Print With Straight Vertical Line To The Left Instead Of Right

Oct 27, 2014

How can I make this program print so the output looks like this ( ignore the - -- lines ):

--------1

-------21

-----321

---4321

-54321

Instead of:

1

21

321

4321

54321

Java Code:

public class c5e18c {
public static void main(String[]args){
int i;
int j;
for(i = 1; i<=6; i++){
for (j = i; j>=1 ;j--){
System.out.printf(j + " ");
}
System.out.println();
}
} mh_sh_highlight_all('java');
}

Print 10 Numbers Per Line

Feb 6, 2015

Am having trouble understanding how to print my results (I have 50 of them) , only 10 per line.

Im using an array that is 1-50. The first 25 I raise to the power of 2 and print it.

The next 25, I multiple by 3 and print it

Public class KDowling { 
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
double [] alpha = new double[50]; //declare an array 50 indexes
int num=1; // declare variable num
int counter=1;

[Code] .....

I need to get this result:

1 4 9 16 25 36 49 64 81 100
121 144 169 196 225 256 289 324 361 400
441 484 529 576 625 78 81 84 87 90
etc...

Right now they are each printing out on their own line.

Swing/AWT/SWT :: Putting Text From Txt File Straight Into JComboBox

Sep 23, 2014

I have two classes - One is Read.java and the other is Display.java

Read.java looks like this

public static void main(String[]args){
File file = new File("test.txt");
try{
FileReader fr = new FileReader(file);
BufferedReader br = new BufferedReader(fr);

[Code] ....

Display.java looks like this:

public class Display extends JFrame {
private JComboBox comboBox;
private JPanel contentPane;

/**
* Launch the application.
*/
public static void main(String[] args) {
//method call to access other class

[Code] ....

Instead of having it so it displays the id's to the console,is there a way I can set it straight up to the combo box?

Declare Array Of 50 Elements Of Type Double - Print Output 10 Elements Per Line

Feb 5, 2015

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class array
{
public static void main(String[] args)

[Code] ...

Is there a way to write this, where, alpha is one array.

Write a program that declares an array "alpha" of 50 elements of type "double". Initialize the array so that the first 25 elements are equal to the square of the index variable and the last 25 elements are equal to three times the index variable. Output the array so that 10 elements per line are printed.

If I have an array of 50 integers, can I break that to read in lines of 10?

Identify Duplicate Line And Print Them As Duplicate Found

Apr 6, 2014

I have a java file 'Arithmetic.java', in which i have 2 overridden method.Now i wanted to read this file and i need to print all the method signature lines,if i found same(overridden method)signature then i have to print "overridden method found". once i find the overridden method i have to suffix the method name as methodName_overridden1, methodName_overridden2 and so on...

package com.abcd.arithmetic;
public class AllArithmatic
{
public Integer add(int x,int y,int z)
{
return (x+y-z);
}
public Float substract(float x, float y)

[code]....

till now i am able to read the lines, able to read the method names as well. but while putting the entire method signatures into an string array and the suffixing part , i am not able to proceed. The condition i have put to find out oerridden method is nnot working.i am stucked in comparing the duplicate method

//Finds Method Name, Method Return Type
if(indexOfMethod >-1 && indexOfOpenBrace >-1){
int uniqueWordsInFile=0;
//Method signature Start
//System.out.println("method line="+line.trim());
List<String> methodList = new ArrayList<String>();
methodList.add(line.trim());

I can make my program print block letters out in a vertical format but I need them to come out in a horizontal format.

public class MISSISSIPPI {

Swing/AWT/SWT :: Construct A Vertical List Of JPanels

Feb 11, 2014

I am working on writing a desktop based email client using swing. First some specifics: I need to show emails in a (dynamically updatable) vertical list. Each item in this vertical list would represent an email showing: (a) the subject, (b) a photo of the sender that I have locally available & a couple of buttons. So, I plan to create a JPanel containing a JLabel to show the Subject, The photo inside a JLabel & JButtons. I have the layout of this panel done and is not a problem.

My problem is with stacking all these JPanels (each representing an email) and showing them on the UI as a list. I am not sure of any way to do this. Moreover, when a new email is received, it has to be displayed at the top of the list (not at the bottom).

Specifically, I need a good way of displaying a vertical list of JPanels & be able to add new JPanels at the top of the list.

Swing/AWT/SWT :: Positioning Slider Of Vertical Scrollbar Not Working

Apr 4, 2014

I have written a drum machine using Java. Into said drum machine I list all 47 available MIDI drums. The instrument list is placed into a JPanel, along with a gridArray of checkboxes. The JPanel is then in turn added to a scrollpane. I have listed the MIDI drums in order of 'ground-up'. For example, the bass drum is generally at the bottom of most drum kits, so it is at the bottom of my MIDI drums list. Next up would be the snare, followed by the cymbals, and then by all the specialty percussives. Since most beats are started from the 'ground-up', laying to foundation, so to speak, I want the scroll bar of the scrollpane which houses the JPanel, which in turn houses the instrument list and the beat checkboxes, to be positioned, upon opening, at the bottom of the scroll pane. Nothing I have tried works. It always positions the slider somewhere in the middle of the scroll track. Below is a listing of just the buildGUI portion of the code, all the MIDI functionality has been removed to keep the size of the post to this forum down.

import java.awt.*;
import javax.swing.*;
import java.util.*;

public class BeatBoxG
{
JFrame overallOuterFrame;

How To Make File Reader Object Move To Next Line If There Is No More Input On Line

Feb 18, 2015

How do I make the file reader object move to the next line if there is no more input on the line. Here is my text and output file as you can see that my text file column cuts off on the 2nd line after 70. I want to read that next line which is 100 into my labs variable however its reading it into my final exams variable. I'll also post the code but I didn't think it was necessary.

textfile:
100908095
1008070
10070

output:
Labs Projects Tests Final Exams
100908095
1008070100
70

[import java.util.Scanner;
import java.io.*;
public class MyGrades
{
public static void main (String[] args) throws IOException
{
int lab, project, test;
int finalExam;//Par and Player values

Swing/AWT/SWT :: Moving Image Left Or Right

Mar 11, 2014

I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.

public class MoveIt extends Applet implements ActionListener
{
private Image cup;
private Panel keypad;
public int top = 10;
public int left = 10;

[Code] ....

I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.

Drawing Shapes Bottom Right To Top Left

Mar 17, 2014

I am having issues with drawing shapes from bottom right to top left.

Issue:

- g.drawRect() will show like I am calling g.fillRect()
- other shapes will not even show the shape in that area

Needs:

- g.drawSHAPE needs to show and not be filled unless I have my fill checkbox selected

The Program:

- Create a JFrame with a draw panel and a component panel
- have a combobox with shapes that, when selected, will draw that shape in the draw panel
- have a button that, when clicked, will launch JColorChooser to change the color of the drawn shape (draw panel is set to black)
- have a checkbox that, when checked, fills the shape
- have mouse listeners to adjust X and Y and will instantly update the shapes size to where you drag/click/press/release

Code for my drawRect():

Java Code:

// if statement to check if mouse drag X is less than starting X
if(x2 <= x){
if(emptyORfill.isSelected()) // emptyORfill is my JCheckBox
g.fillRect(x2, y, x-x2, y2-y); // x-x2 is the same as Math.abs(x2-x)
else
g.drawRect(x2, y, x-x2, y2-y);

[Code] .....

This is just for my Rectangle. This will show a filled rectangle when both mouse drag X and Y are less then the starting X and Y. If I take this fully functional code and adapt it to drawRoundRect(), the round rectangle wont even show the shape when mouse drag X and Y are less than the starting X and Y but will be fine if one or the other is less than the starting X or Y. NOTE: This same exact code worked on my classmates laptop in her program, but in my program on her laptop it did not. She took out the "else" in the else if's and just made them if statements all the way down and it worked on her laptop in my program, but the same "fix" did not work on my pc.

My mouse listener just sets X and Y values in my Shape class that updates my shape methods. I have an item listener for my comboBox that sets default values when a new selection is made and enables/disables editable on my fill checkbox for certain shapes. My action listener looks for the button click and the checkBox click.

Setting Left And Right Node Values

May 6, 2014

I am getting errors when I try setting left and right values (which are String types) for my tree.I tried doing something like:

Node node = new Node("Is it human?", null, null);
node.getLeft().setNode("Is it Zelda?");//the first left Q
node.getRight().setNode("Is it Kirby?");//the first right Q

but that gives me a runtime error of "java.lang.NullPointerException" which points to the line 2. I also tried this:

Node node = new Node("Is it human?", null, null);
node.setLeft(setNode("Is it Zelda?"));//the first left Q
node.setRight(setNode("Is it Kirby?"));//the first right Q

but that gives me another error, pointing to the setNode for both lines 2 and 3,plus it wouldnt make sense since both setLeft and setRight takes in Node types, not String types.

Here is my Node class:

public class Node {
private Node leftPt, rightPt;//left and right pointers for Node
private String node, left, right;
public Node(String node, Node leftPt, Node rightPt){
this.node = node;
this.leftPt = leftPt;
this.rightPt = rightPt;

[code]....
