الموضوعات المخطط لها

• javac turns .java into .class files holding bytecode, a portable instruction set.
• The JVM loads classes on demand, verifies them, then runs the bytecode.
• Bytecode is not machine code; the JVM interprets it, then compiles hot parts to machine code.
• "Write once, run anywhere" works because the JVM, not your code, is platform-specific.
