Java's design, allowing programs to run on different platforms without modification. It's like a translator that speaks many languages.

A powerful feature allowing parts of your program to run independently, like multiple tasks happening at once. It's efficient for complex programs.

Java prevents common errors like memory leaks or unexpected crashes during program execution. It's like a safety net for your code.

Java's ability to handle errors gracefully without stopping the whole program. It's like a plan for dealing with unexpected situations.

Java's object model is simple and expandable, while keeping basic data types optimized for speed. It's like a modular design system.

The process of converting a Java program into a platform-independent intermediary language that can be understood and executed by the Java Virtual Machine (JVM).

A software environment that provides the runtime environment for Java programs by executing Java bytecode, making Java applications platform-independent.

A key feature of Java that ensures program execution safety by restricting the program's access to system resources and preventing unauthorized actions.

A language designed to be easy to learn and use, especially for programmers familiar with object-oriented principles.

A feature of Java that emphasizes the importance of making programs secure from data breaches and malicious code execution.

A characteristic of Java allowing programs to run consistently on various operating systems without requiring code modifications.

A core design principle of Java that incorporates object-oriented programming concepts, promoting code reusability, modularity, and data encapsulation.

A design feature of Java focusing on robust code that is reliable and free from errors, aiming to prevent unexpected program crashes or malfunctions.

Java code is executed on different platforms using the Java Virtual Machine (JVM), which acts as an intermediary.

Java programs are designed to be highly efficient and run quickly.

Java is designed for distributed environments like the internet, allowing programs to communicate and share resources.

Java programs can be extended and modified easily due to its flexible nature.

Java programs can be protected from security threats by using secure features within the language.

A mechanism that combines code and data, protecting them from outside interference. think of a safe box for your program's secrets.

Classes define the shared structure and behavior of objects, which are like individual instances of that class. Objects have physical reality, while classes are logical.

Data defined by the class are called member variables or instance variables. The code operating on them is called member methods or just methods.

Inheritance lets an object inherit properties from another object, creating a hierarchical relationship for efficient code reuse.

Polymorphism means 'many forms'. It allows one interface to handle different actions based on the context.

Polymorphism means 'many forms'. It allows one interface to handle different actions based on the context. It is often expressed as 'one interface, multiple methods'.

Polymorphism allows for flexible code design, where a single interface can be used for a group of related activities. For example, a stack can handle different data types.

A last-in, first-out list where the most recently added item is the first one to be removed, like a stack of plates.

Polymorphism is the ability of a program to treat objects of different types in a uniform way. It allows you to write flexible code that can handle various objects without explicitly knowing their specific types.

The Java compiler automatically selects the appropriate method based on the type of object being used. You don't need to manually choose, just use the general interface.

A Java source file is a text file with a .java extension that contains class definitions and other code. The compiler will use this file to generate bytecode.

javac is the Java compiler. It takes a Java source file (.java) as input and produces bytecode - a platform-independent intermediary language (.class) that the JVM understands.

The Java Virtual Machine (JVM) is a software environment responsible for running Java bytecode. It acts as an intermediary between the program and the operating system.

The 'java' command is used to execute Java programs. You need to provide the class name as an argument to run the compiled program.

Multiline comments in Java are denoted using the symbols /* and */. They are used to add explanations and make the code more readable.

The first line of a Java program is typically a class declaration. It defines a class named 'Example' which contains the main method, the entry point of the program.

A programming construct that allows the execution of different blocks of code based on the value of a variable. It's like a decision-making tool that chooses which path to follow.

The default case is executed if none of the other cases match the value of the variable. Think of it as a catch-all option.

A block of code within a switch statement that is executed if the value of the variable matches the case label. Like a specific route based on the value.

A statement that tells the program to stop executing the current switch statement. It prevents the program from accidentally executing other cases. Like a stop sign in a multi-lane road.

A sequence of programming statements that execute repeatedly until a specific condition is met. Think of it like a loop that keeps going until it reaches the end.
