How To Make A Table That Prints Out Sin / Cos / Tan For Angles
Sep 30, 2014
I am stuck and having a problem trying to find what i believe is a simple fix but can't wrap my head around it. For class I needed to make a table that prints out Sin,Cos,Tan for angles in steps of 5 to 180. The problem is in my output with the first couple lines of the table. for angle 5.0 the Sin(.0872) Cos(.9962) and Tan (.0875) are being displayed on the angle line 10.0
public class TrigTable {
public static void main(String[] args) {
double angle = 0;
double sin =0;
double cos = 0;
double tan = 0;
System.out.println("Angle Sin Cos Tan"); // Table header for the values
[Code] ....
Here is the first couple lines of output:
Angle Sin Cos Tan
----- --- --- ---
0.0 0.0 1.0 0.0
5.0 0.0 1.0 0.0
10.0 0.0872 0.9962 0.0875
15.0 0.1736 0.9848 0.1763
20.0 0.2588 0.9659 0.2679
I am working on my java program it prints out a table of angles and the sin, cos, and tan. For extra credit he wanted us to use nest loops to create a space after every five lines. I have come real close to getting this to work but have a problem with the very end of the table. The table needs to stop at 180...
public static void printTable(double angle,double sin,double cos,double tan) { // Method to create a table for the values for (double j = 0; j <= 180;) { for (double i = 1; i <= 5; i++) {//loop to print five lines of code angle = Math.toRadians(j);
So I just processed this rectangular array and made myself a table. I want to put a label for each column to identify what the values are. My attempt at this failed miserably, because it looks horrible. Here is the necessary code.
If you are to compile this yourself, you would see the horrible output at the end. I would like to know how to properly align each label with its corresponding column.
The problem is that I populate the table with autoincrement primary key. I don't want it to be visible. I have been googling for hours to find no solution. It seems that sql/mysql provides no solution by selecting all table columns except one. So I wonder, how I could overcome this problem. Here is some of my code:
public void tableChanged(TableModelEvent e) { int row = e.getFirstRow(); int col = e.getColumn(); model = (MyTableModel) e.getSource(); String stulpPav = model.getColumnName(col); Object data = model.getValueAt(row, col);
[Code] .....
The ID is used in
stmt.addBatch("update finance.fin set " + stulpPav + " = " + duom + " where ID = " + studId + ";");
I tried to omit ID from my SELECT statement, I tried to put Date as a first element in data[iEil][0] but neither options were successful. Data hasn't been changed in database. NOW, everything works fine, except I don't want ID column to be visible in my table.
I need to process one component drag to the table. I misunderstand, how I can see to which Cell fall the component. I tried to use Event and Mouse event handlers in my custom Cell, but they do not work. I can copy the drag event to the table and table handles it, but how to get needed Cell I cant understand.
This is my codes in a button that if I click it . that information will send to Jtable but the problem is the jtable is in another frame so how can i connect this ?
DefaultTableModel model = (DefaultTableModel) new admin().tableBagtags.getModel(); if (txtName.getText().equals("")) { JOptionPane.showMessageDialog(null, "Please fill out all fields.", "Error!", JOptionPane.ERROR_MESSAGE);

I'm tyring to print the same output in console to a text file, but I can only get the last line of the console output in the text file, not sure what is wrong with my code:
while (in.hasNextLine()) { PrintWriter writer = new PrintWriter("output5.txt"); tempS = in.nextLine().toLowerCase(); System.out.println(wp.bestPages(tempS));
[code]....
What's causing only the last time to be printed in text file? Are there better ways to print console outputs into a text file than PrintWriter?
When I run this code, it is supposed to get one value from turnTimer(); and return it, just as a test. This works when I enter a valid pit. For example. If I were to input "A" when it's player one's turn, it will return 1, like it should. However, if I were to type "H" when it's player one's turn, it returns "Not a valid pit!"(like it should) but then it also returns 12. It shouldn't know that H is 12 because it's in a separate method. I'm confused as to why it's printing both values.
import java.util.*; public class Mancala { static Scanner input = new Scanner(System.in); public static int pit; public static void main(String[]args) { Mancala mancala = new Mancala(); int[] board = {0,3,3,3,3,3,3,0,3,3,3,3,3,3};
I've a ArrayList with dogs on, and I've a function that should allow me to delete a dog from the register and if the dog was found it prints "The dog was deleted" and if the dog doesn't exist in the arraylist it should print "the dog couldn't be found".
Everything works perfect until I shall delete a dog that is not first on the list. Then the program shows first "dog was not found" and on the row after "the dog was deleted" if the dog was second on the list. If it was third I will get 2 messages that the dog wasn't found and then that the dog was deleted. I've no clue why it prints both else and if!
public static void taBortHund(){ //Har tar vi bort hund fran listan //System.out.println(hundlista); System.out.print("Vilken hund vill du ta bort? "); String hunden = tangentbord.nextLine(); for (int taBort = 0; taBort<hundlista.size(); taBort++){

I was told to create a program that prints the time between 00:00 (0:00 a.m.) and 23:45 (11:45 p.m.) in the 24-hour clock and 12-hour clock format like this:
Write a method that prints characters using the following: public static void printChars(char ch1, char ch2, int numberPerLine). This method prints the characters between ch1 and ch2 with specific numbers per line. Characters are separated by exactly one space.Test your method with the following main method:
public static void main(String[] args) { printChars(‘A’,’z’,10); printChars(‘0’,’9’,5); }
So I'm trying to write a program that prints out the "most-repeated integer" in an Array.
For example: if an array contains {1,2,2,3} It would print out 2 as the result.This is what I got so far and according to my knowledge I think I'm correct but for some reason it doesn't work.. Please give me some inputs.
public class MostInt{ public MostInt (){ int[] array = {0}; for(int i = 0;i>array.length;i++){ if(i==i++){ System.out.println(i);
I made a heads or tails game but I'm getting a bug when the user says he doesn't want to play anymore. The statistics are printed as many times as the games played. If you want to test the code, write" cap" " pajura" and when the program says "Vrei sa mai joci?" that means "do you wanna play another one?" and you can answer with "da"(yes) or "nu"(nu) Here is the code:
import java.util.Scanner; public class cap_sau_pajura{ private static int user; private static int pc; private static String converted; static int usermove; private static int castiguri = 0; private static int pierderi = 0;
I don't want a tutorial that shows me how to do a util timer with a button, or that prints a message, or that does anything. I want the simplest possible snippet that makes the timer, lets me have it do something, and can be stopped. No bells and whistles, no strings, no sparkles and explosions. Just a timer.
The class Overloading below asks for two names and prints three different greetings. Your task is to write the class methods missing from the class declaration. Methods print the greetings as shown in the example print.
Hint:The names and parameter types of the needed methods can be checked from the main method because all methods are called there. This exercise also does not require you to copy the source code below to the return field.
The method declarations will suffice.
Example output Type in the first name: John Type in the second name: Doe
********** Hi! ********** Hi, John ********** Hi, John and Doe **********
import java.util.Scanner; public class Overloading { public static void main(String[] args) { String firstName, secondName;
package FracCalc; import java.util.Scanner; public class FracCalc { public static void main(String[] args) { Scanner scan = new Scanner(System.in);

I mean its not that important but i figure it will be better if I could print out the answer both in fraction format and decimal format. while my answer prints in fraction just fine how do i show it in decimal?
System.out.println("");
System.out.print("And "); System.out.print("answer in Decimal is: ");
import java.util.Scanner; public class smallestnumber { public static void main(String args[]) { Scanner input=new Scanner(System.in); int smallest =0; int number;

here is the output of my code:
Enter the number 88 Enter the number 8 Enter the number 6 Enter the number 55
I am trying to write a java program that prints out the number that is the mathematical constant e. As you input a number, the larger it gets , the closer it comes to 2.71828 . Here is my code:
//taylor series that prints out e^1=1+1/1!+1/2!+1/3!+..... import java.util.Scanner; public class taylor_1 { public static void main(String args[]) { Scanner input=new Scanner(System.in); int factorial =1;
