Overly Long Class Names in Java or Geeky Poem?

In Java development, clear and concise naming conventions are essential for code readability and maintainability. However, sometimes, we stumble upon class names that stretch the limits of practicality. One such example is InternalFrameTitlePaneMaximizeButtonWindowNotFocusedState. But did you know that in Java 6, this class name was even longer?

Within the Java 6 JRE, there's a class with an astonishingly lengthy name:

com.sun.java.swing.plaf.nimbus.InternalFrameInternalFrameTitlePaneInternalFrameTitlePaneMaximizeButtonWindowNotFocusedState

This mouthful appears to be the product of a code generator that needed to be reviewed, leading to redundant and cumbersome naming. Or is it a geeky poem buried in the code?

InternalFrame InternalFrame
Title Pane,
Internal Frame 
Title Pane.

Maximize Button Window,
Not Focused State.

The moral of the story is always check the readability/sanity of generated code.
In this Hacker News Discussion another class was also considered homorously.

    There once was a generator vain,
    That repeated itself in a chain.
    “InternalFrame! Twice!
    TitlePane—also twice!”
    Now the class name is mostly refrain.

    Choir: InternalFrame! InternalFrame!
    Solo: TitlePane, make it grand!
    Choir: InternalFrame! TitlePane!
    Solo: Maximise at my command!
    All: Window not focused—state maintained—
    Audience: …and readability’s been strained

    Grant me, O JRE, the serenity
    to rename what I can,
    the courage to delete what I must,
    and the wisdom to stop the code generator
    after the second “InternalFrame”.

Demystifying Java Object Sizes: Compact Headers, Compressed Oops, and Beyond

Introduction Measuring an object’s size in Java is not straightforward. The platform encourages you to consider references and abstractions rather than raw memory usage. Still, understanding how objects fit into memory can yield significant benefits, especially for high-performance, low-latency systems. Over time, the JVM has introduced optimisations like Compressed Ordinary Object Pointers (Compressed Oops) and, more recently, Compact Object Headers. Each of these can influence how large or small your objects appear. Understanding these factors helps you reason about memory usage more concretely. Measuring Object Sizes In principle, you can estimate an object’s size by creating instances and observing changes in the JVM’s free memory. However, you must neutralise certain factors to get consistent results. For example, turning off TLAB allocation ( -XX:-UseTLAB ) makes memory usage more directly observable. Repeated measurements and median calculations can reduce the im...

Java is Very Fast, If You Don’t Create Many Objects

Image
  You still have to watch how many objects you create. This article looks at a benchmark passing events over TCP/IP at 4 billion events per minute using the net.openhft.chronicle.wire.channel package in Chronicle Wire and why we still avoid object allocations..  One of the key optimisations is creating almost no garbage. Allocation is a very cheap operation and collection of very short-lived objects is also very cheap. Does this really make a difference? What difference does one small object per event (44 bytes) make to the performance in a throughput test where GC pauses are amortised? While allocation is as efficient as possible, it doesn’t avoid the memory pressure on the L1/L2 caches of your CPUs and when many cores are busy, they are contending for memory in the shared L3 cache.  Results Benchmark on a Ryzen 5950X with Ubuntu 22.10. JVM Vendor, Version No objects Throughput, Average Latency* One object per event Throughput, Average Latency* Azul Zulu 1.8.0_322 60.6 ...
