Read a lot of bloggers wrote the principle of heap sorting, are explained quite clear, is the code implementation (mainly the Java language) some people dazzling. I have re-organized the code implementation of the heap sort (Java).What are the problems and irregularities, but also hope that the partners remind me to co

Java memory can be divided into: heap and meta space. To View the heap: Jmap-heap PID View Metaspace: Use JSTAT-GC pid mc Mu. to view other uses in the process: The RS occupancy in top is minus the footprint in the jmap-heap. /proc/$PID/maps Smaps is a more detailed informat

while the program is running.Local method Stacks: The local method stack plays a very similar role to the virtual machine stack, the virtual machine stack performs Java method services for the virtual machine, and the local method stack is a Native method service for virtual machines, which has no mandatory specification for the local method stack, and the virtual machines are free to implement him. The local method stack also throws Stackoverflowerr

Stacking Sort (Heapsort) is a sort algorithm designed using the data structure of a stacked tree (heap), which can quickly locate the elements of the specified index using the characteristics of the array. Heap ordering is an unstable sorting method, the auxiliary space is O (1), the worst time complexity is O (nlog2n), and the average performance of heap sequenc

Java divides memory into two types: one is stack memory and the other is heap memory. Some of the basic types of variables and object reference variables defined in a function are allocated in the stack memory of the function. When a variable is defined in a block of code, Java allocates memory space for the variable in the stack, and when the scope of the variab
