Question

I want to call a method that returns a string value. Actually this string value is an instance variable, and run() method put the value of the string.

So, I want to call a method to get the string value updated by thread run() method..

How can I do it…?

Answer 1

class Whatever implements Runnable {
    private volatile String string;

    @Override
    public void run() {
        string = "whatever";
    }

    public String getString() {
        return string;
    }

    public void main(String[] args) throws InterruptedException {
        Whatever whatever = new Whatever();
        Thread thread = new Thread(whatever);
        thread.start();
        thread.join();
        String string = whatever.getString();
    }
}
