Java: Loading Large Data into JTable or JList
In software programming (especially Graphical User Interface or GUI programming), many times, we need to load data from file or database into a table or list to be displayed to user on computer screen. Most of the time, the size of the data can be determined only during runtime. The data could be very small to a few rows of record and could be very large to a few millions rows of record.
Java: Least Recently Used (LRU) Cache
Least Recently Used or in short LRU is an performance optimizing algorithm. LRU algorithm is widely used in software programming as well as in hardware instructions (e.g. CPU).
In many case, in programming, we may want to cache some data from physical disk, for example database and files, but we cannot load all the data into memory due to the memory limitation on the server or PC. In those cases, you may want to consider to use LRU algorithm to solve the memory limitation problem.
