a program in javabean to implement indexed properties of a bean using simplebeaninfo class

Aim: write a program in javabean to implement indexed properties of a bean using simplebeaninfo.

Program:

PieC.java

package sunw.demo.indexed;

import java.awt.*;

import java.io.*;

public class PieC

{

            private double data[ ];

            public double getData(int index)

            {

                        return data[index];

            }

            public void setData(int index, double value)

            {

                        data[index] = value;

            }

            public double[ ] getData( )

            {

                        return data;

            }

            public void setData(double[ ] values)

            {

                        data = new double[values.length];

                        System.arraycopy(values, 0, data, 0, values.length);

            }

}

PieCBeanInfo.java

package sunw.demo.indexed;

import java.beans.*;

public class PieCBeanInfo extends SimpleBeanInfo

{

     public PropertyDescriptor[] getPropertyDescriptors()

       {

           try

               {

                    PropertyDescriptor data= new PropertyDescriptor("data",PieC.class);

                    PropertyDescriptor p[] = {data};

                    return p;

              }

          catch(Exception e)

              {

               }

          return null;

       }

}

Output:
