How would you handle exceptions in a multi threaded application?
- log it out in the method your new thread starts (top of the stack for the created thread) in.
- Use a construct like Asynchronous delegate, which will will return an exception when you call end invoke, which you can then catch in the normal way.
What is multi threading in Java Why do we require it?
The main purpose of multithreading is to provide simultaneous execution of two or more parts of a program to maximum utilize the CPU time. A multithreaded program contains two or more parts that can run concurrently.
What are some applications of using multiple threads?
Multiple threads of execution are used to load content, display animations, play a video, and so on. Another example of a multithreaded program that we are all familiar with is a word processor.
Why we use try catch in multithreading?
We simply placed a try/catch block around the start() method. After all, start() instantiates the secondary thread and calls its run() method and the use of try/catch is the natural way of dealing with exceptions. If the code in run() throws any exceptions we should be able to catch them.
How do you handle exceptions in multithreading in Java?
UncaughtExceptionHandler is an interface provided by Java to handle exceptions in a Thread run method. So we can implement this interface and set back our implementing class back to Thread object using setUncaughtExceptionHandler() method.
How can we achieve multithreading in Java?
Multithreading in Java
- Thread creation by extending the Thread class. We create a class that extends the java. lang. Thread class.
- Thread creation by implementing the Runnable Interface. We create a new class which implements java. lang. Runnable interface and override run() method.
- Thread Class vs Runnable Interface.
What is multithreading Java?
In Java, Multithreading refers to a process of executing two or more threads simultaneously for maximum utilization of the CPU. A thread in Java is a lightweight process requiring fewer resources to create and share the process resources.
Do I need multi threading?
You should use multithreading when you want to perform heavy operations without “blocking” the flow. Example in UIs where you do a heavy processing in a background thread but the UI is still active.
