The Bean is :
package example_h;
import java.util.*;

public class CalBean
{
private double[] num;
public CalBean()
{
num = new double[2];
num[0] = 1;
num[1]=2;
}
public double getAverage()
{
double sum = 0;
for (int i=0;i

calculate data




Arrays

averrage:





The running result is

Arrays 45.046.047.0 averrage:
2.0

the average value is calculated properly however the array value displayed wrongly .
I do not quite understand on


There is no numList property in Bean , but actual 1,2,3 has passed to bean correctly .

Could someone give a hint?

    The numList property is derived from the accessor methods as follows...

    getX
    setX

    x is the property name.

    so...

    setNumList
    getNumList

    numList is taken to be the property name.
