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.
java program to convert integer to Roman numbers and vice versa?
View Replies View RelatedI have a Set S=[1,2,3,4,5,10,12]
Now I want to convert this Set into a Range Statement which is of Form as follows...
Desired Range Statement Form is = 1..5/10/12.
Since 1 to 5 are contigious in my Set, they are represented as 1..5 and 10 and 12 are single non contigious elements they are given a single element with a union (/) Symbol.
Similarly, I want to convert the RangeStatement 1..5/10/12 to Set S=[1,2,3,4,5,10,12].
DO we have any efficient method to o this in Java? if I need to write my own method or is there any inbuilt method to do this.
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 have:
Java Code: String s = "111100100111011011000010110011101"; mh_sh_highlight_all('java');
I am trying to convert that to bits/bytes.
I need to make that into a series of bits with the same exact values..."1" = a 1 bit, and "0" = a 0 bit.
Remarkably, I haven't been able to find much on this sort of conversion - possibly I am just not searching with the right keywords? As typically, stackexchange or other parts of the web have the same question that I have, asked (and answered) by many others.
How do I go about doing this?
Furthermore, how would I go about saving this to a file - and are there already good "kinds" of files to save this into. If not, how do I go about making my "own" type of "file."
CONTEXT:
I've written a compression system. To keep things simple, I've been using a string to hold the 1s and 0s, so that debugging is simpler, and overall, everything is easier to write. Now, however, my algorithm is finished - and I'm moving on to create a GUI and a working system. This is the last step that I need for the non-GUI stuff (which I'm writing through javafx by the way - is this the right thing to use? I've been told that that is where people are moving towards. Away from swing).
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.

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

I do not know how to convert a reversed array to decimal.

(user will input) ex. 3
Please input digits:
(user will input 3 digits)
ex. 0

The binary digits are: 110 (<-reversed)
The decimal value is: 6

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 RelatedSo I have to write a java program that converts hexadecimals to decimals without using the whole "integer.parseInt(AB1, 16)" method. I tried looking up how to do this but every forum/site I went to used this same method.
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.
A GUI program that allows user to enter their name and the program will convert it in number using array.
For example if i input "EUNISE" the output should be 521149195
Because the letter equivalent of
a = 1
b = 2
c = 3
d = 4
e = 5
f = 6
g = 7
h = 8
i = 9
j = 10
k = 11
l = 12
m = 13
n= 14
o = 15
p = 16
q = 17
r= 18
s = 19
t = 20
u = 21
v = 22
w = 23
x = 24
y = 25
z = 26
Creating an array searcher wherein it all depends on the user input. On the first user input it would be the array to search from while the second input would be something to be searched for inside the loop?
View Replies View RelatedI 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’m trying to write a program in Java that will take the input of a temperature in Fahrenheit and convert it to Celsius and Kelvin. This is what I have so far but when I run the program on Eclipse it says the temp. in Celsius is infinity and the same for kelvin. Why is it not preforming the operation and spiting out the correct numbers?
import java.util.Scanner;
public class Temperature {
public static void main(String[] args) {
// This program converts temperatures from Fahrenheit to Celsius to Kelvin.
double temperature1;// operands
double temperature2;

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.

Scanner scan = new Scanner(System.in);
String binary;
int decimal=0b10, i, rem;
boolean isBinary = true;

I am writing a code in which a user inputs data as a string and that data must be verified as a valid number. A valid number is anything from 0-100. Then all valid numbers are converted into double numbers.
I am having trouble in how to write the validation part of the code.
Is it suppose to be an if, else statement? And if so how is it suppose to be validated?
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){

JOptionPane.showMessageDialog(null,sec, "Total Second",JOptionPane.ERROR_MESSAGE);
