/**
* @param args
*/
public static void main(String[] args) {
try {
dumpClassInfo("java.lang.String");
dumpClassInfo("com.effectivejava.rtti.ClassExtractor");
dumpClassInfo("com.effectivejava.rtti.ClassExtractorTest");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
这里有另外一个供测试的类：
[java]
public class ClassExtractorTest extends ClassExtractor implements Runnable,
Serializable, Cloneable {
/**
*
*/
private static final long serialVersionUID = -5054007892592227440L;
private String name;
private static long uid;
public ClassExtractorTest() {
// TODO Auto-generated constructor stub
}
public void run() {
// TODO Auto-generated method stub
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
}
public void goToSomewhere() {
}
public static void die() {
}
private void cannotSeeThis() {
}
enum Direction {
North,
West,
};
private class InnerClass {
}
private static class StaticInnerClass {
}
}
运行结果：
