Question: Is it possible that adding more import statements to your java code could slow down the time it takes to load your classes into the JVM?

Answer: 
No, imports are only used in compilation to find class references. Add unused imports and they don't do anything. To put it another way:

```
import java.util.*;

```

simply means you can write:

```
Map map = new HashMap();

```

instead of:

```
java.util.Map map = new java.util.HashMap();

```

That's all it does.
Don't confuse the word "import" with "class loading". The import statement does not cause any code to be loaded into memory. It's just a convenience that allows you to refer to classes using their short name instead of typing the full class name (e.g, "Connection" instead of "java.sql.Connection").
