JDBC - Statements, PreparedStatement and CallableStatement A simple call to the close() method will do the job. If you close the Connection object first, it will close the PreparedStatement object as well. However, you should always explicitly close the PreparedStatement object to ensure proper cleanup. For a better understanding, let us study Prepare-Example Code.

Boolean Structure For example, in the String.Compare(String, String, Boolean) method, the final parameter, ignoreCase, is a flag that indicates whether the comparison of two strings is case-insensitive (ignoreCase is true) or case-sensitive (ignoreCase is false). The value of the flag can then be evaluated in a conditional statement.

Application.Run Method  () Run is called to start a WPF application. If you define your Application using markup, or markup and code-behind, Run will be called implicitly. However, if you define your Application using code, you will need to explicitly call Run. When Run is called, Application attaches a new Dispatcher instance to the UI thread. Next, the Dispatcher object's Run method is called, which starts a message pump to process windows messages. Finally, the Dispatcher object calls the Application object's the OnStartup method to raise the Startup event.

Wildcard Capture and Helper Methods . When the. method invokes List.set(int, E) , the compiler is not able to confirm the type of object that is being inserted into the list, and an error is produced. When this type of error occurs it typically means that the compiler believes that you are assigning the wrong type to a variable.

Java Method Arguments When Java calls a method, it makes a copy of its actual parameters and sends the copies to the method where they become the formal parameters. Then when the method returns, those copies are discarded and the variables in the main code are the same as before.

CloseHandle (Windows CE 5.0) Use CloseHandle to close handles returned by calls to the CreateFile function. Use FindClose to close handles returned by calls to the FindFirstFile function. When an application running in user mode calls CloseHandle, the kernel calls internal functions that clean up any associated resources, such as MyFileSystem_PreCloseHandle and MyFileSystem_CloseHandle.

Basic try-catch-finally Exception Handling in Java If an exception is thrown from the reader.read() method then program execution is halted, and the exception is passed up the call stack to the method that called openFile(). If the calling method has a try-catch block, the exception will be caught there. If the calling method also just throws the method on, the calling method is also interrupted at the openFile() method call, and the exception passed on up the call stack.

The equals () Method example in Java The equals() Method example in Java. By: Baski Emailed: 1670 times Printed: 2144 times. The equals() method compares two objects for equality and returns true if they are equal. The equals() method provided in the Object class uses the identity operator (==) to determine whether two objects are equal. For primitive data types, this gives the correct result. For objects, however, it does not.

Exception Class A caller then calls FindOccurrences twice. In the second call to FindOccurrences, the caller passes a null as the search string, which cases the String.IndexOf(String, Int32) method to throw an ArgumentNullException exception. This exception is handled by the FindOccurrences method and passed back to the caller.

Method Overloading in Java In java, method overloading is not possible by changing the return type of the method because there may occur ambiguity. Let's see how ambiguity may occur: because there was problem: int result=obj.sum(20,20); //Here how can java determine which sum() method should be called.

Returning a Value from a Method It does not need to contain a return statement, but it may do so. If you try to return a value from a method that is declared void, you will get a compiler error. The data type of the return value must match the method's declared return type; you can't return an integer value from a method declared to return a boolean.

TRY...CATCH (Transact-SQL) If the stored procedure does not contain its own TRY…CATCH construct, the error returns control to the CATCH block associated with the TRY block that contains the EXECUTE statement. If the stored procedure contains a TRY…CATCH construct, the error transfers control to the CATCH block in the stored procedure.When the CATCH block code finishes, control is passed back to the statement immediately after the EXECUTE statement that called the stored procedure.f the stored procedure does not contain its own TRY…CATCH construct, the error returns control to the CATCH block associated with the TRY block that contains the EXECUTE statement. If the stored procedure contains a TRY…CATCH construct, the error transfers control to the CATCH block in the stored procedure.

The (often non-) difference between Close and Dispose What is the difference between Close and Dispose? In most .NET framework classes, there is no difference between Close() and Dispose(). For example, these methods do the same thing in the System.IO.Stream hierarchy, and it doesn’t matter which of the two methods you call. You should call one but not both.
