Heap space is a portion of memory dedicated to the runtime allocation of objects in Java. Every object that is created during the execution of a Java program is stored in the heap space. The heap space is managed by the Java Virtual Machine (JVM), which is responsible for allocating and deallocating memory for objects.

It is important to monitor the heap space usage of your Java applications to ensure that they do not run out of memory. If an application runs out of memory, it will crash and may result in data loss. There are a number of tools that can be used to check the heap space usage of a Java application, including the jconsole tool and the VisualVM tool.

Disk space is the amount of storage capacity available on a computer’s hard drive or other storage device. Checking disk space is important because it allows you to see how much space is left on your drive and helps you manage your storage effectively. If you run out of disk space, your computer may start to slow down or even crash.

There are several ways to check disk space on a PC. One way is to use the File Explorer window. To do this, open File Explorer and select “This PC” from the left-hand pane. The amount of free and used space on each drive will be displayed in the main window.

In Java, determining whether a string contains whitespace characters is a fundamental task for various text processing and validation scenarios. Whitespace characters include spaces, tabs, newlines, and other invisible characters that affect the layout and readability of text. Checking for whitespace helps ensure data integrity, improve code readability, and enhance user experience in applications.

The presence of whitespace can impact the logic and functionality of programs. For instance, when parsing user input or reading data from files, ignoring whitespace can lead to incorrect interpretations and errors. Additionally, whitespace can affect the appearance and alignment of text in user interfaces, impacting aesthetics and usability.
