Wait function in Java

Question

So I am writing a Java code to represent a heap sort and to represent the operation I need to have a waiting function which will wait between different operation but I am no

Answer 1

There's a simpler ( But possibly not better ) way to sleep that I have been using:

public static void sleep(int amt) // In milliseconds
{
    long a = System.currentTimeMillis();
    long b = System.currentTimeMillis();
    while ((b - a) <= amt)
    {
        b = System.currentTimeMillis();
    }
}

This will essentially cause everything your program is doing to cease until the time runs out. It also can cause a bit of lag. You have been warned.
