C# Sharp Exercises: Creates two string-objects with different value

C# Sharp String: Exercise-39 with Solution

Write a C# Sharp program to create two string-objects with different values. When it calls the Copy method to assign the first value to the second string, the output indicates that the strings represent different object references although their values are now equal. On the other hand, when the first string is assigned to the second string, the two strings have identical values because they represent the same object reference.

Sample Solution:-

C# Sharp Code:

using System;

class Example39
{
   public static void Main() 
   {
      string s1 = "JAVA";
      string s2 = "Python";

      Console.WriteLine("s1 = '{0}'", s1);
      Console.WriteLine("s2 = '{0}'", s2);

      Console.WriteLine("\nAfter String.Copy...");
      s2 = String.Copy(s1);
      Console.WriteLine("s1 = '{0}'", s1);
      Console.WriteLine("s2 = '{0}'", s2);
      Console.WriteLine("ReferenceEquals: {0}", Object.ReferenceEquals(s1, s2));
      Console.WriteLine("Equals: {0}", Object.Equals(s1, s2));

      Console.WriteLine("\nAfter Assignment...");
      s2 = s1;
      Console.WriteLine("s1 = '{0}'", s1);
      Console.WriteLine("s2 = '{0}'", s2);
      Console.WriteLine("ReferenceEquals: {0}", Object.ReferenceEquals(s1, s2));
      Console.WriteLine("Equals: {0}", Object.Equals(s1, s2));
   }
}

Sample Output:

s1 = 'JAVA'                                                                                                   
s2 = 'Python'                                                                                                 
                                                                                                              
After String.Copy...                                                                                          
s1 = 'JAVA'                                                                                                   
s2 = 'JAVA'                                                                                                   
ReferenceEquals: False                                                                                        
Equals: True                                                                                                  
                                                                                                              
After Assignment...                                                                                           
s1 = 'JAVA'                                                                                                   
s2 = 'JAVA'                                                                                                   
ReferenceEquals: True                                                                                         
Equals: True
