+ | Creating a new instance of the Vector class is done by invoking the method new on the class object. | ||
+ | |||
+ | < | ||
+ | >def aVector := Vector.new() | ||
+ | >>< | ||
+ | </ | ||
+ | |||
+ | All constructors defined in the corresponding Java class can be accessed too. For example, | ||
+ | |||
+ | < | ||
+ | >aVector := Vector.new(30) | ||
+ | >>< | ||
+ | </ | ||
+ | |||
+ | ===== Invoking methods on Java objects ===== | ||
+ | In a similar fashion to calling constructors on Java classes we can also call other methods defined in the Java class. | ||
+ | |||
+ | < | ||
+ | >1.to: 10 do: { |i| aVector.add(i) } | ||
+ | >>nil | ||
+ | >aVector | ||
