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.
No. Imports are purely a compile time construct ... syntactic sugar.

The imports tell the Java compiler how to map identifiers in the source code to fully qualified class names. But if the source code does not use an imported class, the bytecode file will have no references to it. Hence, a redundant import does not (and cannot) impact on class load times.
