Wrapper class Example for displaying Int and String

Wrapper class for displaying Int and String Datatypes

A Wrapper class is a class whose instances are a collection of other objects. It is used to display different objects on a Visual Force page in the same table.

Visualforce page:

<apex:page sidebar="false" controller="WrapperIntStringDisplayClassTest">
<apex:form >
<apex:pageBlock >
<apex:pageBlockSection >
<apex:pageBlockTable value="{!lstwrapperIntString}" var="w">
<apex:column headervalue="Action">
<apex:inputcheckbox />
</apex:column>
<apex:column headervalue="TestingName">
{!w.Tname}
</apex:column>
<apex:column headerValue="TestingCity">
{!w.Tcity}
</apex:column>
<apex:column headervalue="DataLoadCountry">
{!w.Dcountry}
</apex:column>
<apex:column headerValue="DataLoadPhone">
{!w.Dphone}
</apex:column>
</apex:pageBlockTable>
</apex:pageBlockSection>
</apex:pageBlock>
</apex:form>
</apex:page>

Apex class:

public with sharing class WrapperIntStringDisplayClassTest {
	List<Testing__c> lsttest = new List<Testing__c>();
	List<DataLoadTest__c> lstdlt = new List<DataLoadTest__c>();
	public List<wrapper> lstw = new List<wrapper>();
	public List<wrapper> getLstwrapperIntString() {
		lsttest = [select name,city__c from Testing__c];
		lstdlt = [select country__c,phone__c from DataLoadTest__c];
		for(Integer i=0;i<lstdlt.size();i++){
			lstw.add(new wrapper(lsttest[i].name,lsttest[i].city__c,lstdlt[i].country__c,lstdlt[i].phone__c));
		}
		return lstw;
	}
	public class wrapper{
		public String Tname{get;set;}
		public String Tcity{get;set;}
		public String Dcountry{get;set;}
		public String Dphone{get;set;}
		public wrapper(String Tname,String Tcity,String Dcountry,String Dphone){
			this.Tname=Tname;
			this.Tcity=Tcity;
			this.Dcountry=Dcountry;
			this.Dphone=Dphone;
		}
	}
