Take Multiple Inputs In Single Line Separated By Space
Dec 20, 2014
I want to take input in the following way:
Sample Input 1
3
45 3 14
Sample Input 2
5
12 34 5 56 7
The first line is the number of test cases and the second line is the corresponding values for the test cases. Java code for taking multiple inputs in the single line separated by a space.

I am working on my homework, and everything is fine. But I was wondering if I can fix one thing. basically it prompt from a user for a text file name and save the content as an array. some part of my code is here:
public class arraysort{
static BufferedReader kb = new BufferedReader(new InputStreamReader(System.in));
public static void main(String[] args) throws Exception {
System.out.print("Enter the first name of the file: ");
String input = kb.readLine();
int[] firstArray = readFile(input);
firstArray = bubbleSort(firstArray);

As you you may figure, it works if I put numbers separated by each lines. I was wondering if I can change it so that it works when I put numbers separated by space rather then each lines.

I'm writing a program that accepts three doubles from the user, and performs calculations on them. I want to be able to handle input mismatch exceptions on each individually (i.e., if the user enters a double for the first, then a letter for the second, I'd like to be able to keep the value entered for the first, and only require that the user try again with the second, then the third, etc.)... I tried putting each input instance into its own try/catch blocks, but it always goes back to #1 when an invalid input is entered. Right now, I have all three in one try/catch:
Java Code:
package com.itse2317;
import java.util.Scanner;
import java.util.InputMismatchException;
class Triangle
{
public static double side1 = 0.0, side2 = 0.0, side3 = 0.0;
[code]...

The question is Write a program that displays all the numbers from 100 to 1000, ten per line, that are divisible by 5 and 6. and separated by exactly a space.
My assignment requirements are to display this in Dialog Box / message box . I have written this code so far
import javax.swing.JOptionPane;
public class Exercise04_10 {
public static void main(String[] args) {
int count = 1;
for (int i = 100; i <= 1000; i++)
if (i % 5 == 0 && i % 6 == 0)
How to display the output in dialog box?

I need to generate a league table in Java based on results provided in the shape of user input. I have the 6 teams in an array. I need to ask the user how many wins, draws, losses each team has had.
for (String element : teams) {
System.out.println(
"Please enter the number of wins, draws and losses for " + element);
int[] wins = new int [6];
int[] draws = new int [6];
int[] losses = new int [6];
}
How do I pull 3 separate values from the user and then store each value in a separate element of each array? so if one team wins 3, draws 2 and loses 1 - I need to put 3 into the wins array, 2 into the draws array and 1 into the losses array? I then need to total all this in a table.

I have to read data from a text file and print it in a new text file. An example of one line is like this:
Johnson 85 98 75 89 82
I then have to take the average of all the numbers and assign a "grade" to the numbers for each line of the text file and make a new file so it looks like this for 10 lines:
Name 1 2 3 4 5 Average Grade
Johnson 85 98 75 89 82 85.80 B
My problem is extracting the data from the file so I can use it.

My application depends on eight default user roles (or account types). They can be renamed or disabled, but should not be deleted. I want to protect them from deletion using their uuid value from the db. How can I pass their uuids into a single variable so I can use that single variable in my conditional statement? If I should use an array, any example of how I might do this?

This particular program is supposed to prompt the user to input either an uppercase or lowercase Y to process a phone number, they are then prompted to enter the character representation of a phone number (like CALL HOME would be 225-5466), this repeats until the user enters something other than the letter Y. All of the words entered are to be stored into a single array. The program is then to convert these words in the array to actual phone numbers. Here is what I have so far.
import java.util.*;
public class Program1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
String begin;
int phoneNumber = number.convertNum();
[Code] ....
I realize that the second method doesn't have anything to return yet, I just wanted to put that in there while I was doing things that I actually know how to do ha. The convertNum() method is supposed to be the method with which the array of characters is converted to phone numbers.
I'm still trying to think my way through this. I would think it'd be easier to store the inputs from the user as individual letters rather than words for the sake of converting to phone numbers.
Also, we are only supposed to recognize the first 7 letters of each word that is entered, like the CALL HOME example, there are 8 letters but it's still a seven digit phone number, so I'm not sure how that would work.
Also, when printing the phone numbers after they've been converted, we're supposed to print the hyphen after the third number, I have no clue how that would be done from an array.

I have got a pretty good framework working for my hangman game so far, however I am quite stumped on how to find multiple instances of the same letter in a single string. I am using indexOf to find the instance of a character in a string, but it only returns the first instance. So if the words(s) contain(s) multiple instances it doesn't register the rest.
public static void main(String[] args) {
String word = "crazy horse";
String answer="";
String space=" ";
String dash="-";

I need to write out multiple BufferedImages to a single tiff file. Each image represents a seismic time slice which can be several megabytes in size. I have used the TIFFEncodeParam.setExtraImages method and saved all my BufferedImages to a vector but my since I create so many BIs I keep running out of memory. Is there a way to create a BI, write it out to a TIFF file, then discard the BI and create the next one?
