Question

For some reason another programmer has asked you to write a function.

The function is called getWarYear ( ) It has one parameter , an integer.

if it is 1 return a random number in the range of 1914 to 1919.

if it is 2 return a random number in the range of 1938 to 1945.

Since the function is returning an year the data type of the return value is an integer.

Answer 1

import java.util.Random;

public class RandomYear {
   public static void main(String[] args) {
       System.out.println(getWarYear(1));
       System.out.println(getWarYear(2));

   }

   private static int getWarYear(int n) {
       int min = 0, max = 0;
       // setting min and max values based on given string
       if (n == 1) {
           min = 1914;
           max = 1919;
       }
       if (n == 2) {
           min = 1938;
           max = 1945;
       }
       // generating random number in range
       Random r = new Random();
       return r.nextInt((max - min) + 1) + min;

   }
}
