GNU Java Training Wheels 2.0: Moving a class into a sub-package

Suppose you want to move a class A from no package (the folder ~/jtw-tutorials) to a package called for argument’s sake pkg.inner, the steps from Moving a class into a package needs to be followed, the only difference being that the package spec needs to be changed to package pkg.inner; and the file needs to be moved into the folder pkg/inner. To run the class file you need to invoke the following Make command:

package pkg.inner;

public class A
begin
    public property int data;

    public classVar int data2 = 666;

    public constructor A(int d)
    begin
        data = d;
    end

    public method void meth1()
    begin
        System.out.println("meth1:" + data);
    end

    public method void meth2()
    begin
        System.out.println("meth2:" + data);
    end

    public function void func()
    begin
        System.out.println("func:" + data2);
    end

    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
