Find the Maximum

Write a function which finds the maximum number in an array or numbers.


This problem ensures you know how to implement a loop and search in an array.

public class FindMax {
  /** @param a an array of integers of length > 0
      Returns the maximum integer in a */
  public static int findMax(int[] a){
    int theMax = a[0];
    for (int i =0; i < a.length; i++){
      if (a[i] > theMax) {
        theMax = a[i];}
    }
    return theMax;
  }

  //Do some unit testing
  public static void main (String [] argv){
    int[] a = new int[5];
    a[0] = 1; a[1] = 3; a[2] = 2; a[3] = 7; a[4] = 5;
    System.out.println(findMax(a));
  }
}
