Question

Which of the following statements are true? A condition is associated with a lock. To invoke methods on a condition, the lock must be obtained first. Once you invoke the await method on a condition, the lock is automatically released. Once the condition is right, the thread re-acquires the lock and continues executing. The signal method on a condition causes the lock for the condition to be released. A resource bundle is _____. serialized configuration data a Java source code that contains image, audio, and text files a database file a Java class file or a text file that provides locale-specific information Generics provide that allows programmers to catch invalid types at compile time. compile-time exception handling run-time type safety compile-time error checking compile-time type safety

Explanation / Answer

For question 18:

A resource bundle is a Java .properties file that contains locale-specific data. It is a way of internationalising a Java application by making the code locale-independent.

So option number 4.

For question 19:

Java Generic methods and generic classes enable programmers to specify, with a single method declaration, a set of related methods, or with a single class declaration, a set of related types, respectively.Generics also provide compile-time type safety that allows programmers to catch invalid types at compile time.

So correct options are 3 and 4.
