GetField() NoSuchFieldException

Question

Hello,
I'm learning Java and I have problem with Reflection. My code:
import java.lang.reflect.Field;
public class TestReflection {
     public String name = new String("John");
     public TestReflection () {
          Field param = this.getClass().getField("name");
When I try to execute this code, I get NoSuchFiedlException. I must be doing something wrong...
Thanks,
Rok

I distinguish beetween compilation and execution. I didn't express myself in the right way. When I try to compile the code this is what I get:
C:\Users\rok.kreslin.notebook\workspace\Ucenje\src>javac TestReflection.java
TestReflection.java:9: unreported exception java.lang.NoSuchFieldException; must be caught or declared to be thrown
Field parameter = this.getClass().getField("name");

This is much more informative. It's telling you that "getField()" can throw a checked exception, so you either need to catch it (surround it with a try/catch block) or declare it (use a "throws" clause in the method declaration). Do you know what checked exceptions are?
