Ruby program to implement single inheritance

Last Updated : December 15, 2025

Problem Solution

In this program, we will create a superclass with constructor and method then we will inherit superclass into the subclass.

Program/Source Code

The source code to implement single inheritance is given below. The given program is compiled and executed successfully.

# Ruby program to implement 
# single inheritance.

# Super class
class SuperClass
	def initialize
		puts "SuperClass constructor";
	end

	def SayHello
		puts "Say hello from SuperClass";
	end
end

class SubClass < SuperClass
	
	def initialize
	    puts "SubClass constructor";
	end
end

subObj = SubClass.new;
subObj.SayHello;

Output

SubClass constructor
Say hello from SuperClass

Explanation

In the above program, we created two classes SuperClass, SubClass. And, we inherited the SuperClass into SubClass using the "<" operator. After that, we created the object of SubClass and called the SayHello() from the SubClass object and printed the appropriate message.
