java eofexception

The input and output streams in the Java I/O system provide a lot of convenience for us to develop, leveraging its strong encapsulation capabilities, which can be implemented in a variety of combinations. But Java provides a lot of input and output stream classes, in terms of concept and use a lot of similarities, so many developers have trouble, when should use what kind of input and output stream class be

serialization data. The second method is used to generate JAVA serialized data. The data format is as follows. When the JAVA serialization data generated in the first method is sent to weblogic, weblogic throws the following exception. Java. io. EOFException At weblogic. utils. io.

For example, Object x [] = new String [3]; x [0] = new Integer (0 ); 11, NegativeArraySizeException An error occurred while creating an array of negative values. For example, int [] arr = new int [10]; int I = arr [-1]; 12. SecurityException Security exception, for example, Android permission exception.

In Java I/O, all streams (including input and out streams) have two types: 1.1 byte-oriented stream, reads or writes information from or to the stream in bytes. Byte-oriented stream includes the following types: 1) input stream: 1) bytearrayinputstream:

clearJava defines the hierarchy of an exception class that begins with Throwable, expands the error and exception, and exception expands Runtimeexception.1.Figure 1. Java Exception hierarchyThese four classes are generalized and do not provide much error information, although instantiating these classes is syntactically legal (for example: New Throwable ()), but it is best to use them as virtual base classes, using their more specific subclasses.
