i want know whether other programming languages/platforms php, ruby, c# etc. (where dont have manually deal memory-managment) have same prolem gc java on jvm results in long pause, high response time, low throughput etc. on large heap size (> 5gb)? or that's general problem languages/platforms gc-ability, in java-world hot discussion thema because there many large scale systems written in java out there , 1 oftener have deal problem elsewhere? thx much! yes, gc-based languages have similar issues large heaps. has little language, , vm implementation (as gc tuning options , of course application code). since applications large heaps still quite rare becoming more common, becoming major selling point vendors of alternative vm implementations, such ibm or azul systems .

yeah, noob question of century... in seriousness, have no idea float value is... , more importantly, difference between float , integer. thanks in advance! see http://steve.hollasch.net/cgindex/coding/ieeefloat.html http://en.wikipedia.org/wiki/ieee_754-2008 basically, floating point data type way of storing numeric value in scientific notation. might write 2.3789 x 10^12, since computers work in binary, it's binary scientific notation. floating point values, in software, trade magnitude absolute precision (you've got many bits spread around). integers are...well..integers. rightmost (low-order bit) represents 2^0 (e.g., 1), next bit represents 2^1 (2s), next 2^2 (4) , forth. leftmost (high-order) bit represents sign (0 positive, 1 negative). brings negative values: represented in what's called two's-complement notation. two's complement of positive number: flip bits: zeros become ones , ones become zeros. add 1 result, doing usual ca...
