Distance conversion

Hi Friend,

Try the following code:

import java.util.*;
public class ConvertMeter{
public void showKilometers(double meters){
double kilometers = meters * 0.001;
System.out.println(meters+" meters is "+kilometers+" kms");
}
public void showInches(double meters){
double inches = meters * 39.37;
System.out.println(meters+" meters is "+inches+" inches");
}
public void showFeet(double meters){
double feet = meters * 3.281;
System.out.println(meters+" meters is "+feet+" feet");
}
public void menu(){
System.out.print("Enter a distance in meters: ");
Scanner scan=new Scanner(System.in);
double m=scan.nextDouble();
boolean quit = false;

do{
System.out.println();
System.out.println("1. Convert to kilometers");
System.out.println("2. Convert to inches");
System.out.println("3. Convert to feet");
System.out.println("4. Quit the program");
System.out.println();
System.out.print("Enter your choice: ");
int menu = scan.nextInt();
switch(menu) {
case 1:
showKilometers(m);
break;
case 2:
showInches(m);
break;
case 3:
showFeet(m);
break;
case 4:
quit = true;
System.out.println("Bye!");
break;
default:
System.out.println("Invalid Entry!");
}
}

while (!quit);

}
public static void main(String[]args){
ConvertMeter convert=new ConvertMeter();
convert.menu();
}
}

Thanks
