Doubt in Inquisition question

[Jehaan Butt]

class A{
synchronized{System.out.println("Chess");} //1
{System.out.println("is");} //2
void hi(){System.out.println("a cool")} //3
static{System.out.println("game");} //4
}

Which lines do not compile?
a. Line 1
b. Line 2
c. Line 3
d. Line 4

The answer given is 1 and 3. 3 is obvious - there is no semicolon. But the reason given for line 1 is that "Synchronized is wrong here". What does that mean? Why exactly is synchronized wrong in this statement?

The synchronized block cannot be placed outside a method. Furthermore you need to synchronize over an object. System.out.println() does not return an object.

... you need to synchronize over an object. System.out.println() does not return an object.

To clarify, the syntax needs to be:

   void anyMethod() {
      nonSyncCode();

      synchronized (anyObject) {
          syncCodeGoesHere();
      }

      moreNonSyncCode();
   }
