hello Subha,

 

Just implement this code.

 

<apex:page controller="wrapchkcon">
     <apex:form >
         <apex:pageBlock >
             <apex:pageBlockButtons >
                 <apex:commandButton value="Selectednames" action="{!selname}"/>
             </apex:pageBlockButtons>
            <apex:pageBlockSection >
                <apex:pageBlockTable value="{!lstwrapper}" var="w">
                    <apex:column headerValue="CheckValue">
                        <apex:inputcheckbox value="{!w.checked}"/>
                    </apex:column>
                    <apex:column headerValue="Name">
                        {!w.names}
                    </apex:column>
                </apex:pageBlockTable>
            </apex:pageBlockSection>        
         </apex:pageBlock>
     </apex:form>
</apex:page>

 

 

 

class:

 

public with sharing class wrapchkcon {

    List<String> selectednames =new List<String>();
    public void selname()
    {
       
        for(wrapper w: lstwrapper)
        {
            if(w.checked==true)
            {
                selectednames.add(w.names);
            }
        }
        system.debug('************ Selected Names are **********'+selectednames);
       
    }


   
    List<Departmentt__c> lstdept=new List<Departmentt__c>();
    List<wrapper> lstwrapper=new List<wrapper>();
    wrapper w;
   
    public List<wrapper> getlstwrapper()
    {
        return lstwrapper;
    }
    public wrapchkcon()
    {
        lstdept=[select Id,name from Departmentt__c];
        for(Integer i=0;i<lstdept.size();i++)
        {
        w=new wrapper(lstdept[i].name);
        lstwrapper.add(w);
        }
       
    }
   
    public class wrapper
    {
        public String names{get;set;}
        public boolean checked{get;set;}
        public wrapper(String names)
        {
            this.names=names;
            checked=false;
        }
    }
}

You need to use the wrapper class. A very good documentation is here :

This is working fine, but if we unselect some items and select some more items, the previous ones are still shown in the debug log. Any resolution about that !
