  • When do you need to use malloc()? my code always seems to work without it.
    Previous to these pathetic series of lies that you call comments were created I've seen the source code to various JVMs and they all use malloc. Hotspot (The JVM) even has an entire class dedicated to tracking malloc. (tbh most large C / C++ projects wrap malloc like that)

    See the commit for yourself! They removed the sharing between string values when you created a substring a while ago.

  • Why can Strings use .equals and == but ints can only use ==?
    In many languages, like C++ or C# or Python, you can change the behavior of == to tell you if two objects are equivalent but you can't do that in Java. Instead, you define a method public boolean equals(Object other) that can use custom logic to check if two objects are equivalent. You can see this method defined for String in the Java source code here. But since primitives don't have methods, you can't do that for int or bool so you're stuck using two different comparison methods depending on the type you're comparing.

  • I found my new favorite way to create Swing apps
    reddit.com/r/java | 2021-01-18
    For performance reasons a component is not dynamically updated on each single change. It needs to be explicitly told. Usually done with either SwingUtilities.updateComponentTreeUI(frame) or invalidate(), validate() and repaint(). setVisible(true) does something similar internally.
