Two types of computer programming 1. process-oriented model-linear execution is characteristic, and code is considered to act on data. 2. object-oriented model-organizes programs around its data (that is, objects) and the interfaces defined for this data.

If you don't want to read them, you can grasp the focus directly. I will change the color to indicate the focus! English is one of the most important ways for people to communicate with each other.

Why do I need an exception? In the past, when writing data structures in C, there is always such a worry: for example, the pop function of the stack, in addition to the function body to complete the operation of the stack, but also to use a return value, indicating whether the stack operation is successful.However, in order to return the value of the stack to the caller, it is necessary to use the return statement. But return is occupied by the function state value, so can only use pointers, thi

exception refers to the various conditions, such as: file cannot be found, network connection failure, illegal parameters and so on.An exception is an event that interferes with the normal instruction flow during the program's run.Java describes various kinds of exceptions through the many subclasses of the Throwable class in the API. Thus,Java exceptions are objects, examples of throwable subclasses , and describe error conditions that occur in a pie

be advertised as long as throw is included. If a method must handle multiple exceptions at the same time, all exceptions must be indicated in the header. As shown in the following example, use commas to separate them: 1234567 Class Animation { Public Image loadImage (Strint s) throws EOFException, MalformedURLException { ...... } } However, we do not need to advertise internal java errors or exceptions der

person who intends to use your own method: If you use this method, it can result in an abnormal generation (that is, using throws on the method head), a simple memory method:As long as there is a throw, you should notify throws. If a method must handle multiple exceptions at the same time, all exceptions must be indicated within the header.As shown in the following example, they are split with commas:1234567 class Animation {public Image LoadImage (strint s) throws

through code, and error rarely occurs. Therefore, programmers should focus on the various exception classes under the branch of the parent class exception.Exceptions: Exception and his subclasses represent a variety of unexpected events that are sent when the program is run. Can be used by the Java exception handling mechanism, which is the core of exception handling.Iv. Some common Java exception collatio

1. About serialization and deserialization We should all probably know the meaning of serialization and deserialization in Java, serialization is the conversion of a Java object into binary to transmit on disk or network stream, and deserialization means to reassemble the received binary stream into the original object inversion process. They are implemented in Java
