synchronized(t) {
synchronized(t) {
System.out.println("made it!");
}
}
}
}
This program produces the output:
made it!
Note that this program would deadlock if a single thread were not permitted to lock a
monitor more than once.
14.20. The try statement
A try statement executes a block. If a value is thrown and the try statement has one or more
catch clauses that can catch it, then control will be transferred to the first such catch clause.
If the try statement has a finally clause, then another block of code is executed, no matter
whether the try block completes normally or abruptly, and no matter whether a catch clause
is first given control.
