Ruby program to sleep thread execution for a specific time

Last Updated : December 15, 2025

Problem Solution

In this program, we will create two threads. Here, we will use the sleep() method to pause a thread for a specific time.

Program/Source Code

The source code to sleep thread execution for a specific time is given below. The given program is compiled and executed on Windows 10 Operating System successfully.

# Ruby program to sleep thread execution 
# for a specific time.

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

		# sleep thread for 1 second
		sleep(1);
	end
end

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

		# sleep thread for 1 second
		sleep(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
Second Thread running
Second Thread running
First Thread running
Second Thread running
First Thread running

Explanation

In the above program, we created two methods ThreadFun1(), ThreadFun2(). Then we bound the methods with thread objects. Here, we used the sleep() method to pause thread execution and printed the messages.
