Exception Handling in JAVA 11
Difference between final, finally and finalize
There are many differences between final, finally and finalize. A list of differences between final, finally and finalize are given below :
| final | finally | finalize |
| Final is used to apply restrictions on class, method and variable. Final class can't be inherited, final method can't be overridden and final variable value can't be changed. | Finally is used to place important code, it will be executed whether exception is handled or not. | Finalize is used to perform clean up processing just before object is garbage collected. |
| Final is a keyword. | Finally is a block. | Finalize is a method. |
| Example: class FinalExample{ public static void main(String[] args){ final int x=100; x=200;//Compile Time Error } } | Example: class FinallyExample{ public static void main(String[] args){ try{ int x=300; }catch(Exception e){System.out.println(e);} finally{System.out.println("finally block is executed");} } } | class FinalizeExample{ public void finalize(){System.out.println("finalize called");} public static void main(String[] args){ FinalizeExample f1=new FinalizeExample(); FinalizeExample f2=new FinalizeExample(); f1=null; f2=null; System.gc(); } } |
