eclipse no java virtual machine found

Introduction??This chapter is about the memory area of the Java virtual machine can be divided into several parts, the book can be divided into five parts: heap, Stack, program counter, method area, local method stack??Where the heap contains an instance of the object??And often said the basic data type, and the object reference is stored in the stack, in fact, i

heap is not regular, and the used memory and idle memory are intertwined. The virtual machine must maintain a list and record which memory blocks are available, during allocation, a large enough space is found in the list and allocated to the object instance, and records in the list are updated. This allocation method is called"Free List ).The distribution metho

??This phrase feels like the nature of the GC .??????1. Procedure Counter (program Counter Register)??A program counter is a small amount of memory space that acts as a line number indicator of the bytecode that is being executed by the current thread . The bytecode interpreter works by changing the value of this counter to select the next byte-code instruction to execute, and the basic functions such as branching, looping, jumping, exception handling, thread recovery, and so on, need to rely on

Understanding of the Java Virtual machine stackThe virtual machine stack is the stack memory we know, and the stack memory is unique to the thread. The reference type stored in the local variable table in the stack memory is simply the memory address of the storage object. T

Ubuntu 8.04.1 server is installed on Vmware, and a virtual machine is cloned. Eth0 disappears and an eth1 error occurs. The reason is that Ubuntu records the MAC address of the NIC. The MAC address of the original VM is recorded as eth0. After cloning, VMWare assigns a new MAC address to the VM to avoid conflicts. In ubuntu, the newly discovered address is set to eth1. In ubuntu 7. X, the corresponding fi

Sometimes, the cloning function of the kvm/vmware virtual machine is used to quickly replicate the installed system. But after cloning, will find no eth0 network card. Workaround: 1.
