Hint:
A simple way to convert a binary value to a decimal value.
- Multiply each binary digit by its corresponding base 2 placement value.
ANSWER:
we can convert binary to decimal in java using Integer.parseInt() and a custom method getDecimal().
Integer.parseInt(String s) takes 1 argument:
then Integer.ParseInt() will convert String of binary into integer and return it.
we will then convert this integer into decimal digit using a method int getDecimal(int binary).
code:
import java.util.*;
public class Main
{
//defining getDecimal method.
public static int getDecimal(int binary){
int decimal = 0;
int n = 0;
while(true){
if(binary == 0){
break;
} else {
int temp = binary%10;
decimal += temp*Math.pow(2, n);
binary = binary/10;
n++;
}
}
return decimal;
}
public static void main(String[] args) {
//taking 2 binary numbers as an input
Scanner sc= new Scanner(System.in);
System.out.println("Enter a 4-bit binary number");
String str1= sc.nextLine();
System.out.println("Enter another 4-bit binary number");
String str2= sc.nextLine();
//converting binary string number into binary integers.
int bin1=Integer.parseInt(str1);
int bin2=Integer.parseInt(str2);
// converting binary digits into decimal digits:
int dec1=getDecimal(bin1);
int dec2=getDecimal(bin2);
//printing out the decimal digits and their sum:
System.out.println("The first number is "+ dec1);
System.out.println("The second number is "+ dec2);
System.out.println("Added together is "+ (dec1+dec2));
}
}
