Answer 1

Answer:

for (scores.Entry<String, Integer> entry : scores.entrySet()) {

          int value=0; String key="Rambo";

          String k = entry.getKey();

           int v = entry.getValue();

           if (v>value)

           {

               value =v;

           }

           else

           {

               value=value;

           }  

       }

       for( scores.Entry<String, Integer> entry : scores.entrySet())

      {

        if( entry.getValue()==value)            

        System.out.println("Key = " + entry.getKey() + ", Value = " + entry.getValue());

      }

Explanation:

The above scores are an object of Map type.  And this is a parameter of findUopStudent function. So scores is a Map, and entry is an item. And we get its key and value. Now we compare each value using senteniel method and find the maximum value. Now we iterate through the scores using for the look and check the value of each entry against the maximum value found, and we print out the entry with maximum value. And that is the top student, which is required.
