Java Arrays: Finding Unique Numbers In A Group of 10 Inputted Numbers

Question

I\'m at a loss here.

I have this homework assignment where I have to enable the user to input 10 numbers, place them in an array, and figure out which inputted numbe

Answer 1

Instead of an array of input values, put them in a Set of Integers. Sets, by definition, store only unique values. If you add 3 'foos', there will be only one 'foo' in the set.

// Add this to your top-level loop
Set uniqueValues = new TreeSet;
uniqueValues.add(number);

// Add this after the loop to write all unique values on one line
for (Integer value : uniqueValues) {
  System.out.print(value.toString() + " ");
}

// Now end the line.
System.out.println();
