OOP Program-7

(7) Assume a vehicle plate number consists of three uppercase letters followed by four digits. Write a program to generate a plate number. 

Program Code:

 import java.lang.Math;

public class OOP_07 

{

 public static void main(String[] args) 

 {

  int alpha1 = 'A' + (int)(Math.random() * ('Z' - 'A'));

  int alpha2 = 'A' + (int)(Math.random() * ('Z' - 'A'));

  int alpha3 = 'A' + (int)(Math.random() * ('Z' - 'A')); 

  int digit1 = (int)(Math.random() * 10);

  int digit2 = (int)(Math.random() * 10);

  int digit3 = (int)(Math.random() * 10);

  int digit4 = (int)(Math.random() * 10);

  System.out.println("" + (char)(alpha1) + ((char)(alpha2)) + 

   ((char)(alpha3)) + digit1 + digit2 + digit3 + digit4);

 }

}

Output:
