Finally Block In Java

Finally block always execute after try catch block.

1.
 package exception_handling;

public class FinallyBlock {
           
public static void main(String[] args) {
try {
int i=10/0;
} catch (Exception e) {
System.out.println(e);
}
finally{
System.out.println("You Are In Finally Block");
}
}
}

Output:

java.lang.ArithmeticException: / by zero

You Are In Finally Block

2.

package exception_handling;

public class FinallyBlock {

            

public static void main(String[] args) {

try {

int i=10/10;

} catch (Exception e) {

System.out.println(e);

}

finally{

System.out.println("You Are In Finally Block");

}

}

}

Output:

You Are In Finally Block

3. If You Use Return Statement in try /catch block then finally always execute  

package exception_handling;

public class FinallyReturn {

int display(){

try {

System.out.println("In display try"); 

return 2;

} catch (Exception e) {

System.out.println(e);

}finally{

System.out.println("Hi Finally Here");

}

return 1;

}

public static void main(String[] args) {

FinallyReturn finallyReturn=new FinallyReturn();

finallyReturn.display();

}

}

Output:

In display try

Hi Finally Here

4. If we use exit(0) in  try block then finally block will not execute.

package exception_handling;

public class FinallyExit {

public static void main(String[] args) {

try {

System.out.println("welcome Dear");

System.exit(0);

} catch (Exception e) {

System.out.println(e);

}finally{

System.out.println("Welcome In Finally Block");

}

}

}

Output:

welcome Dear
