My Requirement is i have two pages in that one page have list of data if i select any one record that value to be display in page 2.

So i have created one controller (Apex Class) like below

public with sharing class Pages_Navigation 
{ 
    public Choosename chosenName;
public Choosename getChoosename()
{
    if(chosenName == null) chosenName = new Choosename();
    return chosenName;
}
public Job_Application__c[] getNumbers() 
{       
    try 
    {        
     
    Job_Application__c[] numbers = [select Name, Status__c  
                            from Job_Application__c order by Name limit :list_size 
                          offset :counter]; 
    return numbers;       
    } 
    catch (QueryException e) 
    {          
        ApexPages.addMessages(e);
        return null;       
    }    
}  
public PageReference step1() 
{    
    return Page.JAPage1;
}
public PageReference step2()
{   
    PageReference oPageRef = Page.JAPage2;
    oPageRef.setRedirect(true);
    oPageRef.getParameters().put('JobName',string.valueof(chosenName));
    return oPageRef ;   
}
public class Choosename
{
    public string Name {get;set;}
}
}

And Created pages like below
