Processes may call the procedures in a monitor whenever they want to, but they cannot directly access the monitor's internal data structures from procedures declared outside the monitor. This rule, which is common in modern object-oriented languages such as Java, was relatively unusual for its t...
Causes the current thread to wait until another thread invokes thenotify()method or thenotifyAll()method for this object. In other words, this method behaves exactly as if it simply performs the callwait(0). The current thread must own this object's monitor. The thread releases ownership of...
a character string can be used anywhere a method expects to receive aStringobject. During execution, the Java platform creates aStringobject from the character string passed to theSystem.out.printlncall, but your program cannot call any of theStringclass methods because it did not instantiate...
7. Polymorphism:Polymorphism allows objects to exhibit multiple forms or behaviors. It allows different objects to respond differently to the same method call based on their specific implementations. Polymorphism promotes code flexibility, extensibility, and the ability to process objects of different types...
