Java program to Convert Binary To Decimal?

The decimal number is equal to the sum of powers of 2 of the binary number's '1' digits place . Here we add only those powers whose binary is one. For Example :-

Binary Number	1	1	1	0	0	0	0
Power of 2	26	25	24	23	22	21	20
Value	64	32	16	8	4	2	1

                       64  +   32   +   16   +    0   +   0   +   0   +   0   = 112

public class BinaryToDecimal {

public static void getDecimal(int num){

int binary = num;

int i = 0;

int decimal = 0;

while(num > 0){

int temp = num % 10;

decimal+=Math.pow(2, i++)*temp; 

num = num / 10;

}

System.out.println("DECIMAL OF "+binary+" : "+decimal);

}

public static void main(String[] args) {

BinaryToDecimal.getDecimal(11);

BinaryToDecimal.getDecimal(1110000);

}

}

Program Output :-

DECIMAL OF 11 : 3

DECIMAL OF 1110000 : 112
