As the first error message says you can do one of 2 things:
1) Catch the exception
2) Declare the exception as something you throw.
You tried the second and it doesn't work since you aren't allowed to
throw an exception from a run() method. So, you should instead do the
first suggestion - catch the exception and handle it gracefully. Try:
run() {
...
try {
Thread.sleep(150);
} catch (InterruptedException e) {
return;
}
}
