Return statement in finally block in java

Can we write return statement in finally block

• Finally block will executes always excepts system.exit().
• So if we are returning some value in finally means it will be returned always
• Finally will executed so method always returns finally return value and no need of keeping return value at end of the method.
• And in finally after return if we keep some statement those statement will be treated as dead code.

i)Return statement in finally block

1. package com.exceptionhandlingiinterviewquestions;
2.  
3. public class TryCatchReturn{
4.  
5. int calc(){ 
6.         
7. try {
8.  
9. 
   
10.  
11. } catch (Exception e) {
12.  
13. }
14.  finally(){
15.  return 1;
16. }   
17.  System.out.println("End of the method"); // Error : Unreachable code
18. }
19.     
20.     
21. public static void main(String[] args) {
22.         
23.         TryCatchReturn obj = new TryCatchReturn();
24.        
25.  
26. }
27. 
    
28. }
     

ii) return statement in finally

1. package com.exceptionhandlingiinterviewquestions;
2.  
3. public class TryCatchReturn{
4.  
5. int calc(){ 
6.         
7. try {
8.  
9. 
   
10.  
11. } catch (Exception e) {
12.  
13. }
14.  finally(){
15.  return 1;
16. System.out.println("End of the method"); // Error : Unreachable code
17. }   
18.  
19. }
20.     
21.     
22. public static void main(String[] args) {
23.         
24.         TryCatchReturn obj = new TryCatchReturn();
25.        
26.  
27. }
28. 
    
29. }
     

iii) return statement in try catch and finally blocks

1. package com.exceptionhandlingiinterviewquestions;
2.  
3. public class TryCatchReturn{
4.  
5. int calc(){ 
6.         
7. try {
8.  
9. return 10;
10.  
11. } catch (Exception e) {
12.  return 20;
13. }
14.  finally(){
15.  return 30;
17. }   
18.  
19. }
20.     
21.     
22. public static void main(String[] args) {
23.         
24.  TryCatchReturn obj = new TryCatchReturn();
25.        
26.  System.out.println(obj.calc())
27. }
28. 
    
29. }

Output:

1. 30
