The difference between final, finally and finalize in java

The difference is as follows:

final: Modifier (keyword), used to declare attributes, methods and classes, respectively indicating that attributes are immutable, methods cannot be overridden, and classes Not inheritable.

Therefore a class cannot be declared both abstract and final. Declare variables or methods as final to ensure that they will not be changed during use. Variables declared as final must be given an initial value when declared (lazy initialization can also be used), and can only be read in subsequent references and cannot be modified. Methods declared as final can also only be used and cannot be overloaded.

finally: It is part of the exception handling statement structure, indicating that it is always executed.

finalize: It is a method of the Object class. Java technology allows the use of the finalize() method to do necessary cleanup work before the garbage collector clears the object from the memory. This method can be overridden to provide garbage collection. For other resource recycling, such as closing files, etc., the JVM does not guarantee that this method will always be called.
