Formatting Output in Java

Proper formatting of output is essential. There are times when the details presented are not formatted.

The code snippet below displays details in a formatted manner that is a better presentation.

import java.util.*;

public class StringFormatter {

   public static void main(String args[])
   {
      StringFormatter stringFormatter = new StringFormatter();
      stringFormatter.proceed();
   }

   final String stringSentence = "Hi there, is it true that you are coming home today?";
   
   private void proceed()
   {
      //Creating a Scanner with the string stringSentence
      Scanner scanner = new Scanner(stringSentence);

      //Scanning the string 
      while (scanner.hasNext()) {
         //Formatting the string. The first string will have 10 character spacing, this can be adjusted as needed. 
         //The option -10, 10 will add spaces leading and trailing respectively.
         System.out.println(String.format("%-10s: %s" , scanner.next().toString(), scanner.hasNextBoolean() ));
      }

      //Closing the Scanner
      scanner.close();
   }
}
