Digital Unit Converter advanced Java programming source code
Digital Unit Converter in Java:
In Java, a Digital Unit Converter is a type of unit measurement calculator. It is used to convert the given digital unit to another unit. In this tutorial, you will learn how to develop a digital unit converter in the Java program.

import java.util.Scanner; public class Digital_Unit_Converter { public static void main(String[] args) { Scanner in = new Scanner(System.in); System.out.println("Enter the Unit which want to Convert from:"); String fromUnit = in.nextLine(); System.out.println("Enter the Unit which want to Convert to: "); String toUnit = in.nextLine(); UnitConverter from = new UnitConverter(fromUnit); UnitConverter to = new UnitConverter(toUnit); System.out.println("Enter the Value of Unit which want to Convert from:"); double val = in.nextDouble(); double meters = from.toMeters(val); double converted = to.fromMeters(meters); System.out.println(val + " " + fromUnit + " = " + converted + " " + toUnit); } }
