Finally block in Java, Easy To Learn Finally block Tutorial in Java

Java Finally block

Finally block :

1) finally is a block it is always executed irrespective of try and catch.

2) Finally contains clean-up code.

3) It is not possible to write finally alone . we must take try-catch-finally otherwise take the try-finally these two are the possibilities. If we are taking any other we are getting compilation error saying finally without try block .

Syntax:-
try
{
risky code;
}
catch (Exception obj)
{
handling code;
}
finally
{
free code;
}

Exception raised in try block and corresponding catch block is matched then rest of the code is executed normally.

class Test 
{ 
public static void main(String[] args) 
{ 
try 
{ 
System.out.println(10/0); 
} 
catch (ArithmeticException ae) 
{ 
System.out.println("u r getting ae:"+ae);
} 
finally 
{ 
System.out.println("finally block is always executed"); 
} 
System.out.println("rest of the code"); 
} 
}

Output :

output:U r getting ae:ArithmeticException : /by zero Finally block is always executed

with out Exception finally block is executed

class Test 
{
public static void main(String[] args) 
{ 
try 
{ 
System.out.println("freetimelearn"); 
} 
finally 
{ 
System.out.println("finally block"); 
} 
} 
};

Output :

freetimelearn finally block
