In the Java Core Knowledge interview, you can always encounter questions about handling exception and error. Exception processing is a very important aspect of Java application development and the key to writing robust and stable Java programs, which naturally makes it a frequent part of the interview.

This is the first article that introduces the concept of error patterns, a very useful concept that will improve your ability to detect and correct errors in your code
Exceptions and errors:Exception:In Java, program errors are mainly syntax errors and semantic errors. Errors that occur during compilation and runtime of a program are collectively referred to as exceptions. They are VM (Virtual Machine) errors) one way to notify you, through which VM lets you know that you (developers) have made an error and now have a chance to modify it. In

Understanding final issues has important meanings. Many program vulnerabilities are based on this ---- final can only ensure that the reference always points to a fixed object, but cannot ensure that the state of that object remains unchanged. In multi-threaded operations, an object will be shared or modified by multiple threads. Unintentional modifications made by one thread to the object may cause another thread to cr

Many programmers do not realize that an error is different from an exception. When a problem occurs, this difference has important meaning for how to operate your code (see the tool bar, "Introduction error and e
