Syntax: enu.find_all { |obj| block } Parameters: The function takes a block whose condition is used to find the elements. Return Value: It returns the items in the enum which satisfies the condition in the block. Iy t returns an enumerator if no block is given.Example 1:
# Ruby program for find_all method in Enumerable
# Initialize
enu = (1..10)
# Prints
enu.find_all { |obj| obj % 2 == 1}
[1, 3, 5, 7, 9]Example 2:
# Ruby program for find_all method in Enumerable
# Initialize
enu = [1, 7, 10, 11]
# Prints
enu.find_all
Enumerator: [1, 7, 10, 11]:find_all
