�� Write a Java program to develop an advance calculator with many
numbering systems. The program will support some services to allow the
user to convert from one system to another and make any arithmetic
operations with any system. Look at the following graph which demonstrates
the idea:

Number
String numb;
Void printInFormat( )

Binary
boolean check_B( )
int convertToDecimal( )
int SumTwoBinary(Binary
int SubTwoBinary(Binary
int MultiTwoBinary(Binary
int DivTwoBinary(Binary

Decimal
boolean check_D( )
int convertToBinary( )
int convertToOctal( )
int SumTwoDec(Decimal d)
int SubTwoDec(Decimal d)
int MultiTwoDec(Decimal d)
int DivTwoDec(Decimal d)

Octal
boolean check_Oc( )
int convertToDecimal( )
int SumTwoOctal(Octal c)
int SubTwoOctal(Octal c)
int MultiTwoOctal(Octal c)
int DivTwoOctal(Octal c)

��Your program should do the following:
1. Your program will deal only with integer part of any number.
2. Write classes to simulate the above graph with described fields and
methods for each class:
• Number class is a super class consisting of a number itself and method to
write a number in specific format. For example, if numb = "123", the output will
be printed as "The result is ***123".
• Binary, Decimal and Octal classes have some methods that describe
specific system. For example, the " convertToDecimal( ) " method in binary
class will convert the binary number to decimal and return it as an integer. The
methods of summation, subtraction, multiplication and division will take two
binary operators and return binary number. Each class will deal with its type.
• The methods "check" will check if your number is as expected that if your
object is binary, the input number must be in binary format that consists only from
0 or 1 and if it is not, the number will be returned to enter again. Each class will
deal with its type.

This code conversion from decimal-to-binary, but where I want to repair your mistakes

Please give us some more details of your problem.
( a ) Does your code compile?
( b ) Any errors or warnings? If there are then share them with us.
( c ) Is the program producing any output?
( d ) How is the actual output different to what you want / expect? Give details.

This code, super

import java.util.Scanner;
public class Number{

 private String numb;
 
 public Number(){
 	
 }
 public Number(String n){
 	numb=n;
 }
public void setNumber(String n){
 	
 	numb=n;
 }
 public String getNumber(){
 	return numb;
 }
 
 }
	

This method requires you to modify the
Is the conversion from a decimal to binary

I will test you to the originator of this method

This code, sub

import java.util.*;
public class Decimal extends Number{
		public Decimal(){
		
	}
	public Decimal(String n1){
		super(n1);
	}
		Binary d = new Binary();
	 public boolean check_D() { 

		boolean check = true;
		for(int i=0; i < super.getNumber().length(); i++){
			   if(super.getNumber().charAt(i) == '0' || super.getNumber().charAt(i) == '1'|| super.getNumber().charAt(i) == '2'|| super.getNumber().charAt(i) == '3'|| super.getNumber().charAt(i) == '4'|| super.getNumber().charAt(i) == '5'|| super.getNumber().charAt(i) == '6'|| super.getNumber().charAt(i) == '7'|| super.getNumber().charAt(i) == '8'|| super.getNumber().charAt(i) == '9'){
				   continue;
			   }
			   else {
				  check = false;
				  break;
			   }
		}
		return check;
	}
   public int convertToBinary(){
   		 Binary d = new Binary("11");
   		 d.check_B();
   		 d.convertToDecimal();
   		 int out;
   		 Scanner input = new Scanner(System.in);
		int decValue=0;

		int mod; 

	  decValue = (dec/2);
	  mod = (dec%2);
	  decValue = (mod/2);

	  } 
	  }while(!done);
	   	out=decValue;
	return decValue;
   } 
   public static void main(String args[]){
   	Decimal d = new Decimal("11");
   	d.check_D();
   	System.out.println(d.convertToBinary());
   }  
   
}

I want to be modified and transferred from the decimal-to-binary

This prevents code transferred from the decimal to Binary, which I want the amendment made by

import java.util.*;
public class dec{
	
	public static void main(String args[]){
   	System.out.println(convertToBinary("7"));
   }
   
	 public static boolean isDecimal(String input) { 

		boolean check = true;
		for(int i=0; i < input.length(); i++){
			   if(input.charAt(i) == '0' || input.charAt(i) == '1'|| input.charAt(i) == '2'|| input.charAt(i) == '3'|| input.charAt(i) == '4'|| input.charAt(i) == '5'|| input.charAt(i) == '6'|| input.charAt(i) == '7'|| input.charAt(i) == '8'|| input.charAt(i) == '9'){
				   continue;
			   }
			   else {
				  check = false;
				  break;
			   }
		}
		return check;
	}
	 public static int convertToBinary(String d){
		Scanner input = new Scanner(System.in);
		int decValue=0,mod=0;
		int i;
		i=Integer.parseInt(d);
		decValue=i/2;
		mod=decValue%2;
		return mod;
		
   }
   
}

In this code two ways, first to examine the number of decimal input is it or not, and not any error, and this is

 public static boolean isDecimal(String input) { 

		boolean check = true;
		for(int i=0; i < input.length(); i++){
			   if(input.charAt(i) == '0' || input.charAt(i) == '1'|| input.charAt(i) == '2'|| input.charAt(i) == '3'|| input.charAt(i) == '4'|| input.charAt(i) == '5'|| input.charAt(i) == '6'|| input.charAt(i) == '7'|| input.charAt(i) == '8'|| input.charAt(i) == '9'){
				   continue;
			   }
			   else {
				  check = false;
				  break;
			   }
		}
		return check;
	}

The next code finded error

The second method to enter the number through the String, and the conversion of decimal number system to Binary, I do not want to enter the number in the integer but I want to enter through the string, as I worked

public static int convertToBinary(String d){
		Scanner input = new Scanner(System.in);
		int decValue=0,mod=0;
		int i;
		i=Integer.parseInt(d);
		decValue=i/2;
		mod=decValue%2;
		return mod;
		
   }

Lol, why is this marked as "Advanced"? This is "Beginner" at most.

You're not converting anything with your algorithm. This is how you get the first binary digit:

int digit = number % 2;  <--- First digit

Now, do the same to the rest of the number until you process all of its digits.

int rest_of_the_number = number / 2;

I'll leave the rest for you to figure out.

Converting to binary is easy
init a String to ""
while the number to convert is > 0
prefix the String by number modulo 2
divide the number by 2

String convertToBin(int n) {
   String str = "";
   while(n > 0) {
	  str = (n % 2) + str;
	  n /= 2;
   }
   return str;
}

@lodetx hey dude, if you're gonna be hanging around in the help threads, help, don't bump. also there is nothing wrong with those posts, but make sure they aren't just trying to get code. if they are actually trying don't be a jerk. just some friendly advise

Merged again... you are playing with our patience and the time we spent answering all your duplicated posts
