An explicit import always goes before a wildcard import, so you could solve it as follows:
If you need both java.awt.List and java.util.List, you can only import one and use the fully qualified name for the other.
By the way, this is the reason I stopped using wildcard imports. Instead, I import each class I need explicitly. So far, only FileFilter has given me problems: java.io.FileFilter and javax.swing.filechooser.FileFilter sometimes contend, and java.io.FileFilter always loses out.
