public static void main(String[] args) {
System.out.println("Enter a Binary number. "); // collect
Scanner keyb = new Scanner(System.in); //

Convert Binary To Decimal Such As Bin

Sep 20, 2014

I am having an issue with my program. It is supposed to convert from a binary number to a decimal number such as bin 101 = dec 5. my first and foremost issue is that when I use System.out.println(parseBin("101")); it returns 5 as it should. However when I change 101 to 1013 it returns 13??? Why is this happening and why are my exceptions not catching the issue?

//import java.util.Scanner;
public class BinaryFormatException {
public static void main(String[] args) throws BinFormatException{
System.out.println(parseBin("1013"));
//Scanner input = new Scanner(System.in);
//System.out.println("Please enter a binary number using 1's and 0's: ");
//String binString = input.nextLine();

Manual Code For Converting Binary Octa / Hexa And Decimal

Aug 25, 2014

There's a main menu choosing binary,octa,hexa,and decimal if i choose decimal it will display decimal menu and then i will input the numbers of binary and then it automatically display the converting process for octa hexa and decimal. and if i choose octa . It display the octa menu and i will input the numbers in octa and then it automatically display the converting process for binary hexa and decimal.. and so on.. but in binary if i input 2 it will display invalid .. the same as octa hexa and decimal... in my code the only problem is the converting process. our instructor said no one will use a converter for our project. we will code it manually ..so for a moment .. this is my code..

import java.util.*;
import java.lang.*;
public class mainmenu {
public static void main (String[]args) {
Scanner in = new Scanner(System.in);
char B, O, H, D, Q, L, N , Y;

Modify Code That Converts Binary Code To Decimal Numbers

Aug 29, 2014

The code here I have works fine if I just want to ask the user to enter four digits: //java application that asks user to input binary numbers(1 or 0) and convert them to decimal numbers import java.util.Scanner; //program uses class scanner public class binarynumber{
 
//main method that executes the java application
public static void main(String args[]){
//declares variables
 
int digit;
int base=2;
int degree;
double decimal;
int binary_zero=0;
int binary_one=1;
//create scanner for object input

[code]....

The thing is, I want the java application to input more than four digits for the user and I want it to loop it manytimes f until the user ask it to stop.

Program Cannot See DECIMAL FORMAT

May 12, 2015

I am using NetBeans IDE 8.0.2 to program Java code. I am a beginner in Java.

Instead of getting two decimal places after the point, I am getting three despite using the code format for two ("##.##"). Actually, this happens even if I remove the format code between the quotes. It is as if the program cannot see the format code. Why this happens ?

Here is the relevant program code:

private void convertButtonActionPerformed(java.awt.event.Action Event evt) {
double inputNumber = 0;
// sets the decimal format

Calculator Program - Using Decimal And Operators

Oct 20, 2014

How do I get the code to use decimals? Also whenever you input 1, 2 or 3 as one of the operators, it always does that operator as well as the 4th operator at the end. So it always does subtraction. However when you use 4 as the only operator it works perfect.

Java Program - Distance Traveled (Formatting And Decimal Place)

I'm having trouble formatting my output and issues with the decimal places. Here's my code:

 public class lab3 {
public static void main(String[] args) {
String heading1 = "Hour", heading2 = "Distance Traveled";
int timeElapsed, hour, speed;

[Code] ....

And here's my output (Click on the image since it's pretty small):

Issue:
1) The Hours 2 and 3 aren't aligned to 1.
2) The 80 and 120 in Distance Traveled have 6 decimal places when it should not have decimals.

How To Write JAVA Program That Read Whole Number And Tell Decimal Place

Oct 10, 2014

Ex. If I type 5943, the program will say
mill = 5
hun = 9
ten = 4
uni = 3

get the picture I had to translate the decimal value names from a different language.

This is what I have tried...,

Java Code:

import java.util.Scanner;//Permite el uso de leer el teclado del usuario
public class DeterminarValorDecimal//Nombra el documento
{
public static void main(String [] args)//Podemos ver la clase
{

[Code].....

But what this does is I have to enter the single digits one by one. I want to be able to type the whole number. Is there a method that reads the length of the whole number and lets me classify each digit so I can do what I want to do?

GUI Java Program - Hex To Binary Converter

Mar 11, 2014

This code is for a GUI Java program that is supposed to convert back and fourth between two numbering systems. For example, binary to decimal or decimal to binary. I have created methods for some of the conversions however, I could successfully develop a method to convert from hex to binary. If you plan to run it to see what happens to the current method that I made please know that in the GUI the north end from left to right is as follows.

The textfield is for user entry of any type of data. The first combobox is for the user specifying to the program what type of data he or she entered. The second combobox is for the user to choose what he wants that data converted to. The button is to convert it. The south side has a textarea that gives out the results. Please note that only some of the conversions work so far. There are comments in the code to label which methods do what converisons. Need to find a method that will convert from hex to binary, what is wrong with the current method.

Program To Convert Temperature

Apr 24, 2014

Write a program that will provide temperature conversions between degrees Fahrenheit and degrees Celsius. Provide a method that will take an argument representing a temperature in Fahrenheit degrees and return the equivalent temperature in degrees Celsius. Also provide a method that will take an argument representing a temperature in degrees Celsius and return the equivalent temperature in degrees Fahrenheit. Conversion formulas are as follows: F = 9./5. * C + 32, C = 5./9. * ( F - 32 ), where F = Fahrenheit temperature and C = Celsius temperature. You must prompt for input using the Input class methods that are provided as a download for this unit.

I have two questions, 1st is why won't I get an output from my program when I run it? 2nd is how do I prompt for input using the Input class methods downloaded? The downloaded files are in .class form, and won't show any output when I run them.My code is:

import java.util.*;
public class temp
{
public static void main ( String [] args )
{
Scanner in = new Scanner(System.in);

Not Getting Decimal For Surely Decimal Answer?

Jan 1, 2015

I'm using eclipse. I'm going to get straight to the point and give all the info I can, if the values in the first code box are used, shouldn't these values be left after all in the second box is done:

remainder=23, arr[0]=100, div=23/10=2.3, whole=2, and decimal=3?

When I use this code, div comes out to be just (2.0).

Java Code:

int leng=10;
arr[0]=123; //int
arr[1]=100; //int mh_sh_highlight_all('java'); Java Code: if (arr[0]!=arr[1]){
int remainder=arr[0]-arr[1];
arr[0]=arr[0]-remainder;
double div=remainder/leng; //double div=Double.valueOf(remainder/leng);
int whole=(int) Math.floor(div);
int decimal=(int) ((div-whole)*leng); mh_sh_highlight_all('java');

I'm not sure were I'm going wrong in how div is being calculated, but I ultimately need div to be 2.3.

I've also used the second option commented out which still gives (2.0).
