Class loader is a subsystem in JVM, which is primarily responasible for loading the java classes, there are 3 different class loaders :
A new frame is created each time a method is invoked. A frame is destroyed when its method invocation completes, whether that completion is normal or abrupt (it throws an uncaught exception). Frames are allocated from the Java Virtual Machine stack (§2.5.2) of the thread creating the frame...
" to supportnativemethods (methods written in a language other than the Java programming language). Native method stacks may also be used by the implementation of an interpreter for the Java Virtual Machine's instruction set in a language such as C. Java Virtual Machine implementations...
接着如果handleReplicas方法调用了另外一个isLocalDamaged方法,该方法里也有自己的局部变量,代码如图所示: 这个时候又会给isLocalDamaged方法创建一个栈帧,压入线程的Java虚拟机栈里,而且该方法的栈帧的局部变量表里会有个isDamaged变量,过程如图: 如果isLocalDamaged方法执行完毕,就会把该方法对应的栈帧从Java虚拟机栈...
jvm is a virtual machine that enables the execution of java bytecode. the jvm acts as an interpreter between the java programming language and the underlying hardware. it provides a runtime environment for java applications to run on different platforms and operating systems. what is the role ...
If no exception is thrown, objectref is popped from the operand stack of the current frame (§2.6) and pushed onto the operand stack of the frame of the invoker. Any other values on the operand stack of the current method are discarded. The interpreter then reinstates the frame of the ...
// is used later to set the java.vm.args PerfData string constant. // the -Djava.class.path and the -Dsun.java.command options are // omitted from jvm_args string as each have their own PerfData // string constant object. build_jvm_args(option->optionSt...
entry = CAST_FROM_FN_PTR(address, InterpreterRuntime::resolve_get_put); break; // ... default: fatal(err_msg("unexpected bytecode: %s", Bytecodes::name(bytecode())); break; } // __ movl(temp, (int) bytecode()); __ call_VM(noreg, entry, temp); // /...
When an object in the heap calls a method, the method runs in the virtual machine stack, program counter, and local method stack. 1.5.3 Execution Engine When the code in the method is executed, the code is executed by the "interpreter" in the execution engine; the frequently called code...
