Is Java Platform Independent if then how?Is Java Platform Independent if then how?May 09, 2025 am 12:11 AM

Java is platform-independent because of its "write once, run everywhere" design philosophy, which relies on Java virtual machines (JVMs) and bytecode. 1) Java code is compiled into bytecode, interpreted by the JVM or compiled on the fly locally. 2) Pay attention to library dependencies, performance differences and environment configuration. 3) Using standard libraries, cross-platform testing and version management is the best practice to ensure platform independence.
