=prices[prices.length-1];



    for(int i=0;i<prices.length;i++)

    {

        if(i<prices.length-1-i)

        {

            if(prices[i]<min)

            {

                min=prices[i];

            }

            if(prices[prices.length-1-i]>max)

            {

                max=prices[prices.length-1-i];

            }

        }

        else

            break;



    }



    System.out.println(max-min);

}



public static void main(String args) {

    // TODO Auto-generated method stub



    Scanner sc = new Scanner(System.in);

    String prices=new String[10];

    String input=new String();

    input=sc.next();

    prices=input.split(",");





    maxprofit(prices);



}



}

input.split(",") returns a new array. So after you assign that array to your input variable, input references the new (larger) array instead of the original 10 elements array.

Both of these initializations are pointless:

String prices=new String[10];

String input=new String();

Instead, you can write:

String input = sc.next();

String prices = input.split(",");
