Explain the concept of cross-platform application development in Java and how it differs from other approaches.

Multiplatform application development in Java means that the same code can run on different devices and operating systems without changes. This is possible thanks to the Java Virtual Machine (JVM), which runs bytecode — an intermediate code compiled from Java programs.

The difference from other approaches is that there is no need to write separate code for each platform (for example, Android, Windows, macOS). Instead, one code is written, which the JVM adapts to the specific system.

Example: you wrote a program in Java, compiled it into bytecode, and this bytecode can be run on any device with a JVM installed, whether it’s a computer or a smartphone.
