Why is Java considered to be 'write once, run anywhere'?

Because Java code can run on all devices without modification
Because Java programs are compiled into bytecode, which can run on any device with a JVM
Because Java code does not require compilation
Because Java automatically adapts to the user's location and settings

The correct answer is: Because Java programs are compiled into bytecode, which can run on any device with a JVM

Java is considered to be 'write once, run anywhere' because its programs are compiled into bytecode, which can be executed on any device with a JVM (Java Virtual Machine). This means that the same code can be run on multiple platforms without needing to be modified, making it convenient for developers. Option A is incorrect because while Java programs can run on multiple devices, they may still require some modification depending on the specific platform. Option C is incorrect because Java code does require compilation. Option D is incorrect because Java does not have the capability to automatically adapt to a user's location and settings. This is not a feature of the language. Therefore, option B is the most accurate explanation for why Java is known as 'write once, run anywhere'.
