Garbage collection for Java Virtual Machines was never designed to automatically remove from memory objects that are exchanged between multiple instances. Java虚拟机的垃圾回收从来没有被设计成能自动清除在多实例间交换的内存对象。
Garbage can also be a good source for making building blocks, which are then covered with concrete. Now, more and more machines are designed for this purpose. 垃圾也是一种制造带有混凝土建筑砌块的好的原材料,现在,越大越多的机器为此意图而设计。
