how to fix java virtual machine launcher error

Structure of class fileThere are two structures in Java's class file: unsigned numbers and tables. The smallest storage unit is 8 bytes.Unsigned numbers are the basic data types used to describe numbers, UTF-8 encoded strings, and index references.Represents a complex data structure that consists of multiple unsigned numbers.which Magic is the magic number, and the magic number takes up 4 bytes, what is the magic number to do? It actually means that the type of the file is a class file, no

representing N to the Class D loader to load the class C. In the loading process, because there is no data verification, bytecode verification is required, it may trigger loading of other related classes, such as loading the parent class of this class or the implemented interface. Once any exception occurs during the loading process, the parsing process will fail.B. if C is an array type and the element type of the array is an object, that is, the N descriptor will be similar to "[Ljava. lang.
