Solution

HI, Please find my implementation.

To add: use add method

To search: use contains method

public static HashSet<Integer> doHashSetSearchGreatest(int numItems) {

System.out.print(\"doHashSetSearchGreatest: \");

HashSet<Integer> set = new HashSet<>();

// TODO Write code that adds integers 0 through (numItems - 1)

// to set.

for(int i=0; i<numItems; i++)

   set.add(i);

long startTime = getTimestamp();

//long startTime = System.currentTimeMillis();

// TODO Write code that checks if integer (numItems - 1)

// is a member of set.

if(set.contains(numItems-1))

   System.out.println((numItems-1)+ \" is a memeber of set\");

else

   System.out.println((numItems-1)+ \" is not a memeber of set\");

   long endTime = getTimestamp();

//long endTime = System.currentTimeMillis();

long totalTime = endTime - startTime;

System.out.println(totalTime);

return set;

}
