I have an applet that opens a class I derived from the frame class, and which is a form to enter user input to query a Database. When the frame closes, I need to call a couple of the Applets methods(repaint). Using Java 1.01, I've found that I need to spawn a new thread and make my frame-derived class implement the runnable interface. How should I kill the thread and how can I get the applet to know that the thread has been killed?
You know that there are two ways to create a thread. By extending the Thread class and overriding its run() method, or by creating a new Thread object, that has as target a class that implements
Our Dev teams are like yours. They’re continually cranking out code for new features/bugs fixes, testing, deploying, testing some more, responding to production monitoring events and more. It’s complex. So, we thought you’d like to see what’s working for us.
Java can be integrated with native programs using an interface called JNI(Java Native Interface). Native programs are programs which can directly run on the processor. JNI is simply a naming and calling convention so that the JVM (Java…

Viewers learn about the scanner class in this video and are introduced to receiving user input for their programs. Additionally, objects, conditional statements, and loops are used to help reinforce the concepts.
Introduce Scanner class:
Viewers will learn one way to get user input in Java.
Introduce the Scanner object:
Declare the variable that stores the user input:
An example prompting the user for input:
Methods you need to invoke in order to properly get user input:
