Ruby program to create multiple threads

Program/Source Code:

The source code to create multiple threads is given below. The given program is compiled and executed on Windows 10 Operating System successfully.

# Ruby program to create multiple threads

# First Thread method
def ThreadFun1()
	$i = 0;
	while $i<5 do
		puts "First Thread running";
		$i += 1;
	end
end

# Second Thread method
def ThreadFun2()
	$i = 0;
	while $i<5 do
		puts "Second Thread running";
		$i += 1;
	end
end

# Create thread objects
t1 = Thread.new{ThreadFun1()};
t2 = Thread.new{ThreadFun2()};

# Join created thread.
t1.join();
t2.join();

Output:

First Thread running
First Thread running
First Thread running
First Thread running
First Thread running
Second Thread running
Second Thread running
Second Thread running
Second Thread running
Second Thread running

Explanation:

In the above program, we created two methods ThreadFun1(), ThreadFun2(). Then we bound the methods with thread objects. After that, we used the join() method to execute threads and printed appropriate messages.
