Program to compare Strings in Java with or without case sensitivity

package com.hubberspot.example;

public class StringComparison {
 
   public static void main(String[] args) {
  
 String first = "StringComparison";
 String second = "StringComparison";
 String third = "stringcomparison";
 String fourth = "TesTcoMpaRisOn";
 String fifth = "STRINGCOMPARISON";
  
 System.out.println("first.equals(second) : "+first.equals(second));
 System.out.println("first.equals(third) : "+first.equals(third));
 System.out.println("first.equals(fourth) : "+first.equals(fourth));
 System.out.println("first.equals(fifth) : "+first.equals(fifth));
 System.out.println();
 System.out.println("first.equalsIgnoreCase(second) : "
                    +first.equalsIgnoreCase(second));
 System.out.println("first.equalsIgnoreCase(third) : "
                    +first.equalsIgnoreCase(third));
 System.out.println("first.equalsIgnoreCase(fourth) : "
                    +first.equalsIgnoreCase(fourth));
 System.out.println("first.equalsIgnoreCase(fifth) : "
                    +first.equalsIgnoreCase(fifth));
 System.out.println();
  
 System.out.println("second.equals(third) : "+second.equals(third));
 System.out.println("second.equals(fourth) : "+second.equals(fourth));
 System.out.println("second.equals(fifth) :    "+second.equals(fifth));  
 System.out.println();
 System.out.println("second.equalsIgnoreCase(third) : "
                    +second.equalsIgnoreCase(third));
 System.out.println("second.equalsIgnoreCase(fourth) : "
                    +second.equalsIgnoreCase(fourth));
 System.out.println("second.equalsIgnoreCase(fifth) : "
                    +second.equalsIgnoreCase(fifth));  
 System.out.println();
  
 System.out.println("third.equals(fourth) : "+third.equals(fourth));
 System.out.println("third.equals(fifth) : "+third.equals(fifth));
 
 System.out.println("third.equalsIgnoreCase(fourth) : "
                     +third.equalsIgnoreCase(fourth));
 System.out.println("third.equalsIgnoreCase(fifth) : "
                     +third.equalsIgnoreCase(fifth));
  
 System.out.println();
 System.out.println("fourth.equals(fifth) : "+fourth.equals(fifth));
 System.out.println();
 System.out.println("fourth.equalsIgnoreCase(fifth) : "
                     +fourth.equalsIgnoreCase(fifth));
 System.out.println();
   }

}
