Convert Binary To Decimal Such As Bin
Sep 20, 2014I 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();

Printing 2 Decimal Places - Printf Not Working?
Mar 22, 2014I need to print to 2 decimal places and I'm trying to use the printf method, but for some reason I keep getting an error. I've looked through my code, but unless I'm missing a small detail, it looks okay to me.

Manual Code For Converting Binary Octa / Hexa And Decimal
Aug 25, 2014There'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.*;

Modify Code That Converts Binary Code To Decimal Numbers
Aug 29, 2014The 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

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.

Count Number Of Digits After Decimal Point?
Jul 21, 2014Given a Numbers instance, whose fields are arrays of all the built-in Java numeric types (int, long, float, double, big-decimal, etc), write a method to sort all the numbers into a master list, and then print out the numbers where the number of digits past the decimal point is equal to the index of the number in the master list.
Is there a function in Java that will give me just the numbers after the decimal? I tried Decimalformat but couldn't get it to work. Here is what I have so far; however, I think I might be on the wrong track.
public class Numbers
{
public static void main(String[] args) {
Byte bNum = new Byte((byte) -50);
Integer iNum = new Integer(168);
Long lNum = new Long(100000L);
Short sNum = new Short((short) 10000);
Float fNum = new Float(12.19f);
Double dNum = new Double(23.123);
BigDecimal bd = new BigDecimal("3.14159265358979323846");

How To Format Methods To Display Number With 1-2 Decimal Places
May 8, 2014I am working with a program I wrote for class. I got it to compile and do what I want, But I was wondering how I can format my methods to to display a decimal with 1-2 decimal places. Would I create a method in my NumberAnalysis class to do it for me? Or would I declare an instance of the DecimalFormat class in my main method?
import java.util.Scanner; //Needed for Scanner Class
import java.io.*; //Need for File and IOException
import java.text.DecimalFormat;
public class Ex8_11 {
public static void main(String[] args) throws IOException{
{
DecimalFormat decformatter = new DecimalFormat("#0.00");
[Code] .....
This is my output:
Lowest Number: 1.09
Highest Number: 82.76
Total Number: 367.89000000000004
Total Average Number: 30.657500000000002
Think I just solved the answer to my own question, I did it by declaring double variables in my main method and called the methods and instantiated the variables into the methods... Is there a better way to do this?
package lesson4.skowronek;
import java.util.Scanner; //Needed for Scanner Class

Type Casting - Getting Number With Two Decimal Places As Output?
Jun 7, 2013"Type Casting" .... So the question is "How am I getting a number with two decimal places as output?"

How To Write JAVA Program That Read Whole Number And Tell Decimal Place
Oct 10, 2014Ex. 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?
Double RelativeFrequency Value Which Does Calculation / End Result Is Number With Lots Of Decimal Numbers
Nov 24, 2014for (int i = 0; i < letters.length; i++) {
double relativeFreq = (onesAverage()/letters[i]);
char a = characters.charAt(i);
double j = score[i];
System.out.printf();//ToDo
Above is my current code. Basically- There is a string called characters of length 26 (1 char for each letter in alphabet), a double relativeFrequency value which does a calculation and the end result is a number with lots of decimal numbers. The score array has set double values within the array.
What I want to do is create a print f statement where I print out each of the values I initialized above WITH specific amounts of spaces in between. So it should be in this order:
a (spaces) j (spaces) relativeFreq (newLine).
Between J and relativeFreq there should be 4 spaces, however if the value in relativeFreq is greater than 10 (it won't be greater than 100)- then there should be 3 spaces. Everytime I try to create a printf statement my code ends up crooked for some of the values.
for (int i = 0; i < letters.length; i++) {
double relativeFreq = (onesAverage()/letters[i]);
char a = characters.charAt(i);
double j = score[i];
System.out.printf("%c %.4s %.4s%n",a, j, relativeFreq);
Printing Out Value Of Each Number

double num3;

Printing First Number In Input
Mar 21, 2014Write a Java program ExtractNumber.java to read the data via the keyboard, character by character and print the first number (with or without a decimal point) contained in the input. For example, given the input data: Mary works for $43.75 per hour, the program should print 43.75 to the screen.
When i entered the sentence "The lady works for 8 hours at $10.00 per hour"
ERROR: My output was 810.00 instead of simply the first number 8

Printing Number Of Prime Numbers In A Range?
Feb 13, 2015The assignment is to make a program that prints the number of prime numbers in a range. This is what i have so far. The output is a list of 2s. I created the for loop to cycle through the range of 17-53 and nested a while loop within to test each incident of the for loop to check for divisors starting with 2 until the modulus result is 0 resulting in a false for being a prime number. Then the loop should increment to the next i value. The last part is an if statement that i had intended to add counters to the k variable that would keep track of the number of prime numbers.
boolean isPrime = true;
int j = 2;
int k = 1;
for (int i = 17; i <= 53; i++){
{
while (i % j == 0){
isPrime = false;

Getchar Equivalent In Java
Aug 1, 2014I was just wondering about the equivalent of c function getchar() in java? I am trying to assign letters to array elements through input stream. A simple code in java that matches this code:

for(i=0; i<10; i++){
array[i] = getchar();
}
for(i=0; i<10; I++){
putchar(array[i]);
}
How To Get Java Equivalent Of C++ Constant
Jun 10, 2014How to make sure that a variable passed to a method isn't altered by the method? I know in C++ you can do something like
void aMethod(const Object &item) {
........
}
I know that you can stop a variable from being reinitialized in java by doing this
void aMethod(final Object item) {
.........
}
However, that won't stop it from calling a setter on the item or changing something in it. Is there some other keyword out there that can do this? I just found that java DOES recognize the const keyword but that it really is useless.
So, any practical way that const can be further approximated in java beyond using final?
