Hi Malli,

Please find the following solution which is tested - 

Controller Class:  
public class SeatBookingContrl {
    public List<Integer> selSeats {get;set;}
    public Integer totSeats {get;set;}
    List<Seat> appliedSeats;
    
    public SeatBookingContrl() {
        totSeats = 0;
    }
    public List<Seat> getSeats() {
        Seat s1 = new Seat();
        s1.seatNum = 1;
        s1.seatName = 'r1';
        Seat s2 = new Seat();
        s2.seatNum = 2;
        s2.seatName = 'r2';
        Seat s3 = new Seat();
        s3.seatNum = 3;
        s3.seatName = 'r3';
        Seat s4 = new Seat();
        s4.seatNum = 4;
        s4.seatName = 'r4';
        appliedSeats = new List<Seat>{s1,s2,s3,s4};
        return appliedSeats;
    }
    
    public void submit() {
        selSeats = new List<Integer>();
        for(Seat appSeat : appliedSeats) {
            if(appSeat.isSelected) {
                totSeats++;
                selSeats.add(appSeat.seatNum);
            }
        }
    }

    //Wrapper/Inner class to hold the seat information
    public class Seat {
        public Integer seatNum {get;set;}
        public String seatName {get;set;}
        public Boolean isSelected {get;set;}
        public Seat() {
            IsSelected = false;
        }
    }
}

Apex Page:  
<apex:page controller="SeatBookingContrl">
    <apex:form id="frm">
        <apex:pageBlock title="Book a Seat">
            <apex:pageBlockTable value="{!seats}" var="seat">
                <apex:column headerValue="Action">
                    <apex:inputCheckbox value="{!seat.isSelected}"/>
                </apex:column>
                <apex:column value="{!seat.seatName}" headerValue="Seat Name"/>
            </apex:pageBlockTable>
            <apex:outputPanel id="infoPanel">
                <apex:outputText>Number of seats selected: {!totSeats}</apex:outputText><br/>
                <apex:outputText>Selected seat numbers: <apex:repeat value="{!selSeats}" var="selSeat">{!selSeat};</apex:repeat></apex:outputText>
            </apex:outputPanel>
            <apex:pageBlockButtons location="bottom">
                <apex:commandButton value="Submit" action="{!submit}" reRender="infoPanel"/>
            </apex:pageBlockButtons>
        </apex:pageBlock>
    </apex:form>
</apex:page>
