Use the top command to dynamically monitor the memory usage of programs that run for a short period of time. Solution: Top-d 0.01-N2000-B | grep lzma -D specifies the interval at which top data is collected. The value is 0.01 seconds. -N indicates the total number of statistics. Set this parameter to 2000 to ensure that the top node does not end the stati

One of the best known advantages of Java technology is that, unlike other languages such as C programmers, Java programmers do not have to be responsible for daunting memory allocations and releases. The Java runtime can manage these tasks for you. Each instantiated object automatically allocates memory in the heap, and the garbage collector periodically reclaims the me
