This is a good example for array of text or etc.. in action form

code.
jsp page
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>

<%@ taglib uri="http://struts.apache.org/tags-bean" prefix="bean" %>
<%@ taglib uri="http://struts.apache.org/tags-html" prefix="html" %>
<%@ taglib uri="http://struts.apache.org/tags-logic" prefix="logic" %>
<html:html>
<head>

<title>GL Test</title>
</head>
<body>
<html:form action="/GlTest">
<% for(int i=0; i<2; i++){ %>
<html:text property='<%= "arrayForm[" + i + "].glCode"%>'/>
<html:text property='<%= "arrayForm[" + i + "].operatingUnit"%>'/>
<% }%>
<html:submit/>
</html:form>

</body>
</html:html>

action class

package com.scb.gltest;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class GlTestAction extends Action {

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
try {
System.out.println("This is my test for array of index");
GlTestForm glTestForm = (GlTestForm) form;

if (glTestForm != null) {
for (int i = 0; i < 2; i++) {
ArrayForm arrayform = glTestForm.getArrayForm(i);
System.out.println("gl code ="+ arrayform.getGlCode());
System.out.println("operating unit ="+arrayform.getOperatingUnit());

}
}

} catch (Exception e) {
e.printStackTrace();
}
return mapping.findForward("success");
}
}

action form
package com.scb.gltest;

import org.apache.struts.action.ActionForm;

public class GlTestForm extends ActionForm {

ArrayForm arrayForm[] = new ArrayForm[2];

public GlTestForm() {
// TODO Auto-generated constructor stub
for (int i = 0; i < 2; i++) {
arrayForm[i] = new ArrayForm();
}

arrayForm[0].setGlCode("mytestGL1");
arrayForm[0].setOperatingUnit("mytestoperting1");
arrayForm[1].setGlCode("mytestGL2");
arrayForm[1].setOperatingUnit("mytestoperting2");

}

public ArrayForm[] getArrayForm() {
return arrayForm;
}

public void setArrayForm(ArrayForm[] arrayForm) {
this.arrayForm = arrayForm;
}

public ArrayForm getArrayForm(int index) {
return this.arrayForm[index];
}

public void setArrayForm(int index,ArrayForm arrayForm) {
this.arrayForm[index].setGlCode(arrayForm.getGlCode());
this.arrayForm[index].setOperatingUnit(arrayForm.getOperatingUnit());
}

try {
/** Get the ServletContext * */
ServletContext servletContext = this.getServletContext();

/** Initialize the logger * */
loadInitLogging();

/** Initialize the PropertyFileReader * */
loadPropertyFileReader(servletContext);

/** Logs the JDBC information * */
displayJDBCInfo();

/** Loads the Master Table values * */
loadMasterTableValues();

/** This method tiggers 12 AM of everyday

variable hide inside method

public class Kirving{
private final int i = 10;
public static void main(String argv[]){
Kirving ki = new Kirving();
ki.go(3);
}
public void go(int z){
int i=z;
}
}

The above code compiled without error.My question is i is private variable declared but again same i is used inside go mehtod that means i was hidded inside go method or not?
