Answer 2

A java program that generates random string called str of 10 characters from the English alphabet (lower and upper case) and then find the longest sequence of characters from str that is also a substring in your First Name called matchStr.

// Java program generate a random AlphaNumeric String

// using Math.random() method

public class RandomString {

static String getAlphaNumericString(int n)

{

 // chose a Character random from this String

 String AlphaNumericString = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"+ "0123456789"+"abcdefghijklmnopqrstuvxyz";

 // create StringBuffer size of AlphaNumericString

 StringBuilder sb = new StringBuilder(n);

 for (int i = 0; i < n; i++) {

  // generate a random number between

  // 0 to AlphaNumericString variable length

  int index

   = (int)(AlphaNumericString.length()

     * Math.random());

  // add Character one by one in end of sb

  sb.append(AlphaNumericString

     .charAt(index));

 }

 return sb.toString();

}

public static void main(String[] args)

{

 int n = 10;

 // Get and display the alphanumeric string

 System.out.println(RandomString

      .getAlphaNumericString(n));

}

}
