When you do not use
The principle proposed in the previous article is to avoid creating unnecessary objects. For objects that occupy a large amount of resources, you can create them during program initialization and keep using them. Static constants can be used for
Object priority in Eden allocation
In most cases, objects are assigned preferentially in the new Generation Eden region. When the Eden memory area does not have enough space to allocate, the virtual machine triggers a Minor GC (the Cenozoic GC).
In Java, the For-each Loop simplifies the traversal of any collection or array, but not every Java programmer understands some of the details of the For-each loop that this article will describe. Other terms released with Java5: releasing alias
