gistfile1.java

public class Hello {
	public static void main(String[] args) {
		
		int[] array = new int[]{3,7,4,9,5,6,8,1,20,2}; 
		int largest = FindMax(array, 1, 20);
		System.out.print("The largest value = "+largest);
	}	
	
	public static int FindMax(int[] a, int start, int largest) {
	    if (start == a.length)
	        return largest;
	    else {
	        int last = (a[start] > largest ? a[start] : largest);
	        return FindMax(a, start + 1, last);
	    }
	}
