Pattern / best practice for accessing connection that has undeterministic set time

Below code attempts to get a connection every 5 seconds. The getConnection method returns true or false depending on random double and is for illustrative purposes. The time it takes to get a connection cannot be guaranteed so if fail to initially get connection, wait 5 seconds and try again. Once the connection is attained, then just exit.

Is there better/cleaner method of getting the connection instead of using if statements and Thread.sleep ? It seems wrong (im not sure why) sleeping the running thread for 5 seconds before trying again

public class TestAlive {

    public static void main(String args[]) {

        while (true) {
            try {
                if (getConnection()) {
                    System.out.println("Got connection, do some work.....");
                    System.exit(0);
                }
                else {
                    System.out.println("No connection, re-trying in 5 seconds");
                    Thread.sleep(5000);
                }
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    public static Boolean getConnection() {
        return Math.random() > 0.5;
    }
}
