市场上有很多好的 Java 编程书籍,但是对于一个刚接触 Java 并且只有很少编程知识的初学者来说,找到一本合适的并不容易。 这本书将帮助初学者学习如何有效地用 Java 编程。我的意图是简化 Java 更复杂的方面,并指导学习者探索“幕后”的东西我希望这本书里面的说明足够直观,读者可以通过实践来理解。 有编程经验的...

Type erasure also prohibits some other definitions, which would otherwise seem legal. In this code, we want to count the orders as represented in two slightly different data structures: // Won't compile interface OrderCounter { // Name maps to list of order numbers int totalOrders(Map<String...

Although this is a programming error of the offending application, this system property provides a solution to avoid the VM crash. With the property set to true (-Dsun.zip.disableMemoryMapping=true, or simply -Dsun.zip.disableMemoryMapping) the Sun JDK/JRE runtime disables the mmap usage ...
