If you overwrite clone(), which 3 rules must this method obey? - 1) the new object should be new: memory address should differ 2) Both should be an object of the same class 3) Both should be in the same state: ().equals(a) == true Why do we need to implement the Clonable interface? - At runtime it would throw the CloneNotSupportedException if we don't implement the Cloneable interface. A class implements the Cloneable interface to indicate to the O() method that it is legal for that met...

Java program is a set of instructions written in the Java programming language that tells the computer what to do. It typically consists of classes, methods, variables, and other programming constructs. Java programs are compiled into bytecode, which can then be executed by the Java Virtual Machine (JVM) on any platform, making Java a platform-independent language. Java programs are widely used for developing various applications, including web, mobile, desktop, and enterprise software.

Java is a widely-used, versatile programming language known for its simplicity, reliability, and platform independence. Originally developed by Sun Microsystems (now owned by Oracle Corporation) in the 1990s, Java has since become one of the most popular programming languages in the world.

Java is an object-oriented programming language renowned for its portability and versatility. Its syntax resembles that of C++, featuring semicolons to terminate statements and curly braces for code blocks. Java supports various data types including integers, floating-point numbers, characters, and booleans. Variables store data temporarily, while constants hold unchanging values. Java encourages object-oriented programming principles such as encapsulation, inheritance, and polymorphism. It empl...
