Hi i am trying to write a program which reads from a properties file the pr

Question

hi,
this is ayesha.
I am trying to write a program wherein i will be reading the value of a property from a properties file which will be true initially. I want to loop in there till the time when the value of the property is false.
The code is as follows:
public static void main(String[] args) {
          ReadingAPropertiesFile propers=new ReadingAPropertiesFile();
          propers.ReadingFileRegularly("F:\\ayesha.properties");
public String ReadingFileRegularly(String FilePath){
          Properties props = new Properties();
          String message;
          String filePath=FilePath;
          try {
props.load(new FileInputStream(filePath));
message = props.getProperty("ayesha");
     boolean theValue = Boolean.parseBoolean(message);
     while(theValue){
          System.out.println("trueeeeeeeeeeeeeeeeeeeeeee");
          Thread.sleep(60000);
          ReadingFileRegularly(filePath);
          catch(Exception ex){
               ex.printStackTrace();
          String messagean="something";
          return messagean;
The contents of ayesha.properties are :
ayesha=true
After 5 minutes it will be set to false so i want to loop in there till the value of ayesha=false at which time i will return
But i dont know how to loop in there for that time:
while(theValue) ?????????????/ what after this???????????
Any suggestons are awaited.

Any suggestons are awaited.I think you better rethink your design , do not use recursion, I would normally use a loop like you did but without loading the content of the file each time, I would use File.l lastModified() method and compare with previous results from this method to see if the file was modified. Then if it was modified then load the new File and check if the property value has changed.
