inputted from the keyboard one character at a time starting with a vowel (The vowels are a, e, i, o, and u) until a blank {spacebar} character is issued. You do not press enter after each character. Any other sequence should return an error message and a way of entering it correctly.
Having read in the list (or during the reading of the list) the program is to find the longest continuous occurrence of consonants, outputting the vowels between which this occurs and the length of this string of consonants.
{In the example above, the output would be 13ou}
Check for input errors and respond accordingly.
I have done most of it, the problem being that I don't know how to end the scan with a space so that I don't have to press enter. I have done the bit that finds the biggest amount of consonants in a row. (I'm writing in netbeans)
I am writing a short quiz program, and when the user inputs their answer they hit the enter key (the are int). But the last question on my quiz is asking the user to they want to repeat the quiz, but when I run the program, it won't allow me to input any information. I can briefly remember my lecturer saying something about entering in a code after each int the user inputs but I can't remember what it was.
Here is a snippet of my code:
//Question 3 do{ System.out.println("Question 3- What Hollywood actor did Mila Kunis have a baby with recently?"); System.out.println( question3 + ".Ashton Kutcher 2.Bradly Cooper 3.Leonardo Dicaperio h.Get a hint"); answer3 = stdIn.nextInt(); if(answer3 != question3)
import java.util.Scanner; class Sum { public static void main(String[] args) { int sum = 0; System.out.println("Please write a number, end with ESC button"); Scanner in = new Scanner(System.in);
I'm doing old projects . This loop will take any number, sum it and when you press the ESC button the loop will end and you will be shown the sum.
Java Code:
import java.util.Scanner; class Sum { public static void main(String[] args) { int sum = 0; System.out.println("Please write a number, end with ESC button"); Scanner in = new Scanner(System.in); int number = in.nextInt();
[Code] ....
Here is the error
Java Code:
Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The operator != is undefined for the argument type(s) int, null mh_sh_highlight_all('java');
So well, the int ain't boolean says itself. also null ain't that for string ?
The original project was to get the number using one dialog box, convert the string to int and run the loop, so when you pressed ESC there then the return would be null.
I have a program that uses a text file. The text file is in a folder called "map1". The text file itself is called "store1.txt". The program crashes when trying to read the text file, but has no problem with the folder. It also reads a png file called "1.png" and has no issue. When I change the name of the text file to "storeOne.txt", it works without problems. Why is this?
I have java program that I am debugging with NetBeans. In it I open a serial com port. It seems that if I exit the program the serial port is not closed so I cannot get the port the next time I start the program.
Is there a way I can detect that either the user clicked the "X" in the upper ight of the GUI or I clicked the "Stop Button" in NetBeans?
I am working on a management gui for a program. I have implemented the start server button. But now I need to get something working so that when I press stop server the javaw.exe process which is running the the other jar file is stopped and ended.
The gui is going to be using a javaw.exe as well and I don't want to end the entire thing.
I just want to end the javaw.exe process that is running the other jar file.
This is my code for starting it:
JButton btnNewButton_2 = new JButton("Start Server"); btnNewButton_2.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { Runtime rt = Runtime.getRuntime(); try { Process pr = rt.exec("java -jar DEDServer_release.jar");
[Code] ....
I just need to figure out what to do to stop it now.
In c++, I'm aware that you can use the ignore function to ignore numbers after space, but in string how do I ignore a number after space is found for instance, "109 33" how would I ignore 33?
I have an assessment for college, the part of my code that im struggling with is the part where the user enter their first name followed by a space and then their second name. I m using ---------------fullname = JOptionPane.showInputDialog("enter your firstname followed by a space then your second name " ); ------------- to capture this. the issue is if the user only enter 1 name I need to output an error. the issue is I cant find a way to tell if the user entered a second name. This is what I have so far:
public void makename() { // makes an inputbox to ask their name fullname = JOptionPane.showInputDialog("enter your firstname followed by a space then your second name " ); //separates the first and second name into 2 strings in order to make the username
[code]....
The problem is it accepts anything I type in without causing an error. What should I type in to stop this? ive tried anything but I cant find a way to tell if a surname has been entered or not.
I have been trying to space out output on a Java console window so that I have three columns with 6 rows of data from three different arrays. The code I have so far outputs the data with no problem however the spacing between the columns is uneven. My loop so far is made up as follows
for (int i = 0; i < printVotes.length; i++) { System.out.println(printNames[i] + " " + printVotes[i] + " " + printPrecent[i] + "%"); }
As you can see I have been manually adding the space between each element of the array but this means that the space between each element is different because the size of each element is different if work out a loop that works out an even amount of space between the elements and then print this along with the elements ....
I want to cut my string from space char but i am getting exception....
Java Code:
import java.util.Scanner; import java.util.StringTokenizer; public class NameSurname { public static void main(String args[]) { Scanner sc=new Scanner(System.in); String s0,s1=null,s2 = null,s3=null; s0=sc.next();
[Code] ....

my s0=Lionel andres Messi
And I want to break it as soon as i find space and save it in s1,s2 and s3
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 working on this space invaders game and I've been stuck trying to get the alien spaceships to move down in one group. The way we have to design the game is we have to implement at least these 3 classes. These classes are GameData,GamePanel, and Animator. GameData is all the action figures/models in the game. GamePanel draws all game action figures/ models on the screen. Animator updates periodicaly action figures positions,sizes, colors etc. I can get the aliens to move right but once they hit the end of the canvas I cannot figure out how to get them to move as a group down and then begin moving left. I tried to add alien objects to the GameFigures list and then have the update method in the Alien class be responsible for moving the alien ships, but I couldn't figure out how to make it work. So then I made an alienFigures list in the GameData class and I still cannot figure out what to do. Here is the GameData class
I started using Java a couple of days ago, If you haven't guessed I want to see if the user is typing a full name or not, but I'm actually not too concerned with any more complexity than I mentioned in the title. It's ok if an input like "GLba b" comes out positive.
I am setting text to textarea from textfield. It works perfectly. My challenge, however, is setting texts with spaces in-Between them. For example, what I observe is:Amount23 instead of: Amount 23. Is it possible to automatically create word space while setting texts?
1: 3D space. How do i define the space where i will make my world? Is there a certain point that i will define as 0,0,0 or is there some other way.
2: Camera positioning. When i have the 3D space, how to i make it so that the camera will show that what i want it to show. Lets say il define its lokatios 30,50,100 and direction is NW, then how to i make it so that is see the SW direction from the point 30,50,100?
