Ruby program to initialize instance variables using the constructor

Last Updated : December 15, 2025

Problem Solution

In this program, we will initialize instance variables using the constructor and print the value of created variables in the show() method.

Program/Source Code

The source code to initialize instance variables using the constructor is given below. The given program is compiled and executed successfully.

# Ruby program to initialize instance variable 
# using constructor

class Sample
	def initialize
		@ins_var1 = "ABC";
		@ins_var2 = "XYZ";
	end
	
	def show
		print "ins_var1: ",@ins_var1,"\n";
		print "ins_var2: ",@ins_var2,"\n";
	end
end

obj = Sample.new();
obj.show();

Output

ins_var1: ABC
ins_var2: XYZ

Explanation

In the above program, we created a class Sample. The Sample class contains the constructor and show() method. We initialized the instance variables ins_var1, ins_var2 in the constructor and printed them inside the show() class.
