Thread: Why wont this method work?

I'm trying to create a method that takes a binary number as a string parameter and then prints out the decimal equivalent. For some reason my code isn't working but I feel like I am extremely close!

import java.util.Scanner;
 
public class Question1 {
 
public static void main(String[] args) {
 
Scanner input = new Scanner(System.in);
 
System.out.println(" Enter a binary number ");
 
String n= input.nextLine();
 
int hey = binaryToDecimal(n) ;
 
System.out.println(hey);
 
}
 
public static int binaryToDecimal(String num) {
 
char number ;
 
int n;
 
int x = 0;
 
int m=0;
 
for(int i=0;i<=num.length()-1;i++) { 
 
 
number=num.charAt(i);
 
n = Character.getNumericValue(number);
 
m = num.length()-1;
 
 
 
x +=n*Math.pow(2,m);
 
m--;
 
 
 
 
 
 
}
 
return x;
 
 
 
 
 
 
}
 
 
}

The code is quite difficult to follow. Perhaps you could edit your post to remove redundant empty lines and correct the indentation.

What is m supposed to represent in the binaryToDecimal() method? (In general it is a good idea to make variables as descriptive as possible) And what value should m have each time around the loop?
