I have been set this task, which is supposed to make me code using string arrays. The idea is to generate random sentences.This is what i have been able to do so far :
package usingarraysagain;
public class sentences {
public static void main (String[] args){
String[] NOUNS = { "lizards",
"Nikola Tesla",

I've been trying to find the easiest way to write to generate a number which is between intervals of a arbitrary min and a max value.I've been searching for this but I don't find this particular thing.I've found that this combination works:
Java Code: int guess = rand.nextInt(max - (min - 1)) + min; mh_sh_highlight_all('java');
But I wonder, is this really the easiest way of writing it?
I am very new to programming. This is for a college assignment. It says in the brief of the assignment that we will need to convert Math.random to output a random number between 1-1000. How can I do this?
View Replies View RelatedI am working on a bingo project and created random numbers between 1 and 75 to generate. I have it set up that it shows the number in a text box and changes the color on the board if the number is called. When I test the program, some numbers are highlighted in addition to the number called. I believe this is because extra numbers are being chosen, but not being noted in the text box. Below is my code for the unique random numbers.
int CallNo;
String CallerTxt = new String();
public void CallNum() {
Random RandCall = new Random();
//Generate Caller Random Number
CallNo = RandCall.nextInt(75)+1;

For part of my program, I am trying to ask the user for input on generating a number of random characters. I have already done this with integers and doubles, how would I do this for characters using ASCII values? Would I use the same format as I did for generating integers (Shown in code)?
import java.util.Random;
import java.util.Scanner;
public class NewNumberCharacter {
public static void main(String[] args) {
// Create a Scanner
Scanner input = new Scanner(System.in);

I don't want to use an array. I do not know of a function built into Java to allow me to do this.
View Replies View RelatedI'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
Write a program to reverse sentences (demarked by a period) in a paragraph (demarked by an empty line input from the console) using any list of your choice.13. Create a vector that stores N numbers.
i need to reverse sentences in a paragraph.the sentences end with a period and the paragraph ends with a newline.
i tried to construct Vector<String> and Vector<Vector> reading input from scanner, but that didn't work because scanner skips newlines.
what should i do?
The program I'm supposed to create generates a random number between one to ten. Then the program is to ask me if I wish to cross the road. If you choose to cross, the outcomes for 0-2 are "You crossed safely." For 3-5, 75% of the time it should say "RIP you got run over", and 35% of the time it should say "You crossed the street." For 6-8, 60% of the time it should say you made it.", and 40% of the time it should say "You died". For 9-10, it should say "RIP".
So far I have gotten the random number generation part working. I have up to here:
import java.util.Random;
public class test4 {
public static void main(String[] args) {
Random random = new Random();
for(int i =0; i < 1; i++){
int num = random.nextInt(10) + 1;
System.out.println("The number of cars on the street are: " + num + "Do you wish to cross the road?");
}
}
}
My random integer always seems to be zero.. I am at the ends of my wit.

Is it a good idea to use the date and time with the first or last few values of the session ID. Or should I just use the complete session ID value for my "unique id"?

I have a problem in generating reports using java code. I created a report using iReport 5.5.0 with MySql Database connection. In iReports, it shows the correct output while previewing it. Then i copied my .jrxml file and pasted it into my netbeans project folder(..sample/web/WEB-INF/sample.jrxml) and then i added the required jar files in my project's library folder. i am generating the report in netbeans using jsp and servlet. THE REPORT IS GENERATING AND SAVED SUCCESSFULLY IN MY DESKTOP. BUT IT DOESN'T GENERATE THE REPORT FOR FIRST RESULT. For Example.., if i generating report based on a particular date. After executing the query, it returns 4 results. So it has to create the reports in 4 pages. But it generates the report for last 3 pages only. It doesn't generate the report for first page. I have attached my .jrxml file servlet file for your reference.

And here is the output I get :
Why do I get the output after year 2? I assume it has something to do with the remainder.
I also have to format this output with the decimal point, etc.. which I think I will be ok with after I get through this part.

After generating a. JAR with Netbeans Java, when I play I see the colors of the components, the design and formatting is lost and the form gets a very basic formatting, for example, if I set a button with the color [0, 40.255] and build the. JAR after this, when I run the. JAR this button turns gray, and it happens with all the layout of the form.

I am trying to generate a double number from the range [-1,2]
so what i did is this
xs[i]= Math.random() *(2-(-1))+(-1);
I did that as a loop to generate multiple numbers and i got this result:
initial x values 2.17 2.66 3.04 2.81 1.83 2.66 3.67 2.81 1.04 3.1 3 1.23 1.44 3.5 3.84 3.03 1.7 2.79 4 1.43
see some numbers are out of range! and i don't know why aren't there any minus numbers...
I am trying to iterate through all combinations of characters given a length n with the added notion that all characters are numerical (0-9).e.g I have been given n = 5. The I want to iterate through all combinations starting with "00000" and ending with "99999". My first instinct was to just have a for loop like the following:
for(int i= 0; i<99999; i++){
// extra code here
}
but obviously this does not a account for combinations such as "00010".

I'm trying to generate a multicoloured brick wall as part of an assignment using BlueJ.
According to the instructions we've been given, once the wall is set up and we invoke the draw() method, if we invoke the toggleMultiColoured method the bricks will go from being all read to a mix of 6 different colours...
...When I invoke the toggleMultiColoured method, however, the wall I generate is still red.
Here's the source code for the BrickWall class I wrote:
Java Code:
public class BrickWall

private int bHeight;
private int numRows;
private int rowLength;

I'm stuck with a problem. The code below generates a coloured image.
//Setting the size of the graphics window
final int WINDOW_DIMENSION = 200;
final int SIZE_FACTOR = 3;

//Constructing the arrays
char[][] firstArray = new char[WINDOW_DIMENSION][WINDOW_DIMENSION];
char[] secondArray = scan.toCharArray();
[Code] ...
What I would like to do is generate a picture which is mostly white but the colour boundaries of the original picture are in black. I tried using the code below but it doesn't produce what I wanted.
for (int a = 1; a < WINDOW_DIMENSION; a++) {
for (int b = 1; b < WINDOW_DIMENSION; b++) {
generate.setColor(0,0,0);
if(firstArray[a][b]!=firstArray[a-1][b] || firstArray[a][b]!=firstArray[a][b-1])
generate.setColor(255,255,255);
generate.plot(a,b);
}

Am facing a very strange issue. While trying to compile a very simple Hello World java program, the compilation completes successfully without any error or warning, but it does not generate the class file.
It happens when I compile with a particular jar file, otherwise compiling only the program (or with any other jar) does generate the class file. I am using java 1.7.0_45.
Well I want to generate a license key for my software product. I'm aware of Google's Guava Libraries for generating alpha numeric license keys. But I'm thinking it to do in a different way without using any such libraries or specifically guava libraries. Till now this is my plan that,
1. Get a MAC ID / IP Address of the system in which the application will be installed and ready for it's first use.
2. Store that MAC ID in a UNCOMMON File format in client's PC only.
3. And what should be the next step.?
