Object-oriented programming languages lack high-level support for platform-independent service interactions. In Java, for instance, the burden of guaranteeing sustainable interoperability is put entirely on the

If the PreparedStatement object returns automatically generated keys, call DB2PreparedStatement.getDBGeneratedKeys to retrieve an array of ResultSet objects that contains the automatically generated keys. Check the length of the returned array. If the length of the returned array is 0, an error occur...
A method and system of executing a system call in an object oriented programming language such as Java鈩 . At least some of the illustrative embodiments may be system and method of creating a first package comprising a first inaccessible method and a second package comprising a second method, ...
Objects are ussually created in the young area. Once an object has survived a couple of GC cycles it is tenured to the old generation. (The JRockit and IBM JVM make exceptions for very large objects, as I will explain later.) After the application has completed its initial startup phase...

By giving the compiler the hint you were expecting an override that lets the compiler catch the subtle bug that the equals() method takes an Object type parameter. Is the @Override annotation useful in the real world? Only if you're an ultra-disciplined programmer who's willing to mark eve...
Trying to deal with Java's mutable collections when they're used on what is supposed to be animmutableobject is usually a recipe for pain. Almost invariably, to do something as simple as adding an item to a list, you have to pull the list out of the POJO, make a copy, do the tran...
When you run the build or profile commands in Slim it gives you an opportunity to interact with the temporary container it creates. By default, it will pause and wait for your input before it continues its execution. You can change this behavior using the --continue-after flag. If your ap...
编译和汇编:In the second pass, thecode generatorwalks through theparse treeand generates either assembly language code or machine code for the nodes of the tree. 经过这两个过程以后会产生一个object(目标goal) module(通常以.o .obj结尾)。
