 public class MultiplyTwoDecimalNumbers {
 
   public static void main(String[] args) {
       //variables of data type float are initialized 
       //to store the numbers
       float first = 1.7f;
       float second = 3.1f;
       System.out.println("Numbers to be multiplied are: " + first + "  " + second);
       // new integer product is initialized 
       // the value is kept equal to the product of both numbers
       float product = first * second;
       System.out.println("The product is: " + product);
    }
}

  • In this program, Floating-point variables first and second are initialized, and 1.7f and 3.1f are stored in them respectively.
  • It’s important to add f after the numbers to declare them as float otherwise they will be assigned type   double.
  • Another variable product is declared to store the product of the variables first and second using the operator.
  •  Finally println() function prints  product  on console screen.
