When referring to a class or interface in a package you need to
specify the package name in front of every class
name or interface
name in the package you want to access, like so, in the folder
~/jtw-tutorials/pkg
(i.e.\ in the pkg
package).
package
pkg;public
class
Cbegin
beginMain
var
pkg.inner.A a1 =new
pkg.inner.A(123); a1.meth1(); // prints out "meth1:123"var
pkg.inner.A a2 =new
pkg.inner.A(456); a2.meth2(); // prints out "meth2:456" pkg.inner.A.func(); // prints out "func:666"endMain
end
To avoid having to qualify each class name or interface name with it’s
package, you need to use the import
directive like so after the
package
declaration but before the definition of the class
or
interface
like so:
package
pkg;import
pkg.inner.*;public
class
Cbegin
beginMain
var
A a1 =new
A(123); a1.meth1(); // prints out "meth1:123"var
A a2 =new
A(456); a2.meth2(); // prints out "meth2:456" A.func(); // prints out "func:666"endMain
end
