Question

Write a Java program that does the following:

1. Asks the user for the names of 3 cities, separated by spaces. It is assumed that a given city name won't have spaces in it. So assume you won't have a city name like "Santa Monica".

For example your program prints this: "Please input 3 city names separated by spaces in one line and press Enter."

The user then will type something like:

Glendale Pasadena Burbank

and press Enter.

2. Your program then prints the 3 city names in alphabetical order. For example:

Burbank

Glendale

Pasadena

The goal of this assignment is to get used to Strings in Java and how to compare those strings.

Explanation / Answer

Create a file named app.java and paste given code. Filename must be app.java

import java.util.Scanner;
public class app {
  
public static void main(String[] args)
{
Scanner scanner = new Scanner(System.in);

System.out.println("Enter the city names");
String line = scanner.nextLine();
String [] cities = line.split("\s");
String s1 = cities[0]; String s2 = cities[1]; String s3 = cities[2];
if(s1.compareTo(s2) < 0)
{
if( s1.compareTo(s3) >= 0 )
{
System.out.println(s3 + " "+ s1 + " "+ s2);
}
else if(s1.compareTo(s3) < 0 && s2.compareTo(s3) >= 0)
{
System.out.println(s1 + " "+ s3 + " "+ s2);   
}
else
{
System.out.println(s1 + " "+ s2 + " "+ s3);   
}
}
else if(s1.compareTo(s2) > 0)
{
if( s2.compareTo(s3) >= 0 )
{
System.out.println(s3 + " "+ s2 + " "+ s1);
}
else if(s2.compareTo(s3) < 0 && s1.compareTo(s3) >= 0)
{
System.out.println(s2 + " "+ s3 + " "+ s1);   
}
else
{
System.out.println(s2 + " "+ s1 + " "+ s3);   
}   
}
else
{
if( s1.compareTo(s3) >= 0 )
{
System.out.println(s3 + " "+ s1 + " "+ s2);
}
else
{
System.out.println( s1 + " "+ s2 + " " + s3);   
}
}   
}
  
}
