I couldn't agree more with Craig. I have come across the exact
situation he describes, where there exists classes:
com.foo.a.ClassA
com.foo.a.Utils
org.bar.ClassB
and you have code:
// MyClass.java
package com.acme.c;
import com.foo.a.*;
import org.bar.b.*;
[...]
public void myMethod()
{
Utils = new Utils();
// etc.
}
If a class org.bar.b.Utils is added to a latter release of org.bar's
library, there is now an ambiguous reference to Utils. It appears that
most of the other arguments for or against explicit importing are
style- or ease-of-use related. That being the situation, the case
illustrated above should clinch the argument. import *; can result in
code that won't compile.
