Java awt package has a lot of libraries and with the help of few of its libraries you can actually capture your screen movement and store into image file.

I have implemented thread class in order to work the application on given interval.

public class App{
    public static void main(String[] args)throws Exception{
        System.out.println("Capturing start");
        int i=0;
        File file=new File("capture");
        if(!file.exists() || !file.isDirectory()){
            file.mkdir();
        }
        while(true){
            i++;
            Thread thread=new Thread(new CaptureThread(i));
            thread.start();
            Thread.sleep(5000);
            
            
        }
    }
}
