Forcing type conversions Basic data types Reference data type In Java, because of inheritance and upward transformation, subclasses can be converted very naturally to a parent class, but the parent class is converted to a subclass that requires casting. Because subclasses have more properties than the parent class and are more powerful, the parent class is forced to convert to subclasses. So, is it a success if the parent class is converted to a subclass? In fact, the forced ty

JAVA review 3 Java classes and objects I wrote two decommissioned articles, so I wrote something useful on my blog. If you want to learn JAVA, you must understand the relationship between classes and objects ,, because a major feature of JAVA is object-oriented .. Let's take a look at the concepts of classes and objects: (these concepts are annoying in school) Object: An object is an instance of a class

It belongs to the leak check.Java source files are compiled to generate a class file/bytecode file to help you achieve a truly cross-platform. A class is compiled into a class file. The execution is then interpreted through the JVM (the Java Virtual machine).Java of 8 a basic data type :Four integer types: Byte (1 bytes different and range different 2^7~2^7), short (2), int (4), Long (8)Two floating-point types: Float (4), double (8)Boolean type: Boolean (1)Character type: char (2)Java Specifica

choose to recover the directory. Dd command usageDd can also back up the file systemDd If = files_to_backup of = filename to back up files. Then, use dd If = filename of = files_to_backup to restore the file.The most powerful feature of the DD command is that the DD command can back up files directly at the block level. You can back up information such as MBR of a disk. For exampleDd If =/dev/sda1 of =/dev/sdb1 sdb1 is an unformatted partition, but after backup, sdb1 can be directly mounted
