Convert String To Integer
May 21, 2014I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:
Java Code:
public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

Program To Convert A Base 10 Integer To Any Base 2 - 16
May 5, 2013I am writing a program to convert a base 10 integer to any base 2-16. Here are the terms:"The method is to convert the decimal value the user selected into whatever base the user selected and print the converted value one place value at a time by using an index into an array of characters 0-9 amd A-F that is initialized to contain those characters.In the method you will find the largest place value (i.e. power of the base) that will divide into the decimal number.
Then you can set up a loop that will operate from that power down to and including the 0th power to determine how many times each place value goes into the decimal number. Using the loop counter, index into the character array to print the character that corresponds to the quotient number and then subtract the product of the place value and the quotient from the decimal number. With the power (loop index) decreased, repeat until you finish the 0th place value. Here's what I have so far:
import java.io.*;
import java.util.Scanner;
public class ConvertIt
{//start program
public static void main(String[] args)
{//start main
Scanner input = new Scanner(System.in);
System.out.println("Enter a positive integer from 0 to 10000.");
int number = input.nextInt();

Getting Rid Of Asterisks
Mar 19, 2014This is my code so far which is correct my only problem is that I have to make it so there doesn't become more than 50 asterisks on a line and I don't know how to do that I know the code is something divided by 50 but I dont understand where I would put it.
so instead of this
************************************************** ******************(pretend it was 100 asterisks)
it would be
****************************************(x<50 asterisks or 42)
import java.util.*;
public class Graph {
private int [] counter;
public Graph(int x) {
counter=new int[5];

Bar Chart With Asterisks
Oct 12, 2014I need to make a loop that prints out a certain number of asterisks, depending on the random number generated (includes 0-24, not including 25). I'm just in basic java programming and am stuck on this task.
These are the directions given to me:
Write a loop to do the following tasks 10 times:
-Generate a random number in the range of 0 to 24 and store in an int variable named: score
-Write loop to print a bar of asterisks proportional to the value in score :
For example: , if value stored in score is 8, the bar chart should like as follows: (value of score spaced by a tab ( ) and a series of 8 asterisks in one line)
8 ********
//end of the loop
I've tried looking for other questions like this, but this one is a random number, with no input. Yes, I know there are easier ways, but my professor is extremely picky with everything.
This is what I have so far:
public class PA5LoopsA {
public static void main(String [] args) {
//Declare variables
int score;
//Generate random number between 0 and 24
score = (int) (Math.random() * 25);
[Code] ....
Clearly, none of my formatting went through...yes, I know how to space everything out!
Bar Chart With Asterisks?
Oct 19, 2014Here is the assignment instructions:
Overview: Use the Eclipse Java environment to create and test a program using methods that will display a bar graph.
Specifics: This assignment is an extension of the Module 5 activity, the first bar chart (asterisk) display program. You should also make use of the Bar Chart printing program of Chapter 6 (Fig. 6 in the textbook, p. 217).
Your program should use methods to accept input from the keyboard, store it in an array, and use that data to display a bar graph.
Pseudocode for the program might look like the following.
Main
declare an array of integers
get the number of asterisks in each bar
print the bar graph
get the number of asterisks in each bar
declare a Scanner input object
declare an array to fill and return
[code]....
Problem is I cannot get it to display the number of asterisks I enter as input.
Displacing A Shape Made Of Asterisks
May 5, 2014I'm making a program that prints arrows of varying tail length, head width, and displacement.The shape algorithms are working properly, but the displacement isn't working. The first arrow has zero displacement, and the second one is supposed to be bigger and start the print at 10 spaces right and 5 spaces down from the default, but it's not working. I tried changing the displacement settings of the first arrow, and no changes happened, so I know that the positions aren't registering properly in general. How to pass the xAdj and yAdj (displacement) values? I think I have the empty space formula set up, but it's still not running.
Driver:
public class Driver
{
//default values
public static final int Arrow_Default_xAdj = 0;
public static final int Arrow_Default_yAdj = 0;
public static final int Arrow_Default_tail = 5;
public static final int Arrow_Default_width = 5;

Draw Square With Asterisks (for Loops)
Apr 21, 2015So currently I'm trying to learn how to draw a square with asterisks based on the input I give for it's sideLength.
So if I have a Square(5) it should draw a 5x5 looking like this:
*****
*****
*****
*****
*****
but then in the main method, it should draw multiple squares of given sizes, so say 5, 6, and 7. Making a square for each of the given numbers. This is what I currently have so far ....
class Square {
int sideLength; Square( int size ) {
sideLength= size;
} int getArea() {

Printing Asterisks Shape In Java
Mar 17, 2014I am supposed to Write a program that prints a shape similar to the following shape. Maximize use of loops and minimize use of print statements.
.....*
....**
...***
..****
...***
....**
.....*
(without the "...")(i couldn't get it to stay in shape)
This is what i got so far:
Java Code: package assignment7;
public class Exercise3
{
public static void main (String[] args)
{
for (int count =0; count < 4; count++)
{
for (int j=0; j < count+1; j++)
[Code] ....
Tthis compiles to:
*
**
***
****

How do i center it to create the shape?

Convert To Lambda
Feb 13, 2015I am learning about Lambdas and am having a little difficulty in a conversion. I need to introduce a List into which the array supplied by the values method of the Field class is copied, using the asList method of the class Arrays. Then I need to convert the for loop with a forEach internal loop using a lambda expression as its parameter. The body of the lambda expression will be the code that is the present body of the for loop. I believe I have the List syntax correct ( List<String> list = Arrays.asList(data); ), but I am having a hard time on figuring out what to do with the for loop, or even where to start with it.
public AreaData(String... data) {
List<String> list = Arrays.asList(data);
/* Assert to check that the data is of the expected number of items. */
assert data.length == Field.values().length : "Incorrect number of fields";
for( Field field : Field.values() )
