Convert Hexadecimal To Decimal WITHOUT Using Integer ParseInt Method

Mar 12, 2014

So 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.

Decimal To Hexadecimal Number Conversion

Jul 16, 2014

Java programming, I decided to write a code today that would convert decimal numbers to hexadecimal numbers. Unfortunately, it does not compile. The error message is "cannot find symbol - variable A", and might be the same error for the other variables B,C,D,E,F.

Here is my code:

public class dec2hex
{
public static void main (String [] args)
{int nbr = 99;
char a = A;
char b = B;
char c = C;

[Code] ....

Converting From Decimal To Hexadecimal - How To Output Correctly

Feb 24, 2014

import java.util.Scanner;
public class FindHexString {
public static void main(String[] args) {
String hexString = ""; //output a hex string
int decNumber;//decimal number to be converted
int storeInput; //copy f input decimal number

[Code] ....

I am trying to figure out how to convert from decimal to hexadecimal without using the java library function. This is just a guess. I could be wrong.

Using Static Method To Convert A String To Integer Object - Compiler Error

Mar 1, 2014

I am using a static method to convert a string to an Integer object. Next using a instance method to convert Integer object to an int.

Compiler is giving me two "cannot find symbol" errors:

One pointing to the dot operator between "Integer.valueOf(s)"

The other pointing to the dot operator between "obj.intValue()"

I have latest JDK installed: jdk-7u51-windows-x64.exe

Looks like JCL installed correctly with rt.jar file located in "lib" directory under "Program Files"

Following is source code:

Java Code:

public class StringToInt
{
public static void main (String args [])
{
String s = "125";
Integer obj = Integer.valueOf(s);
int i = obj.intValue();
i += 10;
System.out.println(i);
}
} mh_sh_highlight_all('java');

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();

Convert String To Integer

May 21, 2014

I have to make a programm where the user gives you the bank sorting code and the account number and you give him the IBAN. That was so far no problem and I was done within minutes except of one thing that I simply can't figure out even though im trying since weeks. At some point I have to convert a string to integer. My research told me its with parseInt() and I dont get a syntax error when I compile my programm (using BlueJ). But when executing the programm stops and gives me some weird bug message. Here is code and bug message:

Java Code:

public class IBAN {
public IBAN(String Bankleitzahl, String Kontonummer) {
Bankleitzahl=Bankleitzahl.replace(" ",""); // Die Leerzeichen werden entfernt
int Anzahl=Bankleitzahl.length(); // Auf der Variabel Anzahl wird die Anzahl der Zeichen von der Bankleitzahl gespeichert

Program To Convert A Base 10 Integer To Any Base 2 - 16

May 5, 2013

I 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, 2015

I 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?
