    copied!<p>I'm trying to create a program which contains a generic method, which contains a type parameter. It should return an instance of the class Pair. I'm not sure how i can return a Pair. The code i have is below:</p> <pre><code>public class MinMaxArray { public static &lt;ArrayType extends Comparable&lt;ArrayType&gt;&gt; ArrayType getMinMax(ArrayType[] anArray) throws IllegalArgumentException { try { ArrayType resultMin = anArray[0]; ArrayType resultMax = anArray[0]; for (int index = 1; index &lt; anArray.length; index++) if (result.compareTo(anArray[index]) &lt; 0) result = anArray[index]; if (result.compareTo(anArray[index]) &gt; 0) result = anArray[index]; return resultMin; return resultMax; }//try catch (ArrayIndexOutOfBoundsException e) { throw new IllegalArgumentException("Array must be non-empty", e); } catch (NullPointerException e) { throw new IllegalArgumentException("Array must exist", e); } }//getMinMax }//class MinMaxArray </code></pre> <p>Pair class Code:</p> <pre><code>//Two onjects grouped into a pair. public class Pair&lt;FirstType, SecondType&gt; { //The first object. private final FirstType first; //The second object. private final SecondType second; //Constructor is given the two objects. public Pair(FirstType requiredFirst, SecondType requiredSecond) { first = requiredFirst; second = requiredSecond; }//Pair //Return the first object. public FirstType getFirst() { return first; }//GetFirst //Return the second object. public SecondType getSecond() { return second; }//GetSecond }//class Pair </code></pre> <p>I'm not sure how i can get the resultMax and resultMin to return as a Pair. Thanks for the help.</p>
