Java desktop development is not dead — it just got more confusing. In 2026 you have three credible paths to a native desktop app: Swing, the 1997-era toolkit that still ships inside every JDK; JavaFX, the modern retained-mode framework that Oracle handed to the OpenJFX community; and Compose Multiplatform, JetBrains’ declarative UI that compiles the same Kotlin code to Windows, macOS, Linux, Android, and iOS.
