How to stop program excecution...

Question

Hi..
I would like to know how I can stop the execution of a program, not using System.out.exit(..). I do not want the application be closed.
Let me be more specific..
My program reads text from a file and depending a condition (ie. if the length of the string is > 10 , a counter is incremented , errors++ ) and I want that when errors > 20 the program stops... I use a Class that inherits from Exception class and I use it to catch when errors > 20, but the program does not stop until the end of file in reached...
just a message is shown (ie. Too many errors...)
This is a very general idea of my program...
/*class constructors and call to starts method*/
public void starts(){
int errors;
String line;
   /* another declarations */ 
  while (!myFile.eof()){
    readString();
public void readString(){
    /* code...
    line=myFile.readLine();
    if(line.length()>10){
       try{
         countErrors();
       }catch(MyException e){
         System.out.println("Too many errors " + e);
public void countErrors()throws MyException{
    if((++errors)>20)           
       throw new MyException(errors);   
class MyException extends Exception{
int error;
     public MyException(int e){
          error=e;
     public String toString() {
         return "MyException[" + error+ "]";
}An also, I use recursion in another calls to other methods so, I need solve this problem...
Any help will be useful...thanks

Answer 1

instead of throwing an exception you could just check amount of erros in the while loop and ...
if(errors > maxerrors)break;
this will exit your while loop and stop the reading of the file.. so it wud look like :
public void starts(){
int errors;
String line;
/* another declarations */
while (!myFile.eof()){   
readString();
if(errors > 20) break; checks to c amount of errors and then breaks
// the break will then quit the while loop and cancel the file
// being read without quiting the program
public void readString(){   
/* code...
line=myFile.readLine();
if(line.length()>10) errors++;
