Object

Object is a separate basic type. An object value has named methods and fields. Methods and fields are in the same symbol space. A class both defines an object type and provides a way to construct an object. Apply new operator to a class to get an object. Call method using obj.foo(args). Access field using obj.x.

 
import ballerina/io;

class MyClass {
    int n;

    function init(int n) {
        self.n = n;
    }

    function func() {
        self.n += 1;
    }
}

public function main() {

    MyClass x = new MyClass(1234);

Apply new operator to a class to get an object.

 
    x.func();

Call method using obj.foo(args).

 
    int n = x.n;

Access field using obj.x.

 
    io:println(n);
}
