       iterativeSearch(anArray, st);
      
   //System.out.println(iterativeSearch(anArray, st));
   }

   public static <T> boolean iterativeSearch(T[] anArray, T number) {
      
      
       boolean found = false;
      
       int index = 0;
      
      
       while (!found && (index < anArray.length)) {
          
           if(number.equals(anArray[index])) {
              
               found = true;

public class Search{
public static void main(String[] args) {
Character [] anArray = {'a','b','c','d'};
System.out.println(iterativeSearch(anArray, 'd'));
System.out.println(iterativeSearch(anArray, 'e'));
}

public static <T> int iterativeSearch(T[] anArray, T number) {
boolean found = false;
int index = 0;
  
while (!found && (index < anArray.length)) {
if(number.equals(anArray[index])) {
found = true;
System.out.println("Element found at index: " + index);
break;
}
index++;
}

if(found == false)
return -1;
return index;
}

}
