Question

Is there a Java equivalent to the C# using keyword, as used in the following example?

namespace TheirNamespace
{
    public class ContestedClassName
    {
    }
}

namespace MyNamespace
{
    public class ContestedClassName
    {
    }
}

namespace MyBoundaryNamespace
{
    using MyRenamedClass = MyNamespace.ContestedClassName;
    using TheirRenamedClass = TheirNamespace.ContestedClassName;

    public class Translator
    {
        public TheirRenamedClass Translate(MyRenamedClass value)
        {
            return null;
        }
    }
}

Answer 1

No, that can’t be done in Java, you need to use fully qualified classnames in that case.

E.g.

public TheirNamespace.ContestedClassName translate(MyNamespace.ContestedClassName value) {
}
