Ciao, Sheldon. public class TestThreads extends Thread { private long sleepMillis; public TestThreads(long sleepMillis) { this.sleepMillis = sleepMillis; } public void run() { try { Thread.sleep(sleepMillis); } catch (InterruptedException e) { } } public static void main(String[] args) { int threadCount = 0; long sleepMillis = 0; try { threadCount = new Integer(args[0]).intValue(); sleepMillis = new Long(args[1]).longValue(); } catch (Exception e) { usage(); } int i = 0; try { for (i = 0; i < threadCount; i++) { TestThreads test = new TestThreads(sleepMillis); test.start(); } System.out.println( "TestThreads: successfully fired " + threadCount + " threads" ); } catch (OutOfMemoryError e) { System.out.println("TestThreads: after creating " + i + " threads: " + e.getMessage()); } try { Thread.sleep(sleepMillis); System.out.println("TestThreads: waited " + sleepMillis + " milliseconds for all threads to complete"); } catch (InterruptedException e) { } } private static void usage() { System.err.println("usage: TestThreads threadCount sleepMillis"); System.exit(1); } }
