final finally finalize in java
Final is used to apply restrictions on class, method, and variable.
The final class can't be inherited, final method can't be overridden,
and final variable value can't be changed. Final is a keyword
On the other hand
Finally is used to place important code, it will be executed
whether an exception is handled or not. Finally is a block
Lastly
Finalize is used to perform clean up processing just before an
object is garbage collected. Finalize is a method.what it means when create final variable in java
First of all, final is a non-access modifier applicable only to
a variable, a method or a class
When a variable is declared with final keyword, its value can’t be modified,
essentially, a constant. This also means that you must initialize a
final variable. If the final variable is a reference, this means that
the variable cannot be re-bound to reference another object, but internal
state of the object pointed by that reference variable can be changed
i.e. you can add or remove elements from final array or final collection.
It is good practice to represent final variables in all uppercase, using
underscore to separate words.what is final in java
Final is used to apply restrictions on class, method, and variable.
The final class can't be inherited, final method can't be overridden,
and final variable value can't be changed. Final is a keywordjava final meaning
private final String hello = "Hello World!";
/*
The keyword final states that the variable, method or class
associated will not have it's value changed.
*/final vs static keyword in java
The two really aren't similar.
"STATIC" fields are fields that do not
belong to any particular instance of a class.
and there is only one copy of the variable in memory
shared by all instances of the class.
On the other hand
"FINAL" The final keyword just means the value
can't be changed. Without final, any object can
change the value of the variableFinal keyword java
public class Main {
final int x = 10;
public static void main(String[] args) {
Main myObj = new Main();
myObj.x = 25; // will generate an error: cannot assign a value to a final variable
System.out.println(myObj.x);
}
