In this tutorial, we’ll demonstrate the use of the Apache POI, JExcel, and Fastexcel APIs for working with Excel spreadsheets. These libraries can be used to dynamically read, write and modify the content of an Excel spreadsheet and provide an effective way of integrating Microsoft Excel into...
In every OOP class you learn that everything is an object. While it is true in Java land, Python has a lightweight solution that works better in our case -namedtuple. A namedtuple is just like it sounds, a tuple where the fields have names. You use it like a class and it consumes ...
In some APIs, the AWS CDK uses JavaScript arrays or untyped objects as input to a method. (See, for example, AWS CodeBuild’s BuildSpec.fromObject() method.) In Java, these objects are represented as java.util.Map<String, Object>. In cases where the values are all strings, you can ...
A lot of a functionality can be added using PhoneGap plugin APIs in MyEclipse 2015. This tutorial covers the limited APIs that PhoneGap ships with, though many of the steps can be used for third party APIs as well. In this tutorial, you will learn how to: ...
void setTitle(String title); //setter StringProperty titleProperty(); //property access Technically, getters and setters are not required, and the Property value can be used all the time. The Property class has the following two important APIs—Observable and Binding....
Three names are associated with a Font object: its logical name, family name, and font face name: A Font object's logical name is a name mapped onto a physical font, which is one of the specific fonts available on the system. When specifying a Font in Java, use the font face name ...
In addition, Java SE provides you with the FontMetrics class, which enables you to obtain measurements of text rendered by a Font object such as the height of a line of text in the font. You can use this information to precisely position text in Java graphical applications. See Measuring Te...
APIs Contracts Objects interact with the outside world with the methods they expose. The actual implementation is not important to the programmer, or it also might be secret. A company might sell a library and it does not want to disclose the actual implementation. A programmer might call ama...
Excel APIs in Microsoft Graph affect the resource usage of multiple dependency services. The impact can vary between different requests: for example, you might expect that updating a short string in a single cell of a small workbook would consume fewer resources than adding a big table with comp...
if you are connecting to an external resource that is proprietary or does not expose standard J2EE APIs, you may need to use a JCA (Java Connector Architecture) adaptor and an Application View control rather than a Java control to connect to that resource. JCA adaptors and the Application Vie...
