Iteration Order for Maps and Sets Is Now Predictable (Summer 15 Release Update)

Hi Guys,

  1. Until this Spring 15 release, Maps and Sets are Unordered Collections. So the returned order will be random.
  2. But beginning from Summer 15 release onwards, Maps and Set order is predictable. The order will be same that what you put from the beginning to end.
 Map<String, String> orderedMap = new Map<String, String>();
 orderedMap.put('Good', 'This is so good');
 orderedMap.put('Bad', 'This is so bad');

If you run the above code snippet in Developer console you will get the returned order as below,

Until Spring 15 Release:

{Bad=This is so bad, Good=This is so good}

From Summer 15 Release:

{Good=This is so good, Bad=This is so bad}

This changes is not the API level, this is Schema level change. If anyone relying on the Map or Set order in your codes, change it as soon.


Different Ways Of Using Apex:Param Tag


What Is Parm Tag?
<apex:Param> :- apex:param tag is used to hold java Script values.
param means parameter. This tag is also used to Pass values from 
java Script to an Apex controller. 

The <apex:param> component can only be a child of the following components:

  • <apex:actionFunction>
  • <apex:actionSupport>
  • <apex:commandLink>
  • <apex:outputLink>
  • <apex:outputText>
  • <flow:interview>


 <apex:param name="ParamName" value"{!someValue}" assignTo="{!someproperty}"/> 

value : Required = T R U E

Ques)So, When To Use assingTo & value And How To Use It?
If you use value u can set the value to the query string param name like

<apex:param name="ParamName" value"1234"/> 

& Now, You can access this value in the controller using

Integer res=apexpages.currentpage().getparameters.get('ParamName');


If you use assingTo attribute then this will asigen the value to a property in the controller.
In Visualforce Page:

 <apex:param name="ParamName" value"{!someValue}" assignTo="{!someproperty}"/> 

In The Controller:

public string someproperty {get;set;} 

Now The Value What is Present in Value shall be assign to someproperty



<apex:page controller="paramexample">
 <apex:form >
 <apex:pageblock >
<apex:pageblockTable title="Accounts" value="{!acclist}" var="a">
<apex:column headervalue="Account name">
<apex:commandlink reRender="out" action="{!Paramdemo}">
<apex:param name="aid" value="{!}" assignTo="{!accname}"/>
<apex:column value="{!}"/>
<apex:column value="{!a.industry}"/>

<apex:outputpanel id="out">
accname = {!accname}

public class paramexample
public string accname{get;set;}
public list<account> acclist { get; set; }

public paramexample(){
acclist = new list<account>();
for(account a : [select id, name, phone, industry from account limit 20])

public void Paramdemo() {}

Automatically shows the Choose file Option / Button when a checkbox is selected.

whenever I select/check the checkbox (checkbox value=true) then the ChooseFile (inputfile) should display/show automatically .

Vf code:

<apex:page controller="example23">

<apex:form >

 <apex:inputCheckbox value="{!option}" >
<apex:actionsupport event="onclick" action="{!change}" />

<apex:actionRegion rendered="{!bool}">

<apex:inputFile value="AttachFile" />



Apex Controller:

public class example23 {

 public Boolean bool { get; set; }
 public Boolean option { get; set; }
 public PageReference change() {
 if(option == true)
 bool = true; 
 bool = false; 
 return null;

public example23(){
bool =false;

Using Trigger Updating Lookup filed.

To Update the Lookup field, Using Trigger Before Insert, Before Update.

Here I’am assuming Opportunity as Child and Budget_Master__c as Parent Object.
The Criteria is The From_Date__c(Date filed) & To_Date__c(Date filed) From Budget_Master__c must be in the range of given Opportunity RecCreatedDate__c(Datetime field)

trigger UpdateLookup on Opportunity (Before Insert,Before update) {
if(trigger.isInsert || trigger.isUpdate){
set<Budget_Master__c> BudMaster = new Set<Budget_Master__c>([Select Id, Name, From_Date__c,To_Date__c From Budget_Master__c]);

for(Opportunity  Op :{
for(Budget_Master__c BM :BudMaster ){
system.debug('------BFR IF---- ');
system.debug('------RecCreatedDate : '+(Op.RecCreatedDate__c).date());
 system.debug('------From: ' +BM.From_Date__c);
 system.debug('------ToDt: '+BM.To_Date__c );
If(  (((Op.RecCreatedDate__c).date()) >= BM.From_Date__c) && ((Op.RecCreatedDate__c).date()) <=(BM.To_Date__c)) {
system.debug('------InSide IF---- ');
}//If closed
}//Inner for CLOSED
}//outer for CLOSED
}//if(trigger.isInsert || trigger.isUpdate) CLOSED
}//Trigger closed

Trigger On Account Object

trigger ChangingFirstlttrUpper on Account (before insert,before update) {
      if(trigger.isBefore )
         if(trigger.IsInsert ||trigger.IsUpdate )

Apex Class

global class ChanignToCaps{
   global static void Change( Account [] acc){
      for(Account a :acc){
         if(a.Name!=null || a.Name != ' '){
   if(a.BillingStreet != null )
    a.BillingStreet = formatToUpper(a.BillingStreet);

   if(a.BillingCity !=null)
    a.BillingCity = formatToUpper(a.BillingCity);

   if(a.BillingState !=null )
    a.BillingState= formatToUpper(a.BillingState);

   if(a.BillingPostalCode !=null )
    a.BillingPostalCode = formatToUpper(a.BillingPostalCode);

   if(a.BillingCountry !=null )
    a.BillingCountry= formatToUpper(a.BillingCountry);

formatToUpper Is A Static Function Which Does The Acutal Work:

public static String formatToUpper (String Str) {
String result = '';
for (String iter : Str.split('[ ]+')) {
   if (iter != null && iter != '') {
    if (iter.length() > 1) {
     result += iter.substring(0,1).toUpperCase() + iter.substring(1,iter.length()) + ' ';
     result += iter.substring(0,1).toUpperCase() + ' ';
return result;
