Kiniry writes that "As any Java programmer knows, the volume of try catch code in a typical Java application is sometimes larger than the comparable code necessary for explicit formal parameter and return value checking in other languages that do not have checked exceptions. In fact, the general consensus among in-the-trenches Java programmers ...
try-with-resources statements are a special type of try-catch-finally statements introduced as an implementation of the dispose pattern in Java SE 7. In a try-with-resources statement the try keyword is followed by initialization of one or more resources that are released automatically when the try block execution is finished. Resources must ...
In computing and computer programming, exception handling is the process of responding to the occurrence of exceptions – anomalous or exceptional conditions requiring special processing – during the execution of a program.
// Since the exception has not been given an identifier, it cannot be referenced.} catch {// Handles anything that might be thrown, including non-CLR exceptions.} finally {// Always run when leaving the try block (including catch clauses), regardless of whether any exceptions were thrown or whether they were handled.
Since JDK 1.2, Java has included a standard set of collection classes, the Java collections framework. Doug Lea, who also participated in the Java collections framework implementation, developed a concurrency package, comprising several concurrency primitives and a large battery of collection-related classes.

A class with a given name can only be loaded once by a given class loader. Each Java class must be loaded by a class loader. [3] [4] Furthermore, Java programs may make use of external libraries (that is, libraries written and provided by someone other than the author of the program) or they may be composed, at least in part, of a number of ...
A class declared as sealed via the keyword sealed in C# or final in Java or PHP. [38] [39] [40] For example, Java's String class is marked as final. [41] Sealed classes may allow a compiler to perform optimizations that are not available for classes that can be subclassed. [42]
The Java Class Library (JCL) is a set of dynamically loadable libraries that Java Virtual Machine (JVM) languages can call at run time. Because the Java Platform is not dependent on a specific operating system , applications cannot rely on any of the platform-native libraries.
