A graphics library is a program library designed to aid in rendering computer graphics to a monitor. This typically involves providing optimized versions of functions that handle common rendering tasks. This can be done purely in software and running on the CPU, common in embedded systems, or being...

and Netscape announced their intention to combine IFC with other technologies to form the Java Foundation Classes
Java Foundation Classes
The Java Foundation Classes are a graphical framework for building portable Java-based graphical user interfaces . JFC consists of the Abstract Window Toolkit , Swing and Java 2D. Together, they provide a consistent user interface for Java programs, regardless whether the underlying user interface...

Ultimately, Sun merged the IFC with other technologies under the name "Swing", adding the capability for a pluggable look and feel

In software design, look and feel is a term used in respect of a graphical user interface and comprises aspects of its design, including elements such as colors, shapes, layout, and typefaces , as well as the behavior of dynamic elements such as buttons, boxes, and menus...

Java is a programming language originally developed by James Gosling at Sun Microsystems and released in 1995 as a core component of Sun Microsystems' Java platform. The language derives much of its syntax from C and C++ but has a simpler object model and fewer low-level facilities...
Layout managers are software components used in widget toolkits which have the ability to lay out widgets by their relative positions without using distance units. It is often more natural to define component layouts in this manner than to define their position in pixels or common distance units,...

However, Swing also improved IFC in a lot of ways:
Model–view–controller is a software architecture, currently considered an architectural pattern used in software engineering. The pattern isolates "domain logic" from the user interface , permitting independent development, testing and maintenance of each .Model View Controller...

IFC components were not JavaBeans. IFC had a specific persistence mechanism, but it was a bit complex, and not compatible with the Java Serialization
