Question

New to java and have a question related to packages.

I like to keep objects organized in namespaces and ran into a problem with enums that I cannot figure out.

Say I have a nested enum like this:

package Project;
public class Foo
{
    public enum Bar { One, Two, Three };
}

I want to do something like this

package Project.Attributes;
public class Foo
{
    public setBar( Project.Foo.Bar bar ) {}
}

But I am getting name conflicts and unknown package ‘Foo’ errors.

How can I achieve this?

Answer 1

It should work after below corrections

1. semicolon after the package declaration
2. add void return type for setBar(…) method

One more suggestion is to use small case for package names.

package project;

public class Foo
{
    public enum Bar {
        One, Two, Three
    };
}


package project.attributes;

public class Foo
{
    public void setBar(project.Foo.Bar bar)
    {
    }
}
