How to add select check box after displaying Lead and Contact records in visualforce page

Hi All,
How to add select check box after displaying Lead and Contact records in visualforce page.
I have written the apex class and visual force page for displaying records both leads and contacts here is my code..........
apex class:
public class objectcontroller
{
    public List<selectOption> objects{get; set;}
    public string selected{get; set;}
    public List<contact> obj1{get; set;}
    public list<lead> obj2{get; set;}
    public boolean obj1Status{get; set;}
    public boolean obj2Status{get; set;}
    public objectcontroller()
    {
        obj1Status=false;
        obj2Status=false;
        objects= new List<selectOption>();
        objects.add(new selectOption('contact','contact'));
        objects.add(new selectOption('lead','lead'));
    }
    public pageReference getRecordofObject()
    {
         if(selected=='contact')
        {
            obj1=[select id,lastname,Email from contact limit 100];
            obj1Status=true;
        }   
        else
        {
            obj2=[select name,company,Status from lead limit 100];
            obj2Status=true;
        }
        return null;
    }
    
}

Visualforce page:
<apex:page controller="objectcontroller" showHeader="false">
    
    <apex:form >
        
        <apex:pageBlock title="Select a object">
            <apex:selectList value="{!selected}" size="1">
                <apex:selectOptions value="{!objects}"/>
            </apex:selectList>
            <apex:pageBlockButtons location="bottom">
                <apex:commandButton action="{!getRecordofObject}" value="Show Records" rerender="cb"/>
            </apex:pageBlockButtons>
        </apex:pageBlock>
        <apex:outputPanel >
            <apex:pageBlock id="cb">
                <apex:pageBlockSection >
                    <apex:pageBlockTable value="{!obj1}" var="ob1" rendered="{!obj1Status}">
                        <apex:column value="{!ob1.id}"/>
                        <apex:column value="{!ob1.lastname}"/>
                        <apex:column value="{!ob1.Email}"/>
                    </apex:pageBlockTable>
                </apex:pageBlockSection>  
                <apex:pageBlockSection >
                    <apex:pageBlockTable value="{!obj2}" var="ob2" rendered="{!obj2Status}">
                        <apex:column value="{!ob2.id}"/>
                        <apex:column value="{!ob2.company}"/>
                        <apex:column value="{!ob2.status}"/>
                    </apex:pageBlockTable>
                </apex:pageBlockSection>
            </apex:pageBlock>
        </apex:outputPanel>
    </apex:form>
</apex:page>

Hi Devi Chandrika,
 Thanks for the code and i have small modifications in the code can you help me with that......
Actually when i choose one object lead or contact only one object records should be displayed but two objects records are displaying can you help me with the requirment.......................

Hi Nihar,
You just have to make other object pageBlockTable rendered attribute to false.
Try this one. 
public pageReference getRecordofObject()
    {
         if(selected=='contact')
        {
            for(contact c :[select id,lastname,Email from contact limit 100]){
            wrapcon.add(new wrapcontact(c));
            }
            obj1Status=true;
            obj2status=false;
        }   
        else
        {
            for(lead l:[select name,company,Status from lead limit 100]){
                wrapLd.add(new wrapLead(l));
            }
            obj1status=false;
            obj2Status=true;
        }
        return null;
    }
