I am new to java programming and using bluej for programming and i have tried this question what i have have given in title ... How to do the following question without using strings.
Write a java program to input a binary value and convert it into decimal and Vice Versa. Without using String. Please make it for blue j format.
I do not know how to convert a reversed array to decimal.
The output should be:
How many digits to convert?
(user will input) ex. 3
Please input digits:
(user will input 3 digits)
ex. 0
1
1
The binary digits are: 110 (<-reversed)
The decimal value is: 6
Here is my code:
package numbersystemconversion;
import java.util.Scanner;
public class BinarytoDecimal {
static {
int digit=0;
Scanner input = new Scanner(System.in);
[Code] ....
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();

I'm working on creating the Binary to Decimal program . hat is wrong with this part of my code. Why does it not take you into the loop.
import java.util.Scanner;
public class question5 {
public static void main(String[] args) {
System.out.println("Enter a Binary number. "); // collect
Scanner keyb = new Scanner(System.in); //

This problem is from Java . It asks me to convert a binary number in to decimal. How to program this in java? I am not able to find an effective algorithm to convert in to Java.
View Replies View RelatedThere'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..

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.
I am new to java and programming in general. I figured out how to convert an integer input to binary however I am having issues doing the opposite of converting a user input binary number to a decimal.
I need to do this with basic math (or string depending on how I represent the binary) and no functions.
I know how to convert binary to integer on paper but I am having a hard time working it out in java.
I am designing a program in-order convert Binary to Decimal values with added features:
Rejecting binary values longer than 32 bits
Prompting the user to make multiple entries after completing the binary to decimal conversion of their first entry. I was trying to code this in Nested For Loops, but I don't know if I've really done that.
Here is what i have so far.
public class BinaryToDecimal {
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
String binary;
int decimal=0b10, i, rem;
boolean isBinary = true;

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).
Here is my code and i want to convert number into 2 decimal but this code not give me result how to check my code.
import javax.swing.JOptionPane;
public class showtime{
public static void main(String[] args){
double total_mili=System.currentTimeMillis();
JOptionPane.showMessageDialog(null,total_mili, "Total milisecond",JOptionPane.INFORMATION_MESSAGE);
double seconds=total_mili/60;
double sec=(double)(seconds * 100) / 100.000;
JOptionPane.showMessageDialog(null,seconds, "Total Second",JOptionPane.INFORMATION_MESSAGE);
JOptionPane.showMessageDialog(null,sec, "Total Second",JOptionPane.ERROR_MESSAGE);
}
}
Add the following method to the BankAccount class: public String toString()Your method should return a string that contains the account's name and balance separated by a comma and space. For example, if an account object named benben has the name "Benson" and a balance of 17.25, the call of benben.toString() should return:
Benson, $17.25
There are some special cases you should handle. If the balance is negative, put the - sign before the dollar sign. Also, always display the cents as a two-digit number. For example, if the same object had a balance of -17.5, your method should return:
Benson, -$17.50
Here is my code:
public String toString() {
String result = name + ", ";
if (balance < 0) {
result += "-";
}
return result += "$" + Math.abs(balance);
}
My code only works in case there are full two numbers for the cents part, not for the case when there's only one number. So I wonder how I can add an extra zero when needed.I can get only the decimal part and add a zero if it's less than 10, but I don't know how I can extract just the decimal part from the number. (The balance is just a double and it doesn't have any separate field for dollars and cents).
The code is below and the problem I am having is the numbers after the decimal won't add together for the total I am teaching myself java through liang's 10th edition book and I took one of the sample programs further than what was shown. The one in the book only shows the tax amount I simply wanted to make it so that the purchase amount and the tax amount would add together
package javalearning;
import java.util.Scanner;
public class FindingTax {
public static void main(String[] args){
Scanner input = new Scanner(System.in);
System.out.print("Enter Purchase amount: ");

What code to use to display decimal numbers only. for example 125.50. the program will only display .50
View Replies View RelatedI'm trying to complete a code to convert decimal to octal. however i can't figure out how to print the output correctly. it should be.. Your integer number 160000 is 0470400 in octal. (160000 is the number you input). My code is...
Scanner input = new Scanner(System.in);
int value;
int a;
int b;
int c;
int d;
int e;
int f;
int g;
String result;

Lastly, my output prints everything correctly, but the input number always is 0.
Ex error: input= 160000
Your integer number 0 is 0470400 in octal.
it should be.. Your integer number 160000 is 0470400 in octal.
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

designing a program which allows you to buy stuff from the jframe with 10x items each with different pricing, so once you click the image button the cost of that is displayed in the textfield, ive been trying to set the jtextfield to a decimal point but have not been able to so far,

I am a beginner in Java and I am currently learning about JOption pane.Using Strings I am accepting an input from the user and by using the Interer.ParseInt(variable) option I am able to multiply this two strings using the code below.
String Length;
Length = JOptionPane.showInputDialog("Enter the Length");
String Breadth;
Breadth = JOptionPane.showInputDialog("Enter the Breadth");
System.out.println(" Area is " + (Integer.parseInt(Breadth) * Integer.parseInt(Length)));
System.exit(0);
How Do I make my code accept Decimal values. E.g. My Code should accept 10.02 as Length and 20.42 as Breadth and give the product a Decimal.
