(a) Discuss significance of byte code.

Bytecode is the intermediate code that is generated by the Java compiler and executed by the Java Virtual Machine (JVM). Here are some of the significant benefits of bytecode in the context of Java:

  • Portability: Java bytecode is platform-independent, which means that it can be executed on any platform that has a JVM installed
  • Security: Bytecode provides an additional layer of security as it can be executed within a sandbox environment. This sandbox ensures that the bytecode cannot access system resources directly, which helps prevent malicious code from damaging the system.
  • Performance: While bytecode requires an additional step of interpretation or compilation by the JVM, it can be optimized for performance during this step. Additionally, the JVM can dynamically adapt its execution to improve performance based on the current system load and available resources.
  • Maintainability: Bytecode can be easily decompiled back into source code, which can help developers understand and modify existing code.
