For Loop To Convert Any Number Entered To Base 10 With Any Base Provided
Oct 9, 2014So i'm writing a for loop to convert any number entered to base 10 with any base provided as well. My code does not work because I need a way to reverse the code order, so the new number is printed correctly with the given base. My code so far:
public static void main (String[] args) {
Scanner kb = new Scanner (System.in);
System.out.print("Enter a number :: ");
int numOriginal = kb.nextInt();
System.out.print("Enter a base :: ");
int base = kb.nextInt();
[Code] .....
newBase has a problem with how it calculates the new number, looking for correct newBase code for conversion?
Program To Convert A Base 10 Integer To Any Base 2 - 16
May 5, 2013I am writing a program to convert a base 10 integer to any base 2-16. Here are the terms:"The method is to convert the decimal value the user selected into whatever base the user selected and print the converted value one place value at a time by using an index into an array of characters 0-9 amd A-F that is initialized to contain those characters.In the method you will find the largest place value (i.e. power of the base) that will divide into the decimal number.
Then you can set up a loop that will operate from that power down to and including the 0th power to determine how many times each place value goes into the decimal number. Using the loop counter, index into the character array to print the character that corresponds to the quotient number and then subtract the product of the place value and the quotient from the decimal number. With the power (loop index) decreased, repeat until you finish the 0th place value. Here's what I have so far:
import java.io.*;
import java.util.Scanner;
public class ConvertIt
{//start program
public static void main(String[] args)
{//start main
Scanner input = new Scanner(System.in);
System.out.println("Enter a positive integer from 0 to 10000.");
int number = input.nextInt();

Hexadecimal Java Base Converter
Apr 28, 2015I am writing a program that converts any base 10 number to bases 2-16. I have the code for everything up through hexadecimal conversion, for that requires the use of letters. I understand an array list may be of use however I do not understand how to use that in this code. Below is what I have so far
import java.util.*;
import java.io.*;
public class convertBase
{
public static void main(String[] args)
{
int base;
int number;
String newNum;
[code].....
I commented out the hexadecimal portions.How would I go about coding for letters?
Java App To Open A Console Base Program And Run A Command
Jan 13, 2015I am struggling getting my java app to open a console window on either MacOS or windows and run a command. On windows I can get the cmd.exe program to open, but it won't execute the command. On MacOS, I cannot get it to even open the terminal.
String run = "c:
s34bil.exe
elap5.exe" + in + rst + out; //in, rst, out are parameters for the relpa5.exe file.
try {
Runtime rt = Runtime.getRuntime();
rt.exec(new String[]{"cmd.exe","/c",run,"start"});
} catch (IOException ex) {
Logger.getLogger(issrsUI.class.getName()).log(Level.SEVERE, null, ex);

Servlets :: Getting Path Of The Base URL?
Feb 5, 2014I have a data.json in my J2EE web app.I need to load it either from local path when unit testing or from url when the server starts up.
so I've set it to get the local path by default and what I'm trying to do is that it is is running on a server, I'd like to change the path to a url.
Here is my code:
public String getUrlBase(HttpServletRequest request) {
URL requestUrl;
try {
requestUrl = new URL(request.getRequestURL().toString());
String portString = requestUrl.getPort() == -1 ? "" : ":" + requestUrl.getPort();
return requestUrl.getProtocol() + "://" + requestUrl.getHost() + portString + request.getContextPath() + "/";
} catch (MalformedURLException e) {
e.printStackTrace();
}
return null;
}
which works fine. The only issue is that I had to place this in the login page. Is there a way I can only set the path to the base url upon server start up?
Base Converting Program
Jan 24, 2015The idea behind this program is that the program prompts the user to input an initial base (2-36), which checks to ensure that it is a valid int, then asks for a number to convert (which is taken as a String), then it asks which desired base the user would like to convert said number to. I have a basic program that is not complete, but allows me to do a few conversions using convertTo. I believe that I am going to have abandon this method and try mathematically converting every number. This leads me to what I can and cannot do. I am unable to use the initialBase as a condition to know what kind of number i an converting. For instance, I don't know how to make program know that if "2" is the initialBase, that that means that the String is a binary number. THAT is what I'm having problems with.
Here is my initial program that has a few things that are copied and pasted from other bits of my code in my program:
XML Code: Url...
I have broken down what I (think I) need to do here: Check to see if the input base is 2, 8, 10, 16, or 32. Hint: Put the possible bases in an array, and check the input base against the array. Check to see if the input number is valid for the base. Hint: Create a String "0123456789ABC...V" and compare each input character with the first "base" characters of the String. Check to see if the output base is 2, 8, 10, 16, or 32. Hint: Use the same possible bases array you used in step 1 to verify the input base.Check to see if the input base is equal to the output base. If so, print the input number. Perform a conversion from the input base to base 10. Perform a conversion from base 10 to the output base. You do this in 2 steps because it's easier to check each conversion separately.Output the converted number.
Base Form For Add / Edit / Delete
Sep 7, 2014I have been developing what I intent to be a base class for several forms that will allow the user for adding / editing / deleteing records. These records could be customers, products, suppliers etc.
I have designed a basic form that has an add, edit and delete button. For the add button, I would want to clear all the values in all of the controls (textboxes, combox etc) in preperation for adding a new record.
My question is this. Is this something I should do in the base class OR should it be handled in the classes that will extend from the base class? Perhaps if the controls were datalinked to the data they will clear themselves (I haven't got that far yet so I dont know). I thought maybe I could write code in the base class that could loop through all of the controls and call this from the extended classes.

Program To Change Base Of Integer Decimal

Scientific Method - Compute Base Times 10 To Exponent
Feb 13, 2015This is what I need to do: Write a method called scientific that accepts two real numbers as parameters for a base and an exponent and computes the base times 10 to the exponent, as seen in scientific notation. For example, the call of scientific(6.23, 5.0) would return 623000.0 and the call of scientific(1.9, -2.0) would return 0.019.
This is the method I have written:
public double scientific(double num1, double num2); {
double base = num1;
double exp = num2;
double scientific = base * Math.pow(10, exp);
System.out.println(scientific);
return scientific;
}
These are the following error messages I received when trying to compile the code:
Line 4
missing method body, or declare abstract
missing method body, or declare abstract
public double scientific(double num1, double num2);
[Code] .....

Private Var Won't Save Value Of Public Getter Function From Base C
Sep 15, 2014I'm working on this program for a class to create objects of a commissioned employee and union employee. Everything seems to work ok, but when I run my final pay calculation, one of my getter functions will not pass the variable for the pay into a class specific variable called check. here is the code in this function.
public void finalPayCal_U() {
setweekPay();//calculates weeks pay under 40 hours, stored in getweekpay
check = getweekPay();
if(getHours() > 40){
check = check + (1.5 * (getHours() - 40) * getRateOfPay());
}
check =- Dues;
}
}
The issue lies in check = getweekPay();
I thought this was a legal move, but I can't get it to work. It doesn't come back with anything more than 0 any time I run it.
All of these functions are out of the base class, employee (this function itself lives in the derived union class)
public void setweekPay() {
if (hours <= 40) {
weekPay = hours * rateOfPay;
} else {
weekPay = 40 * rateOfPay;
}
}
When I run, this function works as it returns the value when i print it to test.
however, when I do the part that says check = getWeekPay() above, it doesn't change the check variable. The only thing I have on the check variable is the dues taken out of it at the end, so it ends up being a negative number.
I have a similar problem with the other derived class's check variable. Both classes have the same variable as private but one is check the other checkC.

Accessing Private Field Of Derived Object In Base Class?
Apr 1, 2013I have this piece of code I wrote a while ago to test something. The issue is accessing a private field of Base class in Base but of a Derived object.
Here is the code:
class Base

private int x;
public int getX()

The commented code does not work but casting d to Base does.
Forgot to mention that the compilation error is that x has private access in Base.
