Question

Write program#1 upload .java file. #1 Write a java program that prompts the user for input using the Scanner class. First to enter their first name. Then prompts the user to enter their last name. Then prompts the user to enter their city. Then prompts the user to enter their state. Then prompts the user to enter their zip code. Concatenate first name and last name into full_name. Using String Class is optional. Use the String Class to replace zip code "0" with "N", replace "7" with "J". Use the String Class to make all the values upper case. Use the String Class to determine the length of full_name. Print on first line full_name and length of full_name. Print all on second line mailing address, including zip_string?

Answer 1

Save the program in a file names upload.java to run

___________________________________________________________________________
//Importing Scanner class for taking user input
import java.util.Scanner;
public class upload{
   public static void main(String[] args){
       Scanner input = new Scanner(System.in);

       //prompting user for input and saving inputs as variables
       //java.util.Scanner.nextLine() method scans the next token of the input as String.
       System.out.println("\n\nEnter First name:\n");
       String fName = input.nextLine();
      
       System.out.println("\nEnter Last name:\n");
       String lName = input.nextLine();
      
       System.out.println("\nEnter City:\n");
       String city = input.nextLine();
      
       System.out.println("\nEnter State:\n");
       String state = input.nextLine();
      
       System.out.println("\nEnter Zipcode:\n");
       //Integer.toString() method converts integers to string.
       //java.util.Scanner.nextInt() method scans the next token of the input as an int.
       String zipcode = Integer.toString(input.nextInt());
      
       //concatenating first name and last name
       String full_name = fName + " " + lName;

       //replacing 0 with N and 7 with J in zipcode.
       zipcode = zipcode.replace('0', 'N');
       zipcode = zipcode.replace('7', 'J');

       //convert all the values to upper case
       full_name = full_name.toUpperCase();
       city = city.toUpperCase();
       state = state.toUpperCase();
       zipcode = zipcode.toUpperCase();

       //finding the length of full name(including space between first and last name)
       int full_name_length = full_name.length();

       System.out.println("\n\nFull Name: " + full_name + " Length of Full Name: " + full_name_length);
       System.out.println("\nMailing address: " + city + ", " + state + ", " + zipcode + ". " + "\n\n");
   }//end of main() method
}//end of upload class
