conversion from binary to decimal numbers as string

crist

..my problem is it can't read back...it is a decimal to binary conversion, the decimal to binary conversion is OK it will run.. but the binary to decimal its not working sample i input 1010 the result is 1111110010 supposed to be it is a 10...soory for my English

Code:

import java.util.Scanner;

class binaryLoop {
  public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.println("Please enter Integer");

int number = sc.nextInt();

String bin=bin1(number);


System.out.println("Binary number is: "+number+"    Decimal number: " +  bin);

  }

public static String bin1 (int num)
 {
int sum=1;
int temp=0;
String bin = "";
if (num==2) ;
while (num!=0)
 {
bin=(num%2)+ bin;
 num=num/2;

               }
return bin;
}
}

there is no condition for conversion from binary to decimal , you only wrote a function to convert to decimal to binary.
You will need to write another one to convert from binary to decimal where you will sum multiply of 2 power N (Position in string).
