In this article, we are going to see how we can convert binary to decimal. We also write java code to convert binary to decimal.

Binary to Decimal conversion:-

Steps:-

• Take a variable to hold the decimal result.
• Take a variable power and initialize it with 0.
• Create a loop to Iterate binary number from right to left.
• Now calculate the value number *(2^power).
• add the value into the result variable.
• increase power by 1.
• End of loop.
• result variable will be hold the result value of binary.

Java code to convert binary to decimal:-

package gangforcode;
import java.util.*;
public class binaryToDecimal {
	public static void binToDec(String s) {
		int m=0;
		int k=1;
		for(int i=s.length()-1;i>=0;i--) {
			m+= (s.charAt(i)-'0')*k;
			k=k*2;
			
		}
		System.out.println(m);
			}

	public static void main(String[] args) {
		Scanner sc=new Scanner(System.in);
		System.out.println("Enter the binary string");
		String s=sc.nextLine();
		binToDec(s);
		
	}

}

Output:-

The same logic can be used to convert binary to decimal in other programing languages like C, C++, Python, etc.
