16bit binary to decimal problem

[G. Graz]

I am trying to convert a string binary value to it's decimal value. the code I have below keeps on generating a zero (0) every time I run the application? I can go through my logic on paper and get the correct value, but I am at the end of my rope on why my code is not generating the correct result. Any suggestions would be of great help! Thank you in advance !!!

Here is my code:

private int BTD(int n, String bin)
{
int result = 0;

for (int i=0; i<bin.length(); i++)
{
result = (result * 2) + (bin.charAt(i)-'0');
}
return result;
}

Greg,

In the future, please post your code using the CODE UBB tags to make it more readable.

Not sure why you keep getting 0 as the result. I ran your code as is and get the expected results. How are you calling the code and checking the result?

[Jesper de Jong]

How exactly are you calling your method and how are you dealing with the result returned from the method? Note that the argument 'n' is never used in the method, so you could just as well remove it.

int value = BTD(0, "100110100111");
System.out.println(value);

Integer.parseInt("100110100111", 2) should work.

Thank you for all the help! I will make sure that future posts are done in the UBB format. The program connects to a user IO class which takes user binary input as a string and should convert it over to a decimal number. My teacher did not give us access to the .Java file for IO though. As long as my logic is correct , I think I will be ok because I know that my end of the application is correct. Thank you again for all the help!!
