Error in ADT class

Question

I have created an ADT class Bus with all the methods necessary. A method in this class will be called in a method in another class 'Terminus'. This method(in 'Terminus') will filter records place of travel wise on any day listing the buses.
But I seem to have a problem in this method (Bus class) when i try to compile the Bus class. The method is shown below:
public boolean isGoing(String place){
for(int i=0; i<places.size(); i++){
if(((String)(places.get(i))).compareTo(place)==0) break;
if(i==places.size()) return false;
else
return true;
The error message that pops up says that this method does not have a return statement.
The whole code for this class(Bus class) is :
* Class to initialize all the variables in bus.
* @param busnum : bus number
* @param s_time : start time
* @param places : places of travel by user
* @param dayorder : To store the dayorder according to String array days
* @author (AIGINI)
* @version (a version number or a date)
import java.util.*;
public class Bus
private String busnum, company;
private Time s_time;
private Vector places;
private String days[] = { "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday" };
private int dayorder;
/**To set an empty constructor in Bus*/
public Bus() { setData (null, null, null, null, 0); }
/**To set a proper constructor for class Bus*/
public Bus (String b, String c, Time st, Vector p, int dy) {
setData(b, c, st,p, dy);
/**To create a set method for class Bus*/
private void setData(String b, String c, Time st, Vector p, int dy)
busnum = b;
company = c;
s_time = st;
places = p;
dayorder = dy;
/**To get the bus number from user*/
public String getBusnum()
return busnum;
/**To get company name from user*/
public String getCompany()
return company;
/**To get start time from user*/
public Time getS_Time()
return s_time;
/**To get places from user*/
public Vector getPlaces(){
return places;
/**To get day order from user*/
public int getDayorder()
return dayorder;
/**to return true or false when moving from one place to another*/
public boolean isGoing(String place){
for(int i=0; i<places.size(); i++){
if(((String)(places.get(i))).compareTo(place)==0) break;
if(i==places.size()) return false;
else
return true;
/**To return output*/
public String toString()
return busnum + "\t" + company + "\t" + dayorder + "\t" + s_time + "\t" + places;

But I seem to have a problem in this method (Bus
class) when i try to compile the Bus class. The
method is shown below:
public boolean isGoing(String place){
for(int i=0; i<places.size(); i++){
f(((String)(places.get(i))).compareTo(place)==0)
break;
if(i==places.size()) return false;
else
return true;
error message that pops up says that this method
does not have a return statement.
public boolean isGoing(String place) {
    for(int i=0; i<places.size(); i++) {
        if(((String)(places.get(i))).compareTo(place)==0) break;
        if(i==places.size()) // this cannot happen!
            return false;
        else
            return true;
    // This is where the code continues if the 'break;' statement is excecuted
    // What will be returned?
}Perhaps the following is more appropriate:
public boolean isGoing(String place) {
    return places.contains(place);
}
