Last Updated : 28 Apr, 2025

The replace() is an inbuilt function in julia that is used to replace a word or character with the specified string or character.

Syntax:

replace(s::AbstractString, pattern=>Word; count::Integer)

Parameters:

s::AbstractString: Specified string.
pattern=>Word: Pattern is searched from the given sentence and then that pattern is replaced with the word.
count::Integer: It is a number that is the count of specified pattern available in the sentence.

Returns: It returns a new sentence with replaced words.

Example 1:

# Julia program to illustrate 
# the use of String replace() method

# Getting a new sentence with replaced words
println(replace("GFG is a CS portal.", "CS" => "Computer Science"))
println(replace("GeeksforGeeks is a CS portal.", "GeeksforGeeks" => "GFG"))

Output:

Example 2:

# Julia program to illustrate 
# the use of String replace() method

# Getting a new sentence with replaced words
println(replace("GFG Geeks.", "GFG" => "GeeksforGeeks", count = 1))
println(replace("GFG Geeks GFG.", "GFG" => "GeeksforGeeks", count = 2))

Output:
