1.Write a program to produce a similar output for n characters, where n is a odd number. The below output is for n=7.
Java Code:
A B C D E F G F E D C B A
A B C D E F F E D C B A
A B C D E E D C B A
A B C D D C B A
A B C C B A
A B B A
A A
mh_sh_highlight_all('java');
I'm not sure why, but my program does not produce an output. It is supposed to output total charges.
/*This program provides the user with the price of their monthly internet service based on two inputs.The program asks users which subscription they have. The options are A, B, or C. This is the first input.
The program then will ask the user how many hours they used the internet for. This is the second input.Then, based on the package number, the program will compute their monthly bill. This is the output.
The program calculates the price based on the following prices:
Package A: For $9.95 per month, 10 hours of access are provided. Additional hours are $2.00 per hour.
Package B: For $13.95 per month, 20 hours of access are provided. Additional hours are $1.00 per hour.
Package C: For $19.95 per month, access is unlimited.*/

I'm having some trouble with getting this program to read an input of morse code and then produce an output of English. When typing in morse code for the phrase 'the string', the output looks something like this:
- .... .
t
h
... - .-. .. -. --.
s
t
r
i
n
The English-->Morse works just fine.
import java.util.Scanner;

I'm trying to produce a random number between 1 and 54 . I think this is correct
int i= (int)(Math.random()*54)+1;
I am working on a personal project and want to create a text editor to write my code. I am wondering how could I read the last input from the user and if say it was an open curly brace {, then like netbean's my editor will supply the closing curly brace. My java experience is limited but I have tried to read key board input and a few other options that did not work.

View Replies View RelatedI need to read the contents of file A, and B and store it in file C by joining the contents of A and B and also counting the number of letters/characters present in it.
I've come up with this so far.

I have been working on this for hours and cannot get it to work properly. The program is to count the number of characters contained in both strings and display the results. It is also to display the final statement, but only once. This version has a complete statement for each matching character.
import java.util.Scanner;
public class CountMatches {
public static void main(String[] args) {
String firstStr = ("");
String s1 = firstStr;
[Code] ....
The problem is i want to replace some string text with foreign characters, but JTextArea returns plainText.
For Example:
str = new String();
str.replace('e', 'é');
textArea.setText(str);
but textArea returns plainText.
I need the output to display like this:
At Billy Goat's Restaurant, the price of our good tasting Hotdog is $1.50.
But it is output display is like this:
At Billy Goat's Restaurant, the price of our good tasting Hotdogis 1.5
In the second array i use a double, is that not correct?
import java.util.Scanner;
public class FinalProject

public static void main(String[] args)
{
String[] FoodDescription = {"Hotdog", "Fries", "Hamburger", "Pepsi", "IceCream"};
double [] cost = {1.50,.80,2.25,1.00,.75};

The program should has the output depending the number I'll input. (The number should be from 1-9) . This is the program's output should be:
Input number: 4
Output:
# # # 1 # # # # #
# # # 2 # # # # #
# # # 3 # # # # #
1 2 3 4 5 6 7 8 9
# # # 5 # # # # #
# # # 6 # # # # #
# # # 7 # # # # #
# # # 8 # # # # #
# # # 9 # # # # #
(Example 2):
Input numbers: 8
Output:
# # # # # # # 1 #
# # # # # # # 2 #
# # # # # # # 3 #
# # # # # # # 4 #
# # # # # # # 5 #
# # # # # # # 6 #
# # # # # # # 7 #
1 2 3 4 5 6 7 8 9
# # # # # # # 9 #
(Example 3):
Input number: 5
Output:
# # # # 1 # # # #
# # # # 2 # # # #
# # # # 3 # # # #
# # # # 4 # # # #
1 2 3 4 5 6 7 8 9

I'm not asking the code to make this program, I have trouble to understand the algorithm to make this program ...
"Type Casting" .... So the question is "How am I getting a number with two decimal places as output?"
import java.util.Scanner;
public class SalesTax
{
public static void main(String[] args) {
double purchase, tax;
Scanner input = new Scanner(System.in);
System.out.print("Enter purchase amount: ");
purchase = input.nextDouble();
tax = purchase * 0.06;
System.out.println("Sales Tax: $" + (int)(tax * 100) / 100.0); +//this will give two decimal places??+
}
}
I've looked around a bit myself online (admittedly for only a few minutes) and have yet to come across a straight-forward object for date selection. Does Java offer something like that?what should be a simple task?
View Replies View RelatedRight now I have 12 methods, each roughly 40 lines long, and I am contemplating whether I should simplify some of the pairs (12 methods, but every other method is very similar to each other, so 6 pairs) into one method.
The main pro of simplifying them is that my class will be much smaller, right now its about 555 lines of code. However a con is that it might not be as straight forward, at first glance at least.
Here is what I am talking about. Two original methods that are very similar:
void rotateRightClockwise(int rotations){//rotates FRONTS's RIGHT! CONFIRMED
String a, b, c;//temp values
for(int i = 1; i <= rotations; i++){//confirmed
a = cube.cube[1][2].square[2];//3
b = cube.cube[1][2].square[5];//6
c = cube.cube[1][2].square[8];//9
[Code] ....
The only difference between these two methods, other than the last chunk for each method, is the I have to change the 2nd square bracket, [], values from lines 9-23 for cube[][]. That's it. So I am thinking of combining them into something like this...
private void rotateRight(int rotations, int x, int y){
String a, b, c;//temp values
for(int i = 1; i <= rotations; i++){//confirmed
a = cube.cube[1][2].square[2];//3
b = cube.cube[1][2].square[5];//6
c = cube.cube[1][2].square[8];//9
[Code] .....
And then after calling this similar method, I would finish off the last chunk from each methods, since they are too different (ie lines 26-38).
The reason why I ask this is because I am trying to build up my portfolio and I want to know if the employer would look at this and say "that was a good move by compacting your code" or "this is not that straight forward".
I've been working on a personal project again in Unit 3 of my text book and this time they want me to make a random phone number generator. Here's the actual directions:
"Write an application that creates and prints a random phone number of the form XXX-XXX-XXXX.
Include the dashes in the output.
Do not let the first three digits contain an 8 or 9 (but don't be more restrictive than that), and make sure that the second set of three digits is not greater than 742.
Think through the easiest way to construct the phone number. Each digit does not have to be determined separately."
With this assignment I came across 2 problems:
1. What I tried was that since the first 3 numbers have to be a random number with no 8's or 9's I tried doing this algorithm:
int first0, first1, first2, second, third, random0;
first0 = generator.nextInt (999);
random0 = generator.nextInt (8);
first1 = first0.replace('8', random0);
first2 = first1.replace('9' random0);
The problem is that Java won't allow me to generate random numbers this way. Are there any easier ways of generating numbers that doesn't contain specific number (such as 8 or 9 in this case?)
2. I was thinking about this throughout the whole project and what if I generate a number such as 27 (less than 3 or 4 digit number) rather than 3 or 4 digit numbers? How would it show 0027 or 027 instead of 27 for the phone numbers?
import java.util.Random;

Random generator = new Random();
int first0, first1, first2, second, third, random0;

Using JOptionPane,ask for 10 numbers from the user.Use an array to store the values of these 10 numbers.Output on the screen the number with the greatest value.
View Replies View RelatedWrite a program that prompts the user to input an integer and then outputs both the individual digits of the number and the sum of the digits.
Now I have a code for spacing out the integers, and I have a separate code for adding the digits. But I am not sure how to merge them together. Both of them work independently
Spacing code:

public class SumoftheIntegers

static Scanner console=new Scanner(System.in);
public static void main(String []args) {
int num1, test, rem;
int counter = 0;

Now the sum of the integers code:
import java.util.Scanner;
public class sum
{
public static void main(String[] args)
{
// Create a Scanner
Scanner input = new Scanner(System.in);
// Enter amount
System.out.print("Enter an integer: ");

private boolean collision = false;
private T mainEntity;

}
}
Why "this.mainEntity = mainEntity" is incorrect and also show me the correct way to achieve this?

View Replies View RelatedI have a question: I have a Java/JSP/JavaScript project that access back end Oracle database, and provide interaction through tomcat. After we deployed our project, I found one button does not generate necessary warning message from server, but when I deployed and tested our project on local PC, it does generate correct warning message. I am using the same IE, same tomcat version, and I am sure my container is pointing to the same database, and I am sure I using same version of project code by checking with GIT.
Here is the button that I click:

I cannot get the right output for my program. I need to get the total number of pennies in dollar amount for the output of Total Pay. This is my program. The directions are:
Write a program that calculates the amount a person would earn over a period of time if his or her salary is one penny the first day, two pennies the second day, and continues to double each day. The program should then show the total pay at the end of the period. The output should be displayed in a dollar amount, not the number of pennies. Do not accept a number less than 1 for the number of days worked.
import java.util.Scanner;
import java.text.DecimalFormat;
public class PenniesForPay {
public static void main(String[] args) {
int numDays;
[Code] ....
totalSalary should be total number of pennies / 100....However its not picking up only day 30 of pennies which is 536,870,912 pennies and then dividing it?

my program should provide following result: 3 because i have 3 characters which are similar in all the strings of the array(f,b,d).
