..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).
