I am trying to concatenate two arrays but on on compiling it is showing
Java Code: import static java.util.Arrays.*; class Mergesort { public static void main(String...s) { Mergesort r=new Mergesort(); int x[]={1,2,3,4,5,6}; int y[]={9,8,7,15,14,13,12,11};
Write a program that declares and concatenates various strings. Declare strings for your first name, middle initial and last name, along with one for your address, city, state and zip. Make an additional string called firstLine, which will be a concatenation of first name, space, middle initial, period, space, and last name. Assign each of these strings a value, and then print the information in the following format:
First Line (First name Middle initial (period) Last name)
Address
City, State
Zip
For example:
John Q. Public
1234 Any Street
Cleveland, Ohio
44101
Now reassign the strings in the same program (Do not create a separately compiled program!) and repeat the printout for different information. When you are finished, your program will print out two groups as above.
The information should be placed into the seven separate strings, then a first line should be formed by concatenating first name, space, middle initial, period, space, and last name. The city and state line should be formed by printing city followed by a comma, a space, then the state (NOT by concatenation). This is so you can see different ways of making lines."
and what I want to do is simply run through a loop (Which I already made ) that will randomly just put this strings together. So if the loop runs once it will return something similar to
00001011001101000110
The thing is that I don't want to return such a number as an String, I want it to be returned as a long.This was one of my recent attempts
/* Contains the genes or possible solutions to the problem */ public class Genes { /* Each element is a binary number that corresponds to index number they have been assigned to, these are the possible genes * The last 4 elements in the array represent + - * / correspondingly */ private String[] encodedNumbers = {"0000", "0001", "0010", "0011","0100", "0101", "0110","0111","1000","1001","1010","1011","1100","1101"};
[code]...
What can I do ? I want them the values returned to be of the long data type, but I don't want the binary numbers to be added together. I just simply want them to be placed one next to each other at random patterns
import java.awt.*; import java.awt.event.*; import javax.swing.*; public class C1 extends JFrame { public C1() { JMenuBar b = new JMenuBar(); b.setBackground(Color.green); setJMenuBar(b); setVisible(true); } public static void main(String[] args) { C1 c = new C1(); } }
In my if statement on line 46 & 47 im trying to add the buttons to the screen if the player has lost and the "game over" screen have popped up. But the buttons aren't showing... what am i doing wrong?
I'm trying to show mysql data in JSF using this example [URL] .... . I figured out what <h:dataTable value="#{userBean.getUserList()}" var="u" border="1"> must be <h:dataTable value="#{userBean.userList}" var="u" border="1"> but getting error:

MyGraphics worked before I added a background but, even now when I take the background away it isn't showing up.
package com.snow.game; import javax.swing.*; import java.awt.*; class MyGraphics extends JComponent { //creating a class for graphics public void draw(Graphics g){ //calling Graphics making a new graphics (g) now you can use it to make objects g.drawRect(10, 10, 50, 50); //Draws a rectangle
I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:
1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error. 2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]
But it is giving 40. Code is as below:
class Base{ int value = 0; Base(){ addValue(); } void addValue(){ value += 10;
How do I write a program that shows the max and the min value of a float integer? like for example in order to get the max value of a long integer we type System.out.println(Integer.MAX_VALUE); How would I do that for a float integer?
I'm attempting to add a Jpanel in a JFrame but it isn't working out.
import javax.swing.JFrame; import javax.swing.JPanel; public class stepone { public static void main (String[]args){ JFrame frame = new JFrame("CSC LAB 12"); JPanel colorJPanel = new JPanel(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
I have three classes.. 1. panel class 2. frame class and 3. tester class...I am creating the objects like so but when I add button to panel then panel to frame I am not seeing the button. here is my code
import javax.swing.JButton; import javax.swing.JPanel; public class Panel extends JPanel{ private JPanel p; private JButton b;
But apparently i was wrong and all i get is an empty JFrame and no Dialog. I even added my own subclass of SwingWorker in case a SwingWorker had to be created in order for a progress monitor to exist. How can I make it show?
I am watching BrandonioProductions on youtube. His videos are pretty good, but he doesn't seem to get errors where I get them. Here is an example.
public class compareUnequal { public static void main(String[] args){ compareTwo(); } public static void compareTwo(){ String x = "david"; String y = "Notdavid"; if (!x.equals(y)){ System.out.println("Not equal"); } } }
It runs ok, but asked me to proceed when there is an error, but I can`t figure out where the error is!
We are asked to create a JDialog showing our database. I am able to show the database but i can't seem to position the heading panel, table and back button. My back button is also not showing up. Here is part of my code...
I am thinking of creating a quiz application and facing one problem.
On first question I don`t have to show previous button and on last question I don`t have to show next button.And for in between question I have to show both the buttons. . How can I do that in a JSP page.
Why is it not showing those months updated balance? I feel like I'm pretty close. I guess I should specify that this is supposed to calculate monthly interest for one account and quarterly interest for the other. This is what the output should look like.
I had to make a table showing different values for converting kg to lbs and I'm confused because when it compiles, some of the decimals show correctly and some of them show with several 0's added on with another number on the end. I've tried to do math.random, but I'm not sure how to tie it in with my program.
//1 kg = 2.2 lbs public class kg_to_lbs { public static void main(String[] args) { //not sure if values are needed.. int kg = 1; double lbs = 2.20; //Table title
Is it possible for a rectangle with dotted side be shown when dragging the mouse on a component?Just something like the one in the attachments, usually occurs in some graphics/pictures software.
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; public class JLeftOrRight {
