This operator checks if both the objects are pointing to the same memory location. ![]() This method checks the equality of contents between two objects. It is a method defined in the Object class. Explain the difference between equals() method and equality operator (++) in Java. It compiles parts of the bytecode having similar functionality simultaneously, reducing the code’s compilation time. Just-In-Time Compiler is used to improve the performance of an application during runtime. JVM = Runtime environment to execute Java bytecode It is an abstract machine providing a runtime environment in which the Java bytecode can be executed. JRE = JVM + Libraries to execute the application It is a package that provides the class libraries, JVM, and all the components required to run the Java application. JRE stands for Java Runtime Environment.It consists of JRE, JavaDoc, compiler, debuggers, etc. It is the environment that is used to develop Java applications.
