Starting another activity, either within your app or from another app, does not have to be a one-way operation. You can also start another activity and receive a result. For example, your app can start a camera app and receive the picture taken as a result. You can also start the Contacts App for the user to select a contact, and you will receive the corresponding details as a result.
When you start an activity to get a result, it is possible (and almost certain in the case of memory-intensive operations, such as using the camera) that your process and activity will be destroyed due to low memory.
For this reason, the Activity Result APIs separate the result callback from the place in the code where you initiate the other activity. Since the result callback must be available when the process and activity are recreated, the callback must be unconditionally registered each time your activity is created, even if the logic of starting the other activity only occurs with user input or other business logic.
How to force the exit of a for Java?
In java there are two statements that allow us to force the exit of a loop, and these statements are break (to completely exit the loop) and continue (to exit the current iteration and jump directly to the next one).
How to solve the Java Lang NullPointerException problem?
When all of a user’s resources are deleted via the edit user page, a java. lang. NullPointerException (ID-4811). To work around this problem, use the delete user page to delete or unlink these user resource accounts.
How to catch NullPointerException?
If you suspect that the variable has a null and will give a NullPointerException error, resolve it by adding a try-catch block and it will recover the error. You can give your objects a new Object and it will upload the null as a string to your application so you can see which object is the one that breaks the flow of your program.

Note also the root value of the repository:///Applications/FormsApplication/1.0/FormsFolder/ content is passed to OutputClient of the generatePDFOutput2 object (the second parameter). This value is passed to the Output service to inform the Output service that collateral material, such as images, is stored in this location.
The following Java code example sends a PostScript print stream to a network printer named Printer1. Two copies are sent to the printer. (See Sending print streams to printers).
The following Java code sample transforms an interactive PDF document named Loan.pdf to a non-interactive PDF document named NonInteractiveLoan.pdf. (See Docking PDF documents.)
A date and time formatted string defines the text representation of a DateTime or DateTimeOffset value that is the result of a formatting operation. It can also define the representation of a date and time value that is needed in a parse operation to correctly convert the string to a date and time. A custom format string consists of one or more custom date and time format specifiers. A string that is not a standard date and time format string is interpreted as a custom date and time format string.
You can download the Format Utility, which is a .NET Core Windows Forms application that allows you to apply format strings to numeric or date and time values, and displays the result string. The source code is available for C# and Visual Basic.
Some of the C# examples in this article run in the Try.NET inline code runner and playground. Click the Run button to run an example in an interactive window. Once the code is run, you can modify and run the modified code by clicking Run again. The modified code is executed in the interactive window or, if an error occurs in the compilation, all error messages from the C# compiler are displayed in the interactive window.
The IDE simplifies the development of web, enterprise, desktop and mobile applications using the Java and HTML5 platforms. In addition, it offers support for PHP and C/C++ application development.
With its comprehensive application development features, constantly improving Java Editor, and continuous speed and performance enhancements, NetBeans IDE sets the pace for application development with out-of-the-box novel technologies.
“At Liquid Robotics, our use of NetBeans IDE is all about integration. There’s the seamless integration of development tools and Java technologies within NetBeans IDE, but it’s also great for integrating external features, for example, Jenkins, which we use for our build server, Git (through GitBlit), which is our source code repository, JIRA for bug tracking, Maven for running builds, and Artifactory for maintaining artifacts created from builds. Then, there’s the code we’re writing: we have our own cloud data repository, a bunch of web apps, some Java desktop apps, and code running on the robot that uses the JDK 7 embedded ARM virtual machine. Being able to debug and monitor performance directly on an embedded device is very important. I was one of the first to incorporate NetBeans IDE 7.3, which introduced this feature, just because of its support for embedded profiling.”
