Java Screen Monitoring: Techniques & Tools

Java itself cannot directly achieve the function of monitoring the screen, but it can achieve this by calling the APIs provided by the operating system.

One common practice is to use Java to call the operating system’s screen capture tool to achieve screen monitoring functionality. For example, in Windows systems, Java can be used to call Windows’ GDI or DirectX API to take a screenshot, then analyze the content to monitor screen changes.

Another approach is to utilize third-party libraries such as the Java AWT and Java Swing libraries which offer APIs for handling graphical user interfaces. These APIs can be used to monitor elements on the screen like buttons and text boxes.

In general, Java itself cannot directly implement screen monitoring functionality and needs to rely on APIs provided by the operating system or third-party libraries to do so.
