What Is Java?
Welcome to Java, one of the world's most popular programming languages.
Java is a high-level programming language that was first released by Sun Microsystems in 1995. It is designed to be easy to learn and use, making it a great choice for beginners.
Java stands out for being:
- Simple: its syntax is straightforward and clean;
- Portable: you can run Java programs on different types of computers without changing the code;
- Secure: it helps protect your computer and data from threats;
- Robust: Java is reliable and handles errors well.
A key part of Java is the Java Virtual Machine (JVM). When you write a Java program, it is converted into a special format called bytecode. The JVM reads this bytecode and runs your program on any computer that has the JVM installed. This is called "write once, run everywhere", because you only need to write your code once, and it can run on any device with a JVM.
Java's simplicity, portability, security, and reliability make it a strong foundation for learning programming and building real-world applications.
