Add array elements in Ruby

Last Updated : 20 Jul, 2021

In this article, we will learn how to add elements to an array in Ruby.
Method #1: Using Index

Ruby

# Ruby program to add elements  
# in array 
  
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Geeks"] 
  
str[4] = "new_ele";
print str

# in we skip the elements
str[6] = "test";

Output:

["GFG", "G4G", "Sudo", "Geeks", "new_ele"]

["GFG", "G4G", "Sudo", "Geeks", "new_ele", nil, "test"]

Method #2: Insert at next available index (using push() method) -

Ruby

# Ruby program to add elements  
# in array 
  
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Geeks"] 
  
str.push("Geeksforgeeks")
print str

Output:

 ["GFG", "G4G", "Sudo", "Geeks", "Geeksforgeeks"]

Method #3: Using << syntax instead of the push method -

Ruby

# Ruby program to add elements  
# in array 
  
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Geeks"] 
  
str << "Geeksforgeeks"
print str

Output:

 ["GFG", "G4G", "Sudo", "Geeks", "Geeksforgeeks"]

Method #4: Add element at the beginning -

Ruby

# Ruby program to add elements  
# in array 
  
# creating string using [] 
str = ["GFG", "G4G", "Sudo", "Geeks"] 
  
str.unshift("ele_1")
print str

Output:

 ["ele_1", "GFG", "G4G", "Sudo", "Geeks"]
