We make a class with two methods one for input and other for conversion and access this by object of this class. We first take the input as Binary from user. We define a method as convert() to convert the user’s input to Decimal.
Here is the source code of the Java Program to Convert the Given Binary Number into its Equivalent Decimal. The Java program is successfully compiled and run on a Windows system. The program output is also shown below.
System.out.println("Binary to Decimal");
scan = new Scanner(System.in);
System.out.println("\nEnter the number :");
num = Integer.parseInt(scan.nextLine(), 2);
String decimal = Integer.toString(num);
System.out.println("Decimal Value is : " + decimal);
public static void main(String args)
Binary_Decimal obj = new Binary_Decimal();
$ javac MainClass.java $ java MainClass Binary to Decimal Enter the number : 1010 Decimal Value is : 10
