Listing the Property Names of a Bean</h3>
This example determines the properties of a bean with the type <code>MyBean</code>.
<pre>
try {
BeanInfo bi = Introspector.getBeanInfo(<font color="#0066ff"><i>MyBean</i></font>.class);
PropertyDescriptor[] pds = bi.getPropertyDescriptors();
for (int i=0; i<pds.length; i++) {
// Get property name
String propName = pds[i].getName();
}
// class, prop1, prop2, PROP3
} catch (java.beans.IntrospectionException e) {
}
public class <font color="#0066ff"><i>MyBean</i></font> {
// Property prop1
public String getProp1() {
return null;
}
public void setProp1(String s) {
}
// Property prop2
public int getProp2() {
return 0;
}
public void setProp2(int i) {
}
// Property PROP
public byte[] getPROP3() {
return null;
}
public void setPROP3(byte[] bytes) {
}
}
