Printing JTable In Landscape
Jun 11, 2014
I'm having a small problem when attempting to print out a table using the JTable.print() method where it always seems to default to printing in portrait. I can change this in the print dialogue however I would much prefer if I could change this programmatically. I wont post the whole program as there is a lot of code(800+ lines) but here's the print method.
Code:
public void Printtable() {
boolean fitWidth = true;
boolean showPrintDialog = true;
boolean interactive = true;
JTable.PrintMode mode = fitWidth ? JTable.PrintMode.FIT_WIDTH
[Code] .....

If you print (eg a JTable) from Java/Swing and choose "Adobe PDF" as the printer, you get an Acrobat file. But the PDF isn't searchable because the text has already been rendered by Java before Adobe PDF gets to see it. Is there a way to make printing use a more high-level interface to the printer driver so that the text is left intact?

I am getting the following message when trying to print a JTable.
"Java(TM) platform SE binary has stopped working"
Here is the code:
try {
MessageFormat headerFormat = new MessageFormat("Page {0}");
MessageFormat footerFormat = new MessageFormat("- {0} -");
table.print(JTable.PrintMode.FIT_WIDTH, headerFormat, footerFormat);
} catch (java.awt.print.PrinterException pe) {
System.err.println("Error printing: " + pe.getMessage());
}

I need to compare two jtable and set the value from one jtabel to the other jtable.
jtable one consist of:
Unit ID Unit Name Access
ABC, Inc ABC Incorporate (checkbox) value = uncheck
CDE, Inc CDE Incorporate (Checkbox) value = uncheck
jtable two consist of:
Unit ID Access
ABC, Inc ABC Incorporate (checkbox) value = checked
CDE, Inc CDE Incorporate (Checkbox) value = checked
if comparing jtable one an jtable two has the same Unit ID then colum Access from jtable two value is set to jtable one become check based on jtable two.I did the code but did not work:
for (i = 0, jTable1.getrowcount(), i++) {
for (j = 0, jTable1.getrowcount(), j++) {
if (jTable1.getvalueAt(i,0) == jTable2.getvalueat(j,0)) {
jTable1.setvalueat(true,i,2)
}
}
}
above code i try did not make any changes.

I'm making a program where the user enters an ID number and can submit the amount of sales that person made for a specific product and write to a file. One of the things I have to do is making a running sum of the sales for each product for all people combined as well as an accumulation of the a persons sales every time he enters data. Everything seems to be working execpt my values like person1Total, person2Total...etx and product2Total.
When I try to write them to the file, they always come out at 0.0 even though they should be the sum of the indexes of the array sales.
import java.io.*;
import java.util.Scanner;
public class SalesReport {
// private static double p1Total, p2Total, p3Total, p4Total;
private static double product1Total, product2Total, product3Total, product4Total, product5Total;
private static double person1Total, person2Total, person3Total, person4Total;
public static void main(String[] args) throws IOException

I am trying to print out a list of usernames for my chat program. It currently works except for the username portion. The Server sends a specific line that tells the client to print it as a username. That line is name//name. For example, if the name of the client was Eric, then the server would send Eric//Eric to the client. The client will then receive the line through a buffered reader. However, my current code keeps getting an error at the i=input.substring... line. Its an IndexOutOfBoundsException: String index out of range: -1.
class ChatThread extends Thread {
ChatServer cServer;
String[] sentence;
int i;
public void run() {
String input = "Eric";
try {

So for fun I've decided to write a program that can keep track of a simple card game my friends and I designed. I've built a class for an array, that stores the basic stats of each card. I need to be able to access this array from another class, that will print the array information to a file, so we can easily keep track of who's cards have leveled up and their stats. The main class will also be using a random number generator to determine how much damage the attacker/defender deals and takes respectively. So far I have the random number generator built as well. I'm just having issues creating a print to file class and what I need to change in my array class to make it accessible by the other class that prints it to a file.
public class StartingStats {
public static void main(String[] args)
{
//Variable to use for how many spots in a stat array there are
final int statArray = 2;
[code]...
what I need to change so that a print to file class can access EACH array in this array folder. Also if any cookie cutter printToFile class I could use/borrow/change that'd be really useful, as I've never done any printing to file before. Also, the levels of each stat and exp will be changing so that's why I need a separate class to print so that I can call it when it's been updated so we always have the most up to date stats saved.

My array isn't printing. I have tried everything. I have tried putting a nested for loop in different methods but still no luck. I have also tried System.out.print but that prints random characters/numbers.
import java.util.Scanner;
public class Square
{
public static void main(String[] args)
[Code].....
^For some reason the site doesn't show the spaces between the *. It's supposed to be a 5x5 square.

I have a hashmap of the form HashMap <String, Set<String>>I am trying to create a method with one argument. The argument is a key for the hashmap, if it exists it should print out the key and the associated values. I'm falling over at even getting it to print the key, it keeps printing all the keys from within the hashmap as I don't know how to load the argument into it. I have this so far
Java Code:
public void printValue(String club)
{
boolean result = clubMap.containsKey(club);
if (result)
{
String key = clubMap.keySet(club).toString();
System.out.println(key );
[code]....

I've been working on the below code for a couple days in my spare time. Just a simple little text-based RPG. I'm brand new at programming and Java, so excuse the bad syntax. There's probably easier ways to go about what I'm trying to accomplish, but all we've learned so far in class is while loops and if statements. Anyways, the problem is that the statement "Really? Ten health points[...]yes or no?" in my code is printing twice.
int health = 0;
boolean enterHealth = false;
String verifyHealth = "";
boolean test6 = false;
boolean test7 = false;
boolean test8 = false;

Lets say in method 1 I want to print the numbers 1 - 10. Easy stuff. I then print that to the
PrintStream outFile = new PrintStream(new File ("output5_01")); I declared.
Now I'm in another methods, How do I print lets say 11- 20 without erasing the first methods printed results?
so my desired results would be
outFile
-------------------------------
(From 1st method) 1- 10
(From 2nd method) 11-20
As of now the second method always over writes the first. None of my books cover this and its very frustrating when the entire code is done but this won't let me write to the file

Im trying to make a question game, much like a spin off from Trivial Pursuit. In this code, I call classes to get a random number. This number determines what category the question will be from. Coinciding with this number, the "if" statements go and pull the questions and answers from an alternate class. My problem is that when I try and output what should be the question and the 3 answers, its outputs "null" for each String?
This is my first class, which is just the class for the player.

How do you replace negative zero value with a zero value when Printing results:
I want to remove the minus sign in -0.0000 and instead have 0.0000.
I am Printing coordinates and I do not want to have negative zero.
the coordinates are defined as double.
System.out.format(java.util.Locale.US," %.4f %.4f %.4f %.4f%n"xCur ,yCur,xNext,yNext);
0.0000 1.0000 -0.0000 0.0000

I am writing a Java permutation program, it takes in N and k and gives k amount of combinations based on N length.
That portion works, but the portion I have that does not work is when k is greater then 1, the array is then then printing strings out of index.
The perm algorithm ends on index - 1 for moving characters but then I push all those characters into an Array List, I would think I could print them off however I want from there but that is not the case. I'll include the minimum amount of code possible.
//permString = 1234 or something, it doesn't matter
//Use Case N = 4 k = 3, prints out 123,124,132,134 ect
//Use Case N = 4 k = 2, error index out of range but only on the printing function; the perm function doesn't take k and
//is based on length
//the "" is just an empty string
permNow("", permString);
}

I have a project to create an application where you can print all the detail to be written on a receipt (no more manual writing). I already have blank receipts. All I want to know is how to do that printing the details at exact position in my blank receipt. I'm starting to read about Jasper Reports but I don't know how it will work since most of its example are creating template.

why my code is not printing the matrix and sum?
The Java-program Matrix below first asks the user for the number of rows and columns in a matrix. After this the program asks for the values of the elements. Finally, program prints the elements of the matrix and their sum on screen. Your task is to create the missing methods. Check the example print to see how to modify the print. When printing the matrix, values on the same row are separated using tabulator.
Program to complete:
import java.util.Scanner;
public class Matrix {
public static void main(String[] args) {
int rows, columns;
Scanner reader = new Scanner(System.in);
System.out.print("Type in the number of rows: ");
[code]...
Write the missing methods here / Methods are written in the text box below.
Example output
Type in the number of rows: 3
Type in the number of columns: 4
Type in the element 1 of the row 1: 1
Type in the element 2 of the row 1: 2
Type in the element 3 of the row 1: 3
Type in the element 4 of the row 1: 4
Type in the element 1 of the row 2: 5
[code]...
Matrix:
1 2 3 4
5 6 7 8
9 10 11 12
Sum of the elements of the matrix: 78
my code
import java.util.Scanner;
public class apples {
public static void main(String[] args) {
int rows, columns;
Scanner reader = new Scanner(System.in);
System.out.print("Type in the number of rows: ");

I am learning while loops but the output I am getting is not what I want? My class:
public class BottlesOnWall {
public static void main (String[] args) {
int x = 99;
while (x > 1) {
System.out.println(x + " bottles on the wall!");
[Code] .....
The output I am getting is this:
99 bottles on the wall!
98 bottles on the wall!
97 bottles on the wall!
96 bottles on the wall!
95 bottles on the wall!
[Code] ....
I want it to stop on "2 bottles on the wall!" and then print "Only 1 bottle left on the wall!". How do I go about doing that? I have tried different variations of the condition (x>1), I have tried (x>5) but it still goes down to 1 bottle?

I am writing a program that has to do with ciphers and cipher shifts. The program itself works fine, but I am having trouble printing out the answers to JOptionPane. I know the basics of JOptionPane, but my problem is this:
Majority of my program takes place in a for loop, and resolves the cipher (it is a basic cipher program) 1 digit at a time. So, only the last DIGIT (I don't know how to convert a digit to a CHAR in JOptionPane) is printed to JOptionPane. Here is my code:
public static void main(String[] args) {
String cipher = JOptionPane.showInputDialog(null,
"Please enter a sentence or word that you wish to encode or decode. This program uses " + " a basic cipher shift.");
int answer = 0;
String upperCase = cipher.toUpperCase();
char[] cipherArray = cipher.toCharArray();

I'm trying to print sentences from a list which read in sentences from a text file. I'm able to get the program to print out the sentences in a numbered format corresponding to each sentence, but the first sentence in the list is always repeated, same as the next sentence. How can I print out the contents of a list in a numbered format (1. _ 2. _ 3._) without repeating sentences?
Here's my code:
package jacsim;
import java.util.Scanner;
import java.io.File;
import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;
import java.io.FileInputStream;
[Code] ....
The output looks like:
Input Sentences:
1:The cat in the hat
2:The cat in the hat The cat sat on the mat
3:The cat in the hat The cat sat on the mat Pigs in a blanket
Sorted Single Arrays:
I'm trying to make it look like:
1. The cat in the hat
2. The cat sat on the mat
3. Pigs in a blanket

Right, so I got this method that creates and sorts 2 lists. What I want to do is merge these lists into a third list, have it sorted, and then print the contents of the list. The problem is, I'm tired and I don't remember how I can print it.
import java.util.*;
public class MergeTwoSortedListWilson {
public void CHANGEME() {
// To do
ArrayList<String> aList = new ArrayList<String>();
aList.add("Banana");
[Code] ...
MergeTwoSortedListWilson.java:35: error: cannot find symbol
System.out.println(aList);
^
symbol: variable aList
location: class MergeTwoSortedListWilson
