Example 9-10 further illustrates how the method largest can be used in a program.

EXAMPLE 9-10

//Program: Largest of a set of numbers

import java.util.*;

public class LargestNumber
{

public static void main(String[] args)
{

double [] numberList = {23, 45.5, 89, 34, 92.78,
36, 90, 120.89, 97, 23,
90, 89}; //Line 1

System.out.println("Line 2: The larger of 5.6 "
+ "and 10.8 is "
+ largest(5.6, 10.8)); //Line 2

System.out.println("Line 3: The largest of 23, "
+ "78, and 56 is "
+ largest(23, 78, 56)); //Line 3

System.out.println("Line 4: The largest of 93, "
+ "28, 83, and 66 is "
+ largest(93, 28, 83, 66));

//Line 4

System.out.println("Line 5: The largest of 22.5, "
+ "12.34, 56.34, 78, "
+ "\n "
+ "98.45, 25, 78, 23 and 36 is "
+ largest(22.5, 12.34, 56.34,
78, 98.45, 25, 78,
23, 36));

//Line 5

System.out.println("Line 6: The largest "
+ "number in numList is "
+ largest(numberList));

//Line 6

System.out.println("Line 7: A call to the method "
+ "largest with an empty \n"
+ " parameter "
+ "list returns the value "
+ largest()); //Line 7
