class ForInLoop
{
    public static void main(String args[])
    {
    int a[ ]=new int[10];
    a[0]=1;
    a[1]=2;
    a[2]=3;
   
    a[4]=5;
    a[5]=6;
    a[6]=7;
    a[7]=8;
    a[8]=9;
   

   
    for(int i:a)
    {
    System.out.println(i);

    }
    }
}

conclustion:
---If there is no element at last or in-between It will gives 0 at that place
---ex..there is no element at index 3 then a[3]=0;
