Monitor and Thread synchronization

Method inside a synchronized block

Report a typo

Here is a class named SomeClass:

class SomeClass {

    val lock = Any()

    @Synchronized
    fun method1() {

        // some statements

        method2()
    }

    fun method2() {

        // some statements

        synchronized(lock) {

            // do something useful
        }
    }
}

Select two correct statements.

Select one or more options from the list

method1 is synchronized on an object of SomeClass

If a thread invokes method2 from method1, it will never be locked by the synchronized block inside method2

A thread can always invoke method2 and execute the code before the synchronized block

If a thread executes the statements in method1, other threads cannot execute the statements in method2 inside the synchronized block
