Java Random Road Cross - Generate Random Number Between One To Ten
Dec 8, 2014The 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?");
}
}
}
Generate Random Number From 0 - 2
Jan 16, 2015How would I get java to generate a random number from 0-2? all I've been able to find on random numbers is math.random which gives you from .0 to .10. you can multiply this by 10 to get 1-10 or by 100 to get 1-100 but how to make it so java will simply let me tell it the rand of numbers I want or get a random number in a range that is not a multiple of 10. and I can't seem to find anything about it anywhere.
View Replies View RelatedRandom Generate Secret Number Into Array
Apr 1, 2014Trying to generate random integers, based off user-input for amount of integers, and then sort them into an array. The problem is that the second method needs to be int[] but I cannot figure out what to make the return result. The instructions say it needs to be an int[] in the UML diagram, so I know it's not supposed to be void.
Java Code:
public void generateNewSecret() {
Random rand = new Random();{
for (int i=0; i<numDigitsSet; i++) {
secretNumber[i]= rand.nextInt(10);
System.out.println("" + secretNumber[i]);

Generate Random Number Between Two Values That Can Be Negative Or Positive
Apr 30, 2015I am trying to make a method that generated a random number between two values that can be negative or positive.
So:

would give one of these: -0.2, -0.1, 0, 0.1, 0.2
JAVA Program That Will Generate A Random Phone Number
Mar 12, 2014Instruction: You work for a telemarketing company and you are required to write a JAVA program that will generate a random phone number. (talk about a real-world application)
-The phone number should consist of 10 digits
-The first 3 are the area code and should not begin with 0, 8 or 9
-The second 3 digits should not be greater than 742 and not less than 100.
-The last 4 digits can be any digits
-Print the number using the following format: "(xxx)-xxx-xxxx", this way it will look like a real phone number (use decimal formatting)

Generate Random Number Between 0 And 19 Which Represent Location In Array
Aug 2, 2014To simulate it, the program will generate a random number between 0 and 19, which represents the location in the array (i.e. index number). Then, the 3 numbers to the left and right of this location should be reset to the value 0. If there isn't 3 numbers to the left and right you may assume a lesser number depending on the boundaries of the array.
How to reset the numbers to 0 in the final array ?
Do While Loop To Generate 6 Random Numbers?
Mar 2, 2014I am currently taking a class in the field. My assignment is to generate 6 unique random numbers using a "Do While" expression. I might be mistaken but doesnt the inner loop execute first and then it works its way out? With this logic I believe my code should work but then again its not.
public class DoLottery {
public static void main (String args[]) {
int max= 10;
int random;
int random2;
int random3;
[code]...
I originally had output at the end but decided to comment it out to see if code would execute if I placed it every time the test was true.
How To Get Random Shapes To Generate Automatically
Aug 31, 2014I am trying to get random shapes to generate automatically. I was able to get just three shapes to generate but nothing random. When I added the random code now only the frame shows up and no shapes. I also keep getting an error with frame.setVisible(true). It says identifier expected. Here is what I have so far:
Main program:
import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class ShapeGen {
public static void main(String [] args) {
//Create window and set title
draw panel = new Draw();

Generate Random List Length?
Apr 16, 2015I have my code which will generate a random string using an ArrayList. However, I aso want to have it generate them in random lengths, not just using all the chars and numbers.

String[] CHARS = {"A","B","C","D","E","F","G",
"H","I","J","K","L","M","N",
"O","P","Q","R","S","T","U",
"V","W","X","Y","Z","1","2",
"3","4","5","6","7","8","9","0"};
List<String> pass = Arrays.asList(CHARS);
Collections.shuffle(pass);
for (String chars : pass) {
System.out.print(chars);
}

Generate Random Dice Rolls Using Get And Set Methods

Generate Random 100 Numbers From 0 To 9 In Array - Count How Many Integers There Are
Mar 7, 2014I'm trying to generate random 100 numbers, from 0 to 9, in an array using Math.random, but it only outputs 0s which is very confusing to me. Also, I need to be able to count how many different integers there are like 0s, 1s, 2s... 8s, 9s.
Here's my code, I only got as far as the array then got stumped on the counting part.
import java.util.Arrays;
public class countDigits {
public static void main(String[] args) {
//Create random generator and values
int numbers = (int)(Math.random() * 10);
int arrayCount = 1;
[Code] ....
and my results
0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0
Displaying Random Images In One Applet

Java Lotto - Randomly Generate Five-digit Number And Prompts User To Enter Five-digit Number
Sep 25, 20141. Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
- The user wins the first prize if the user input matches all five digits in the lottery number in exact order.
-The user wins the second prize if the user input matches any four digits in the lottery number in exact positions.
-The user wins the third prize if the user input matches any three digits in the lottery number in its exact position.
-The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position.
- The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.here is my code. I have tried replacing the && statements with || and it always returns either case 1 or case default.
import java.util.Scanner;
import java.util.Random;
class Hw5 {
static int getPrize(int g1, int g2, int g3, int g4, int g5,
int u1, int u2, int u3, int u4, int u5) {

We generate that number in separate transaction and that too in end of the business logic and then move to success page. But recently it got skipped due to time out error during updating .... the db usage is huge at some time and multi user doing operation which intern generate multiple number of this time.

View Replies View RelatedRandom Number Calculator
Feb 1, 2015the program basically has a random number generating, and I want to ask the user to try to guess the number, and keep guessing until the number is right. In addition to this, I need to put in extra conditions for too high or too low by 10. So for example, if they user guesses a number and its off by more than 10, then it prints that they guessed too high, and if its below 10 they guessed too low.
import java.util.*;
public class RandomNum
{
public static void main(String[] args)
{
Scanner scan = new Scanner(System.in);
[code].....
Modify the program to keep the user trying to guess the number till he/she gets it right, and stop once you guess the right number.Too high, high, too low, too low( If it's off by more than 10 = way too high, if its less than 10, way too low)
