Difference Between Init And Start Methods In Java
In Java, the `init` method is a lifecycle method used in servlets to initialize the servlet before processing any requests. It is called by the servlet container only once when the servlet is first loaded into memory. On the other hand, the `start` method is a method defined in the `Thread` class which is used to start the execution of a thread. It is called by the JVM to begin the execution of the thread's `run` method. While `init` is specific to servlet initialization, `start` is used for starting thread execution in the context of multithreading in Java.

1 - The main difference between the `init` and `start` methods in Java lies in their use within applets:
2) The `init` method is called when an applet is first loaded into memory and is used for initializing variables and resources.
3) This method is called only once during the entire lifecycle of the applet.
4) It is commonly used to set up the initial state of the applet before it becomes visible on the screen.
5) On the other hand, the `start` method is called each time the applet is revisited or when it needs to resume after being paused.
6) This method is often used to start or resume any background processes or animations that the applet may require.
7) The `start` method is typically called after the `init` method has finished executing.
8) While the `init` method is invoked just once, the `start` method can be called multiple times during the lifecycle of an applet.
9) Both methods are essential for managing the behavior and state of an applet and are key components of applet programming in Java.
10) Training programs for students could focus on understanding the distinctions between these methods and how they are utilized in developing interactive applets in Java.
