Solution Review: Finding Max in an Array

Understand how to write a generic Java method that finds the maximum value in an array by using the Comparable interface. This lesson helps you apply generics for flexible, type-safe code that works with various data types while mastering core concepts of comparison and traversal.

We'll cover the following...

Given solution

Java
class FindMax {

    public static < T extends Comparable < T >> T array_max(T data[], int n) {

        T max = data[0];

        int i;

        for (i = 1; i < n; i++) {

            if (max.compareTo(data[i]) < 0) {

                max = data[i];

            }

        }

        return max;

    }

    public static void main( String args[] ) {

        Integer[] inputs1 = {2,8,20,3,4};

        Double[] inputs2 = {2.7,3.8,5.5,6.7,9.7};

        System.out.println(array_max(inputs1,5));

        System.out.println(array_max(inputs2,5));

    }

}
