I have a vector
I try to print out the smallest number After compiling I get this messege: Arrays index is out of bound Exception.
what's the problem?

Code:

class VectorTest{
     public static void main(String[]args){
     	  int smallestvalue=Integer.MAX_VALUE;
     	  int lastvalue;
     	  int currentvalue;
     	  int []v={5,3,6,0};
     	  int i=0;
     	  while(i>=0){
     	         currentvalue= v[i+1];
                 lastvalue= v[ i ];

     	      if(current>last){
     	          smallestvalue=lastvalue;
     	        }else{
     	        smallestvalue=currentvalue;
     	     }
     	   i++;
         }	
              System.out.println(smallest);
   }
}
