Introduction to Java programming
You will create a secure password.
You program must dynamically determine the last character from the first name. Do not hardcode the number.
// PasswordGenerator.java
import java.util.Random;
import java.util.Scanner;
public class PasswordGenerator {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
Random rand = new Random();
// range of numbers from low to high
int low = 10;
int high = 99;
// reading first name and last name
System.out.print("Enter first name : ");
String fname = sc.next();
System.out.print("Enter last name : ");
String lname = sc.next();
// generating random number
int randNum = rand.nextInt(high-low) + low;
// extracting last character from first name and converting to upper case
String lastChar = Character.toString(fname.charAt(fname.length()-1)).toUpperCase();
// extracting first 3 characters from lastname
String first3Chars = lname.substring(0,3);
String password = lastChar + randNum + first3Chars;
System.out.println(fname +" "+ lname+"'s password is : \""+password+"\"");
sc.close();
}
}
Output:

in a java application need to create an application which prompts the user numerator and denominator values then show the result of the division. The application will use exception handling to verify the user has entered valid input and will continue to prompt the user for input as long as the value they enter is invalid. Once the user has entered valid numerator and denominator values, the result is shown and the application exits. had some issues when I entered letters instead of...

JAVA PROGRAMMING File Name You can not just take the file and send it. When Polycarp trying to send a file in the social network "Codehorses", he encountered an unexpected problem. If the name of the file contains three or more "x" (lowercase Latin letters "x") in a row, the system considers that the file content does not correspond to the social network topic. In this case, the file is not sent and an error message is displayed. Determine the...
Your task for this project is to write a parser for a customer form. You need to develop a Java application using Parboiled library.
