I am using JSF 2 & Richfaces 4
My input text box should accept only 1 character.
<h:inputText id="empid" value="#{details.val}" size="1" />
Set the size as 1, still it showing more size in the screen.
Apart from size =1, any other place to set the size of the text box?
I noticed that all my stages can be resized to zero size regardless of their contained scene, which is very ugly. How do I keep them from doing that? Is there some sort of intelligent way to bind the stage's min size to the size of the scene so that no part of the scene is cut off?
View Replies View RelatedWhat I am creating is a clock. That goes round n round using "getcalendar". It's realtime, but the clock has a constant resolution of 800x800. I have carefully placed numbers from 1-12 on the clock using that resolution placing them pixel by pixel. Now if I resize the window, the clock resizes but the text, it fades away out of the screen because the resolution is too small.
This is how I draw them.
g2.drawString(six, 380, 750);
g2.drawString(twelve, 375, 70);
g2.drawString(nine, 30, 415);
g2.drawString(three, 725, 415);
g2.drawString(one, 570, 120);
g2.drawString(two, 690, 250);
g2.drawString(four, 685, 575);
g2.drawString(five, 570, 700);
g2.drawString(seven, 200, 710);
g2.drawString(eight, 80, 585);
g2.drawString(ten, 80, 235);
g2.drawString(eleven, 205, 115);
I understand why this is happening, obviously because the strings are in a certain place just can't understand how do I make them scaleable? Is there an universal formula? Or do I have to draw every string relevant to some mathematical equation regarding to the screen size.
For example : g2.drawString(twelve, diameter / 2, screenheight / 3);
I want to create 3 JTextFields in a row with all being of equal size.But my first Text field gets so wide than the other two.After adding each component at a time and seeing what causes the problem I realized that if I type a long text for the JLabel that's when this problem occurs.If I reduce the length of the text in the JLabel JTextFields get into the sizes I want. Here's my code
import java.awt.*;
import java.awt.event.*;
import java.lang.Math;
public class Calculator1 extends JFrame {
JTextField value1=new JTextField("0");
JTextField value2=new JTextField("0");

How can I stop the JTextFields changing size when I change the JLabel label1's text length...
I have a major problem. the text size is like 6 or 8 pt font and I can't read it. I'm trying to run a downloaded exe program which uses the jre7 which I had to download beforehand. the font size stays at 6 or 8 even if I try to change it in windows settings. it's a high res monitor on a lenovo yoga laptop. is there a way for me to edit the java code and manually change the font size?

I am writing a code based on the following question: "Write a method called arrayMin that accepts as an argument an array of numbers and returns the minimum value of the numbers in that array.Create an array to test your code with and call the method from main to print the min to the screen".

I'm almost finished with my assignment, I'm just having one small issue. The goal of this assignment is to have a user input as many values they want(up to 10) into a list. I need to store those in an array then figure out the sum of the numbers, the average, the Largest value, and the smallest value. I get everything to print out correct so far except for the Smallest number, it is returning a 0 every time. Here is my code:
import java.util.Scanner;
public class SimpleList{
Scanner in = new Scanner(System.in);
final private static int ARRAY_LENGTH = 10;
private float[] List = new float[ARRAY_LENGTH];
private int count = 0;

I am doing a homework assignment for a class I'm taking and writing a java program that finds the smallest and largest number in an array entered by the user. For some reason no matter what I enter as the smallest number it returns 0 as the smallest. I'm not sure what I have done wrong. Here is my code:
import javax.swing.JOptionPane;
public class MinimumAndMaximumJamesBulow
{
public static void main(String[] args)
{
int minimum = 0;
int maximum = 0;
[Code] ....
I have to return the minimum and maximum value entered by the user, so far the program returns the maximum but the minimum stays at 0. I assigned 0 to the min and max variables. I believe that is part of the problem, but why do I get an accurate answer on the max if both variables are assigned to 0?
int min = 0;
int max = 0;
int option = JOptionPane.YES_OPTION;
while ( option == JOptionPane.YES_OPTION){
String dataString = JOptionPane.showInputDialog("Enter an integer");
int data = Integer.parseInt(dataString);
if ( min > Integer.parseInt(dataString)) min = Integer.parseInt(dataString);
if ( max < Integer.parseInt(dataString)) max = Integer.parseInt(dataString);
option =JOptionPane.showConfirmDialog(null, "Continue?");
}
JOptionPane.showMessageDialog(null, "Minimum: " + min + "
Maximum: " + max);

I finished a game in Java and sent it to a friend. Launching the program in my computer worked just fine.
But he got this error : "Could not find the main classs: Main. program will exit"
My JRE version is the most updated one. His JRE was version 1.6. He updated his JRE, and the problem was solved.
This is a bit worrying for me, because as far as I know, 1.6 isn't a very old version of the JRE. It's not the most recent one, but not that old.
This is worrying because I'm planning on sending my game to a lot of friends, and trying to distribute it on the internet.
A lot of people don't have the most updated JRE. And they are mostly non-programmers, so I can't expect them to update to the newest version of Java upon downloading my game. They might not know what Java is, even though they got it on their computer, and upon receiving an error, they'll just give up on the game.
If my game wouldn't work with a significantly old JRE, that would be reasonable. It's part of the nature of working with Java. But the fact that a relatively updated JRE, 1.6, doesn't work with my game, is worrying.
*(Please note: My game isn't implementing anything "special". Swing and KeyBindings are the 'newest' additions to Java that I can think of inside my game)*.
In short, I'd like to know that my game works on most of the computers it tries to run on. Knowing that it doesn't work on a relatively new JRE, is worrying.
So I have two questions:
1. Is it normal, for a Java program, to have such "high" demands for the JRE version? Do a lot of Java games demand at least version 1.6 of the JRE? Is this common?
2. How can I find out the minimum JRE version requirement for my program? Is there a methodical way to do this, or do I just have to go through all the libraries I use in my game and figure out what's the JRE release version for each one?
I'm required to create a program that finds the minimum value in an Array of integers.
Here is my approach :
public class Person {
public static void main(String [ ] args){
int theArray[]=new int [10];
int result = 0;
for (int i:theArray){
if (i < Integer.MAX_VALUE)

I am trying to write a TreeMap that can hold a max of 20 colors and a minimum of 8. I have a while loop using pollLastEntry to limit the max but I can't figure out how to set the minimum. The hex number is the map's key and the color name is the value. I tried to use entrySet() and iterator to just double the size of the map but map can't have multiple keys with the same value. It also seems that to set a minimum would require some kind of further input(which I'm trying to avoid) of colors and their hex numbers.
//Method to hard code the colors into the map
public TreeMap<String, String> cm() {
//Color Map <Hex number, Color name>
//Uses a TreeMap to keep all the colors organized by key
TreeMap<String, String> cMap = new TreeMap<String, String>();
cMap.put("FFFF00", " Yellow");

I want to Write a program that calculates the minimum fixed monthly payment needed in order pay off a credit card balance.
the Amount is 3,500 the annual rate is 9.9%, the minimum payment is 2% a month. the fixed payment is 150.
By a fixed monthly payment, we mean a single number which does not change each month, but instead is a constant amount that will be paid each month.
The program should print out :
payment information:
new balance total .......
current payment due .......
if you make minimum payment (2%) you will pay of in .... months and you Will end up paying an estimated total of $........
if you make the fixed rate payment, you will pay of in .... months and you Will end up paying an estimated total of $........ and you will save $........
It does not calculate the maximum, minimum or average of the 10 numbers that the user is prompted to input.
My code:
import java.util.Scanner;
public class moretest {
public static void main( String [ ] args ) {
int total = 0;
int number;
int minGrade = 101;
[code]...
So I'm learning java from a website and I was tasked with creating a simple program which allows the user to enter a series of integers, then finally when they decide to input a non-integer the program will print the maximum and minimum values of the integers they entered. So for example if they entered 5, 4, 3 and 2 then enter a non-integer the program would output 5 (maximum value), then 2 on a new line (minimum value).
Here is my code:
import java.util.Scanner;
public class MaxMinPrinter {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int max = Integer.MIN_VALUE;
int min = Integer.MAX_VALUE;
[Code] ....
And this is what the output looks like:
Actual output
-------------------------------------------
Enter an integer: 5
- 10
-
- Enter an integer: -4
- 8
- -6
-
- Enter an integer: 11
- -1
-
- Enter an integer: q
- -1
- -6
When it's supposed to look like this:
Expected output
-------------------------------------------
Enter an integer: 5
Enter an integer: 10
Enter an integer: -4
Enter an integer: 8
Enter an integer: -6
Enter an integer: 11
Enter an integer: -1
Enter an integer: q
11
-6
1. Create a program that will return the maximum and minimum numbers in the elements of ONE-dimensional integer array. Save it as MaxMin_OneDim.java
2. Create a program that will return the maximum and minimum numbers in the elements of each row in a TWO-dimensional integer array. Save it as MaxMin_TwoDim.java
3. Write a program PrintPattern which prompt a user to enter a number and prints the following patterns using nested loops (assumed user entered number is 8 output is:)
1 .... 87654321
12 .... 7654321
123 .... 654321
1234 .... 54321
12345 .... 4321
123456 .... 321
1234567 .... 21
12345678 .... 1

I have been having difficulty with the weeks concepts in my online Java class, the program is to be as followed:
For this exercise you will implement a class called Pair, that represents a pair of two numbers.The Pair class should include the following constructor and methods:
CONSTRUCTORS
public Pair(double num1, double num2) -- Creates an object that represents a pair of double values
METHODS
public double getAverage() -- Returns the average value of the two numbers
public double getDistance() -- Returns the absolute vale of the distance between the two numbers
public double getMaximum() -- Returns the maximum value of the two numbers
public double getMinimum() -- Returns the minimum vale of the two numbers
Write a class called PairTest that tests your Pair implementation. The PairTest should prompt the user for the two values, create a Pair object with the values and then print the average, distance, maximum, and minimum of the pair. The input / output should look like the following:
Enter the first number: 5.5
Enter the second number: 3.0
Average: 4.25
Distance: 2.5
Maximum: 5.5
Minimum: 3.0
NOTE: For this exercise, your solution should not use any conditional statements. Instead you should use the methods provided by thejava.util.Math.
So far I have:
import java.lang.Math;
import java.util.Scanner;
public class Main
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
{
System.out.println("Please enter a value for the first number");

My program is reading my file, but its printing out weird cryptic numbers instead of the 1-10 that is in the file. But it uses the numbers in the file to get the Max Value and Total. Also I am receiving 0 for my Minimum Value but, 0 isn't even in the file, my lowest value is 1.
Java Code: /*
* Student Name: Irrelavent
*
* Description: This program will read from a text file and display its contents in an array format as well as the average of the numbers and the minimum and maximum value within the array and it will display the total of all the numbers added together.
*
* Input Variables:
*
* Desired Output:
* Total: 55
Average: 5.5
Minimum Value: 1.0
Maximum Value: 10.0
The data being used is: [1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0]
*/
[Code] ....
Output:
Numbers being used: [[I@55f96302]
---------------
Max Value: 10
---------------
Minimum Value: 0
---------------
Average: 0.0
---------------
Total: 55
I want 1 for my Minimum and I want 5.5 for my average, when I make 'average = total / numbers.length;' ---> 'average = total / (double)numbers.length;' I get 0.55. Also, as its obvious, my 'Numbers being used' section is messed up and I don't know whats causing this.
