Regards By: Takeshi Ito garbage collection [ reply ]   2010-06-11 16:12 Hi, Is there any way we can trigger the JAVA garbage collector as soon as we want? The situation is: I get a JAVA ArrayList which contains a large amount of data, do some analysis on the data, and then get next data set of the same kind. The code looks like the following. > 100.times do |i| > j_array_list = java_function_that_get_data(i) > ## do some analysis here > end Since the data returned by 'java_funcion_that_get_data' is large, I want to free memory each time. Currently, however, the memory usase increases as each loop finishes. I tried the following, none of which worked: + j_array_list.clear + j_array_list = nil I am using rjb-1.2.1, Java-1.6.0-12, on CentOS, ruby-1.9.1p376. I appreciate any help from experts. Thank you.
