Java Assignment To Get User Input And Display ZIP Codes And Populations
Oct 7, 2014
URL....So the problem is that when I type in "PA" it will display about 24 Zips and Populations before it stops. The problem is in the ZIPs file. It goes down the list and then takes the Zip from the Zips file to the Zips in the Population file and displays the Population. It will go to population 513 and stop. Reason being, there is no ZIP code in the Population file to display a population. The loop then stops. How can I get the program to skip over the zip code when there is no corresponding ZIP code in the other file and continue showing the other Pops..Here's what I currently have completed:
import java.io.File;
import java.io.FileNotFoundException;
import java.util.Scanner;
public class Population {
//Declaring global variables.
Scanner fileScannerZip, fileScannerPop, inputFile;
private String lineZip, linePop;
int invalidZip;
[code]...

I have returned with yet another problem but I think this one might be a bit easier to fix.
So the whole MO of this program is to take user input, and display the sum of the digits of the number they entered. I am supposed to do this by utilizing methods. So far this is what I have and when I compile it tells me that it "cannot find symbol", which I don't understand as I define what "m" is in the for loop. The other error is that it says:
"Exercise6_2.java:22: error: incompatible types: possible lossy conversion from long to int
return result;
^
I don't understand why it's giving me this error nor do I understand why result seems to inherently be an int. (Also the public static int sumDigits(long n) method was given to me by the book so that is what I am supposed to use).
import java.util.Scanner;
public class Exercise6_2 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter a integer");
long n = input.nextLong();

I've done a lot of hardwork for this assignment but I don't know what's why the second textfield which is for output is blank.
All I want is to get the input from user in textfield a and display it in textfield b in lower case.
public void KeyPressed (KeyEvent ke) {
String letter2="";
if(ke.getKeyCode()==KeyEvent.VK_A)
{
letter2=letter2+"a";
btextfield.setText(letter2);

I understand the stack part of it, just not the loop, specifically how you give the user more than one option to input.
Implement a printer driver that handles incoming print jobs. The driver will behave in the following manner:
- Loop giving the user the following options: ADD print job, DELETE latest print job, and
QUIT
- Recording the following information from each job: computer name, document name, and
number of pages
- When the user chooses to ADD, add a new print job to the top of the stack
- When the user chooses to DELETE, pop off the latest print job and output to the screen
which job has just been deleted
- When the user chooses to QUIT, output the print jobs still in the stack (in order from top
to bottom)
- Output must include all relevant information for each job.

Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".

I want to write a java program which displays to get the GPA of a student as a keyboard input. Then display the class of the degree according to the following criteria using a switch-case statement (if-else statements cannot be used). If the user insert an invalid gpa you should display a message Invalid GPA.
gpa ≥ 3.50 First Class Hons
3.49 ≥ gpa ≥ 3.00 Upper Second Class Hons
2.99 ≥ gpa ≥ 2.50 Lower Second Class Hons
2.49 ≥ gpa ≥ 2.00 Pass
2.00 ≥ gpa Fail
Here is my code:
import java.io.*;
public class q7
{
public static void main(String[] args)
{
InputStreamReader ISR=new InputStreamReader(System.in);
BufferedReader BR=new BufferedReader(ISR);
[code]...
.But when I use Command console to run this it says: 1111.jpg. I also wanna know is there another way to do this with switch- case statements.

But when the user has typed in the name of a fruit (to reserve it) I'd like it to say 'Reserved' when the user then presses 'V' (to go and view all fruit)I have read Oracle Java Collections Arraylist and from my understanding I either have to code using the get method or equals method but I'm not too sure how to (I did try though)

This is the java code that I wrote for a password:
// java application that asks the user to enter a password
import java.util.Scanner; //program uses class scanner
public class password{
//main method used to execute java application
public static void main(String args[]){
//create scanner to obtain input from command window
[Code] ....
here is the output of the code when I run it :
entered the passwordreason
Try againPress any key to continue . . .
The code compiles without errors. The problem is when , I entered the actually password that I declared in my code, it doesn't output "You entered the correct password" but it instead outputs "Try again", which is supposed to be the output if you've entered the incorrect password. What did I do wrong?

I'm quite new to java programming, but eager to learn. I was wondering how to change actual java code, using user input. For example:
Java Code: int x = 0;
// Start the program and enter 3
// Now the code is
int x = 3 mh_sh_highlight_all('java');

I thought numeric literal were by default int or doubles, depending on if have a . and numbers after the But I wrote a quick test program as listed below. I understand the float float floatA = 5.5; failed to compile since 5.5 is a literal of type double and you are trying to assign this to a floag
What I am having problems with is byte byteA = 5; 5 is a literal of type int and this is being assigned to a byte and compiler should complain.The compiler does not allow two byte values to be added and assigned to a byte since the result of the addition is an int
class literalTesting{
public static void main(String[] arg){
byte byteA = 5; // allowed WHY I thought literal is an int and assigning int to byte
byte byteB = 10; // allowed

I am designing a program in-order convert Binary to Decimal values with added features:
Rejecting binary values longer than 32 bits
Prompting the user to make multiple entries after completing the binary to decimal conversion of their first entry. I was trying to code this in Nested For Loops, but I don't know if I've really done that.
Here is what i have so far.
public class BinaryToDecimal {
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
String binary;
int decimal=0b10, i, rem;
boolean isBinary = true;

Write a program that prompts the user for an input number and checks to see if that input number is greater than zero. If the input number is greater than 0, the program does a multiplication of all the numbers up to the input number starting with the input number. For example if the user inputs the number 9, then the program displays the following sum:
9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 362880
That's the question I'm getting and so far all I've got is
import java.util.Scanner;
public class Lab4Q3
{
public static void main (String[] args)
{
int keyboard;

I am creating a simple code in Java that replaces all tabs the user inputs with '*'. However, I am doing something wrong and I am not sure what. Here is what I have so far in Eclipse..
import java.util.Scanner;
public class ReplacingTabs {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
String s = "";
String s2 = "";
[Code] .....
There is an error with the s2 in the line String s2 = s.replace(' ','*');
I think I need to add String s2 to the loop but I am not sure how..

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.
// QR Code Generator
package qrcode;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JTextField;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;

Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
• The user wins the first prize if the user input matches all five digits in the lottery number in exact order.
• The user wins the second prize if the user input matches any four digits in the lottery number in exact positions.
• The user wins the third prize if the user input matches any three digits in the lottery number in its exact position.
• The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.
• The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.
and here is my code. I cant get it to print the right statements.
import java.util.Scanner;
import java.util.Random;
class Hw5 {
static int getPrize(int g1, int g2, int g3, int g4, int g5,
int u1, int u2, int u3, int u4, int u5) {
//code for determining the prize comparing (g1, g2, g3, g4, g5) to (u1, u2, u3, u4, u5)
if (u1 == g1 && u2 == g2 && u3 == g3 && u4 == g4 && u5 == g5)

I am creating 2 different java codes for encryption and decryption separately based on RSA algorithm. The codes also involve swings for GUI. The problem with these codes are that my string is getting encrypted but after decrypting it,i do not get the string rather i get string of random numbers and alphabets. I am posting both the codes.
Encryption code:
import java.math.BigInteger;
import java.util.Random;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class cipher implements ActionListener
[Code] ....
Now the decryption code
import java.math.BigInteger;
import java.util.Random;
import java.io.*;
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class decipher implements ActionListener
[Code] ....
The screenshots for respective codes are as attachments ....
