Last Updated : 07 Jan, 2020

clear() is an Hash class method which removes all the Hash elements from it.

Syntax: Hash.clear()

Parameter: Hashs to clear off

Return: Hash with all elements cleared

Example #1:

# Ruby code for clear() method 
  
# declaring Hash value 
a = {a:100, b:200} 
  
# declaring Hash value 
b = {a:100, c:300, b:200} 
  
# declaring Hash value 
c = {a:100} 
  
puts "clear a : #{a.clear()}\n\n"
  
puts "clear b : #{b.clear()}\n\n"
  
puts "clear b : #{c.clear()}\n\n"

Output :

clear a : {}

clear b : {}

clear b : {}

Example #2:

# Ruby code for clear() method 
  
# declaring Hash value 
a = { "a" => 100, "b" => 200 } 
  
# declaring Hash value 
b = {"a" => 100} 
  
# declaring Hash value 
c = {"a" => 100, "c" => 300, "b" => 200} 
  
puts "clear a : #{a.clear()}\n\n"
  
puts "clear b : #{b.clear()}\n\n"
  
puts "clear b : #{c.clear()}\n\n"

Output :

clear a : {}

clear b : {}

clear b : {}
