Explanation / Answer
Convert.java
import java.util.Scanner;
public class Convert {
public static void main(String args[]){
//One Inch is 2.54cm . Its a constant and Its value wont change throughout the course of program
final double> //Scanner for I/O
Scanner sc = new Scanner(System.in);
//Enter Inches Value
System.out.println("Enter the Inches to convert it to Centimeter");
//Take Input
double inchesValue = sc.nextDouble();
//Convert by multiplying inches*cm
System.out.println(inchesValue +" inches are equivalent to "+inchesValue*oneInchToCm + " centimeters");
}
}

Problems run into: None
Program works correctly: We know Inch = 2.54 cm and can use a calculator to verify the output.
Data Values: a) final double is fixed for all executions of the program
b) inchesValue = inchesValue*oneInchToCm will change for each execution of the program
Algorithm: Straightforward multiplication by 2.4 will give inches to cm
Content and format of output: Since inchesValue is double thus i knew that centimetres value must be double too
Easy or Difficult: I think it was pretty straighforward program and thus i think it was easy.
DO THUMBS UP ^_^
