try (FileReader fr = new FileReader (path); BufferedReader br = new BufferedReader (fr)) {// Normal execution path.} catch (IOException ioe) {// Deal with exception.} // Resources in the try statement are automatically closed afterwards. finally {// A finally clause can be included, and will run after the resources in the try statements are ...
In computer programming, several language mechanisms exist for exception handling. The term exception is typically used to denote a data structure storing information about an exceptional condition. One mechanism to transfer control, or raise an exception, is known as a throw; the exception is said to be thrown. Execution is transferred to a catch.

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 the Java programming language, the try...catch block is used often to catch exceptions. All potentially dangerous code is placed inside the block and, if an exception occurred, is stopped, or caught.
catch Used in conjunction with a try block and an optional finally block. The statements in the catch block specify what to do if a specific type of exception is thrown by the try block. char Defines a character variable capable of holding any character of the java source file's character set. class
In this C# example, even though the code inside the try block throws an exception, it gets caught by the blanket catch clause. The exception has been swallowed and is considered handled, and the program continues.
In some languages multi-level breaks are also possible. For handling exceptional situations, specialized exception handling constructs were added, such as try/catch/finally in Java. The throw-catch exception handling mechanisms can also be easily abused to create non-transparent control structures, just like goto can be abused. [41]
