Question

Java Lab Assignment

Write a method named findMax. The method will take an array of doubles as an argument, and it will return the largest value in the array. (Note, you will have to create a new array of doubles) .

method must be well documented using JavaDoc, example:

/** * The find method checks if the target in the array

* @param String [] a - array of Strings

* @param String t - value to be searched for

* @return true if the String t is found, false otherwise

*/

Answer 1

public class FindMaxTest {

    /**
     * The findMax method finds and returns the maximum value in array
     *
     * @param arr - array of doubles
     * @return the largest value in the double array
     */
    public static double findMax(double[] arr) {
        double max = arr[0];
        for (int i = 0; i < arr.length; i++) {
            if (arr[i] > max)
                max = arr[i];
        }
        return max;
    }

    public static void main(String[] args) {
        System.out.println(findMax(new double[] {4, 9, 1, 2, 6}));
    }
}
