I am trying to raise a real number to a negative value e.g x-y(x raised to power -y) which can also be written like 1/xk . I am trying to run th program each time bt it doesnt give me the desired result.
Here is the code
public class RaiseRealPower {
public void run(){
double value =readInt("Enter value ");
double power =readInt("Enter power ");
System.out.println("Answer is " +raiseIntToPower(value,power));

I am 4 weeks into my Intro to Java course and I am having a bit of trouble with my code. I need to make a program that will take a user inputted number, space the numbers out, then add them to a total sum. What I am having a hard time with is when I enter a negative number. I can't figure out what I need to do to have my program ignore the "-" in the string.
import java.util.*;

public static void main(String[] args) {
int number, digit, sum=0;
char digitPos;

I am not sure what is happening with my code, but it is giving me a negative number. I am trying to write a program that calculates the product of the odd integers between 1 and 25. I messed with the program and as soon as you enter a number over 22, the end result is a negative number.
int total = 1;
for (int i = 1; i <= 25; i += 2){
total *= i;
}
System.out.println("Product:" + total);
Ask the user to enter a sequence of at most 20 nonnegative integers. Your program should have a loop that reads the integers into an array and stops when a negative is entered (the negative number should not be stored). Invoke the average method to find the average of the integers in the array (send the array as the parameter).
how can I remove the negative number from the array and calculate the average of the posive elements without the negative ones? This is my code so far...
import java.util.Scanner;
import javax.swing.JApplet;
public class Parameters
{
//-------------------------------------
//Calls the average and minimum methods
//with different numbers of parameters

i am writing a program that would be used for ticket sales and their are 100 tickets and a person can only buy 4 at a time. i need my program to not go negative at the end and also i need to stop the user from entering a negative number.
import java.util.Scanner;
public class ticketmaster {
public static void main(String[] args) {
// Variable decoration uses strings , doubles and final doubles.
Scanner in = new Scanner(System.in);

I am trying to make a method that generated a random number between two values that can be negative or positive.
So:
rand(-0.2, 0.2);
would give one of these: -0.2, -0.1, 0, 0.1, 0.2
Basically i have a question ask me to write a program that read integer from keyboard until a negative number is entered, and then print out the max and min out of the number i have entered.
This is what i have done already which works, but i need to ignore the negative number when print out max and min...which i dont know how to do so. when i compile this program now it will always give me the negative number i enter at the end as minimum. which i need to ignore
Also if negative number is entered at once the program should print a error message say max and min are undefined.
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int large = Integer.MIN_VALUE;
int small = Integer.MAX_VALUE;
while(true) {
System.out.print("Enter a integer: ");
int n = in.nextInt();

I do now have the problem where i have to insert the numbers 1 to 100 individually in order to allow the program to accept a grade as high as 100%.
Also as soon as i type in a negative number the system crashes and shows me a error as attached.
/*

Ok so I have my program working for the most part. In this program I am supposed to take input from the user until they enter a negative number and that works, the problem is that it doesn't work if I enter a negative number on the first prompt. For example if I enter a 100 it would prompt me again and if I enter a negative number it would quit and give me the average, but if I enter a negative number the first time I am prompted the program just gives me an error. How do I fix that?
import java.util.List;
import java.util.ArrayList;
import java.util.Scanner;
public class Application {
public static void main(String [] args){
Scanner input = new Scanner(System.in);
List<Integer> grades;

In my cs class, we have to write a program that throws an exception if the user enters a negative number, the program should prompt the user to enter only positive numbers and then let them retype the number. But everytime I throw an exception, my program gets suspended.
What am I doing wrong, or is there no way to continue a program if an exception is thrown? Does the program automatically get suspended when an exception is thrown?
try{
do
{
N = kb.nextDouble();
if(N<0) {
throw new NegativeArraySizeException();
}
else
j++;
}
while(j==0);
fill.size(N);
}
catch(NegativeArraySizeException e) {
System.out.println("The number you entered must be positive. Please try again.");
}

View Replies View RelatedI am trying to understand the effect of calling real business logic from the test class. If I have a test class that call the service method which make update to DB. Is DB really changes through test class?
e.g.
Java Code: @Test
public void testUpdate() {
MyDto myDto = new MyDto(paramters to create new myDto object); //creating new dto object
myService.updateMyData(myDto); //passing new dto object for update (DB record really changed??)
MyDto testDto = myRepo.find(myDto.getKey()); //get record for the corresponding key
assert testDto.getSomeProp() == myDto.getSomeProp(); //what testDto.getSomeProp() return? new value send on myDto or old value from DB?

I want to work on a project related to MMO real-time strategy social game as a college project but i dont have enough knowledge on it starting from 3d object coding to server.
Also i would like to know what are things to be cosidered as its an online game whether the camera angel affect what are problems that might occur and how to outrun it. How to split the server so that in one server depending upon the geo-location some number of users will be connected and will be splitted in different servers depending on the location
I want the actions to be cloud based but the actions of the characters will be coded within the game and in every server maximum of 100 users can connect.

My intention is to see the real reference values (memory locations) of 2 StringBuilder objects as below:
StringBuilder sb2 = new StringBuilder("123");
StringBuilder sb3 = sb2;
System.out.println(sb2);
System.out.println(sb3);
I was expecting a printout like
@S234853
@S984724
But all I got was 123 printed twice. How can i print out the reference values instead of what is inside the StringBuilder object ?
I wanted to know some hints on where to begin if I wanted to create a program which compares an audio file with real time captured audio. I found this website "[URL]...", but I think this would not do the job, so what are the basics of audio in java and how to compare audio files and see if they are compatible.

I have tried with other geoIP service and weather forecast too. I get the same error.
Consider the url-pattern:
<url-pattern> /Beer/* </url-pattern>
The web app structure is: -
webapps

-->WEB-INF
--> {{Beer}} This can be real or virtual.
My book says that /Beer/* can be a real or a virtual directory. What is the difference between the two and how do I create a virtual directory in tomcat ?

How do you replace negative zero value with a zero value when Printing results:
I want to remove the minus sign in -0.0000 and instead have 0.0000.
I am Printing coordinates and I do not want to have negative zero.
the coordinates are defined as double.
System.out.format(java.util.Locale.US," %.4f %.4f %.4f %.4f%n"xCur ,yCur,xNext,yNext);
0.0000 1.0000 -0.0000 0.0000
I need understanding why
1111 1101 = -3
For some reason, I'm getting the correct result, but my negative sign is having issues. For example, if I do 1/4 - (-2/4), I get (-3/4).

How can I get same value as positive values?
Or How can I store positive value e.g. 131 as byte array element.
Please not my requirement is array must be ByteArray only
