This compiles and runs:

import java.util.concurrent.atomic.AtomicInteger;

public class ThreadId { // Atomic integer containing the next thread ID to be assigned private static final AtomicInteger nextId = new AtomicInteger(0);

// Thread local variable containing each thread's ID private static final ThreadLocal<Integer> threadId = [ initialValue: { return nextId.getAndIncrement(); } ] as ThreadLocal<Integer>; // The Semi-colon at the end of the prior line seems to be required.

// Returns the current thread's unique ID, assigning it if necessary public static int get() { System.out.println( "Thread ID: " + threadId.get()); return threadId.get(); }

public static void main( String[] args ) { 1.upto(3) { Thread.start { new ThreadId().get(); } } }

}

Hello,

I have the following class:

import java.util.concurrent.atomic.AtomicInteger;

public class ThreadId { // Atomic integer containing the next thread ID to be assigned private static final AtomicInteger nextId = new AtomicInteger(0);

// Thread local variable containing each thread's ID private static final ThreadLocal<Integer> threadId = new ThreadLocal<Integer>() { @Override protected Integer initialValue() { return nextId.getAndIncrement();

} }

// Returns the current thread's unique ID, assigning it if necessary public static int get() { System.out.println( "Thread ID: " + threadId.get()); return threadId.get(); }

public static void main( String[] args ) {

new ThreadId().get();

}

}

What is the groovy equivlent of this java construct in th above class?:

// Thread local variable containing each thread's ID private static final ThreadLocal<Integer> threadId = new ThreadLocal<Integer>() { @Override protected Integer initialValue() { return nextId.getAndIncrement();

} }

I am asking because no matter what I tried, Groovy does not recoginze the method initialValue().

Thanks.
