Hi,
Some more ideas. Would very much appreciate some feedback.
Thanks
----------------- atomics and volatile ------------------------
type T {
stop volatile bool
i atomic int
}
func T.ops() {
i++
++i
i = 3 ? 1;
i--
i += 1
i -= 2
v := i
v = i++
}
func T.Stop() {
stop = true
}
Translates to
public final class T {
volatile boolean stop;
AtomicInteger i = new AtomicInteger();
final void incr() {
i.getAndIncrement();
i.incrementAndGet();
i.compareAndSet(3, 1);
i.getAndDecrement();
i.addAndGet(1);
i.addAndGet(-2);
int v = i.get();
v = i.getAndIncrement();
}
public final void Stop() {
stop = true;
}
}
---------------- importing Java types --------------------
// imported types can be given a local alias
// so in a way string is an alias for String
import java.util.ArrayList list
func foo() {
v := new list<string>()
v.add(“hello”)
v.add(“world”)
for x:v {
print(x)
}
}
translates to:
import java.util.ArrayList
public final class Statics {
static void foo() {
ArrayList<String> v = new ArrayList<String>();
v.add(“hello”);
v.add(“world”);
for (String x:v) {
System.out.println(x);
}
}
}
--------------------- Discarding exceptions ----------------------
// Support a syntax for discarding exceptions
func foo() {
try Thread.sleep(2) // silently consumes InterruptedException
}
translates to:
public final class Statics {
static void foo() {
try {
Thread.sleep(2)
} catch (Exception e) {
// ignored
}
}
}
------------------------ Exceptions ----------------------------
import java.io.FileReader
// a default try/catch/finally block
// this might be too wierd !!!
func foo() {
f := new FileReader(“testfile”)
} catch e {
e.printStackTrace()
} finally {
try f.close()
}
translates to
import java.io.FileReader
public final class Statics {
static void foo() {
FileReader f = null;
try {
f = new FileReader(“testfile”);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (f != null) {
try {
f.close();
}
catch (Exception e) {
}
}
}
}
}
