julialangHow to use constructors in JuliaLang?

Constructors are used to create objects in JuliaLang. They are functions that take arguments and return an object.

Example

struct Point
    x::Float64
    y::Float64
end

function Point(x, y)
    Point(x, y)
end

p = Point(1.0, 2.0)

Output example

Point(1.0, 2.0)

Code explanation

• struct Point: defines a new type called Point
• x::Float64 and y::Float64: define two fields of type Float64
• function Point(x, y): defines a constructor function for the Point type
• Point(x, y): creates a new Point object with the given x and y values
• p = Point(1.0, 2.0): creates a new Point object with x and y values of 1.0 and 2.0 respectively
