Question

Show an example how to call a method with parameters with scanner input.

For example class distance.java

With variables

Then class distancetest.java with the method being called with the user entering input .

Can be numbers with double type.

Answer 1

Answer :

import java.io.*;

import java.util.Scanner;

public class Distance {

public static void main(String[] args) {

double number1, number2, result; // We will take an example of adition of two numbers to illustrate how Scanner class works

Scanner scanner = new Scanner(System.in);

System.out.println("Enter the numbers which you want to add:");

number1 = scanner.nextDouble(); // First number is scanned from the command line argument and stored in number1 variable

number2 = scanner.nextDouble(); // Second number is scanned from the command line argument and stored in number2 variable

DistanceTest test = new DistanceTest(); // An object of DistanceTest class is created

result = test.NumbersAddition(number1, number2); // Method of DistanceTest class is called using the object test and parameters are passed

  

System.out.println("The addition of the entered numbers is :");

System.out.println(result);

}

}

class DistanceTest {

DistanceTest() {

System.out.println("We are inside the constructor of DistanceTest class"); // This is just an illustration that object has been created of this class

}

double NumbersAddition(double num1, double num2) {

  

return num1 + num2;

  

}

}
