1. Creation of Objects 1.1 class Load Check When a virtual opportunity comes to a new command, it first checks whether the parameter of the instruction can navigate to a class's symbolic reference in a constant pool, and checks whether the class represented by the symbolic reference has been loaded, parsed, and initialized. If not, the corresponding class loading process is performed first. 1.2 Allocating memory Divides a certain size of memory from

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

Since the work, the more written code, the program is increasingly bloated, less efficient, for me such a pursuit of the perfect programmer, this is absolutely not allowed, so in addition to constantly optimize the program structure, memory optimization and performance tuning has become my usual "trick." To perform memory optimization and performance tuning on Java programs, do not understand the internal principle of the
