You may assume that all values are positive. First figure out the maximum value. That value's bar should be drawn with 40 asterisks. Shorter bars should use proportionally fewer asterisks.

The problem is that all this code does is print 1 line of *'s and what seems to be thousands of them
I am attempting a programming exercise to display the values in the Fibonacci sequence from F0 to F15. I understand the concept, but, for some reason my equation is simply creating a resulting string of numbers that simply increase by 2's. As, I know it is supposed to be the sum of the previous F and the F that precedes that one to total the new F number. It seems so simple yet I seem to be far off. As usual, I have worked my code for your review.
/* * This program calculates the "Fibonacci sequence." * A "sentinel" is used to limit the extent the calculation. */
import acm.program.*; public class bookFibonacciTest2a extends ConsoleProgram { /* Specifies the limit value of the calculations */ private static final int SENTINEL = 16; public void run() { println ("This program display Fibonacci sequence numbers 0 - 15.");
Write a program that reads an integer and displays, using asterisks, a filled diamond of the given side length. For example, if the side length is 4 the program should display.
* *** ***** ******* ***** *** *
I have it where it displays the top half of the diamond. But i cannot figure out how to get it to draw the bottom half.
import java.util.*; public class E616 { public static void main(String[] args) { Scanner input=new Scanner(System.in); System.out.print("Enter number of rows. "); int N=input.nextInt();
I use JTable and JScrollpane in my java application, and I would like for every selected row in the scroll pane, the pie chart to be made for the values in % that the row contain.
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:
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.
I want to develop a dynamic scheduling application that I hope to use at work, but I have some questions about the design approach since this is my first undertaking of this kind of project.
The purpose of the application is to display a chart showing the lesson times for a particular teacher and her students.
Here's are more important details:
-The chart displays the current day's schedule. -The top row displays the teacher's name. There are at least 4 teachers each day. -The leftmost column shows the times (from 3:00 to 8:00). -The table is filled with the names of the students.
My current problem is deciding on the best approach to storing this data containing the teacher and her students and times. I should also note that there are about 500 students and around 20 teachers (i.e. the dataset is small). Is this a problem solved using a database and JDBC or could I just write the data to file? Are there other approaches that would solve this problem?
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.
So I'm trying to write a program that takes in 20 numbers and computes their average and I'm supposed to use a while loop to read the values and to make sure that all the numbers are positive. My while loop is set up and does all the math correctly but I have completely forgotten how to taken 20 numbers from the user all at once and then run them through the while loop.
HERE IS MY CODE SO FAR:
public static void main(String[] args) { int num = 100; int count = 0; int total = 0; while (num >= 0 && count < 20){ if (num %2 == 0){ total += num; count++; } } double avg = total/20; System.out.println("The Result Is: " + avg); }
i am trying to assign unique values to nodes read from XML file.. eg: consider this XML file:
<breakfast_menu> <food> <name>Belgian Waffles</name> <price>$5.95</price> <description> ...Strong Belgian waffles...</description> <calories>650</calories>
[code]....
now assigning these nodes "a unique value" has to be done following the LSDX labelling pattern i.e:
To the document element we first give an “a”.As there is no parent node for the document element, we assign “0” at the front of that “a” . “0a” is the unique code for the document element (breakfast_menu). For the children nodes of “0a”, we continue with the next level of the XML tree which is “1” then the code of its parent node which is “a” and a concatenation “.” . We then add a letter “b” for the first child, letter “c” for the second child, “d” for the third child and so on.Unique codes for children nodes of “0a” shall be “1a.b”, “1a.c”, “1a.d”, etc.Hence foe the above given XML the mapping would look something like this:
0a breakfast_menu 1a.b food 2ab.b name 2ab.c price 2ab.d description 2ab.e calories 2ab.f chef 3abf.b chef1 3abf.c chef2 1a.c food 2ac.b name 2ac.c price 2ac.d description 2ac.e calories 2ac.f chef 3acf.b chef1 3acf.c chef2

right now i am using SAX parser to read xml and get the nodes in their hierarchical order..now the problem is that i have to assign these specific value to their respective nodes using java.
Pass each index each time to a method returning all rows but getting stuck with DS to use. I think ArrayList wont suffice since i need separated data. Should i use a 2D array? Do i need to read and store data in a DS in order to achieve the goal?
2) Should i make 3 different classes with getters and setters for authors, book and magazine?
So I'm trying to read 11 values from a text file, each value on a separate line. The first value I use as loop control to run through calculations on the other ten and finally output both the numbers and the calculations to the console and an output file. I'm not getting a compiler error or a runtime error but my loop seems to stop after reading the first line. It also doesnt seem to be writing to my output file but does create it when I run the program. This is what my text file looks like
import java.util.*; import java.io.*; public class assignment7scratch { Toolkit_General toolKit = new Toolkit_General(); public static void main (String[]args)throws IOException
[Code] .....
so I dont get an error but this is what my output looks like
----jGRASP exec: java assignment7scratch
This program reads a list of values representing number of miles driven by individuals. It will output the dollar amount their rental cars cost.
Number of miles traveled on the left as well as amount reimbursed on the right
----------------------------------------------- Miles Driven Amount reimbursed 150.427.072
----jGRASP: operation complete.
it also doesn't write anything to my output file, though it does create one.
I am trying to read numeric values from a text file into an array. This is what i have so far but when i compile it, it doesn't run and give me a result.
import java.io.File; import java.io.FileNotFoundException; import java.io.IOException; import java.io.PrintWriter; import java.util.Scanner; public class question2_17110538 {
I need to break it and #numbers in braces are assigned to string array and they should cal by one by one. similarly next level on calling #166 same operation should perform
{#166=ADVANCED_FACE(",(#165),#129,.F.);}
like this 8 levels were there, finally at each level the Calling number should display in JTable.
I am writing a program that accepts input from the user, I want default values displayed before the input values.
Java Code:
public surfboards() { surfboardType = "Type not assigned"; shaperName = "Shaper not assigned"; constructionType = "Construction Type not assigned"; surboardSize = 0D; } mh_sh_highlight_all('java');
I can get the output to display as shown below
(THIS IS WHERE I WANT DEFAULT CONSTRUCTOR DISPLAYED. Currently not displayed)
Type not assigned Shaper not assigned Construction Type not assigned 0 Feet
(THIS IS WHERE I WANT DEFAULT CONSTRUCTOR DISPLAYED. Currently not displayed)
input:
Java Code: Enter Surboard Type: test Enter Shaper Name: test Enter Surfboard Construction Medium: test Enter Surfboard Size: 6.5 mh_sh_highlight_all('java');
I am just displaying my values in different ways and I can't seem to get my values to display one at time on new lines. I dont know why that isn't compiling. The part i am having trouble with has the "Not Working" tag in the code.
[highlight=Java] //Trying to figure out how to use /n public class Test { public static void main(String[] args) { int gold= 5; int silver= 3; int bronze= 1;
So I was going to try to create a program that prompts input and creates a file (That didn't exist before) with that input as name.Then, the program prompts inputs after stating questions such as 1 + 1, then if the user inputs an answer, put "Question # = Correct "or" Wrong.Code SO Far:
Java Code:
import java.io.BufferedReader; import java.io.File; import java.io.InputStreamReader; public class File_Read { public File_Read() {//File_Read is the Interactive object
[code]....
So that it puts the Correct or Wrong into the file.
The program contains username and password which on submission checks with the database if the details entered are right or wrong....on right details it Displays Welcome (name) and (lastname) parameters from database.
I am new to jsp .i created a wepage in jsp. That's i need to create dynamic textboxes in jsp and want to display the values of the textbox in next page.
I've written a die program, and i want the user to type any key in order to continue, how do i achieve this ?
I have already created a Die class, i just want to implement the main method now.
PHP Code:
package test;
/* This program demonstrates the use of a user-defined class
public class RollingDice { // Creates two Die objects and rolls them display the values. public static void main (String[] args) { Die die1 = new Die(); System.out.println("Roll the die ") } } mh_sh_highlight_all('php');
What should i add after System.out.println, So that the user types (any key, or types "Enter" for example, for the die to roll). i dont want the die to roll by itself i Want the user to interact with the program in order for it to roll.
