Hi,
I want to write a code to transfer amount from one account to another.
A table will store the amount corresponding to each.

Suppose this how i transfer amount of 10  from account named A to account B

boolean amountToAdd(changeBy, accountName ) {
I run the following query using jdbctemplate with autocommit = 0
update account
set amount = amount +changeBy
where name = accountName
}

Now in my java code i will have the above mentioned transaction like :

Boolean isdeducted = amountToAdd(-10, A);
 Boolean isAdded = amountToAdd(10, B);

if(isdeducted && isAdded) {
    perform commit on transaction;
} else {
    perform rollback;
}
The issue comes in case of multithreading.
Suppose two such transactions are in process.

transfer 10 from A to B and transfer 10 from B to A

suppose amount in A = 100 and B = 90 to begin with
T1
A = A - 10  = 90
T2
B = B-10 = 80

Now as T1 has locked table A and T2 has locked Table B what will happen in this case ??

Also there is a possibility the T1 and T2 are getting executed over the same connection to the mysql server.
Then there could be the case like :

T1
A = A- 10 = 90
T2
B = B-10 = 80
A = A+ 10 = 100 (the changes will be visible as we are on the same connection)
commit;
so now A = 100 and B = 80
But suppose now there is a failure in db or something due to which T1 couldnt proceed
Then what will the value of A will it remain 100 or will it be rollbacked to what it was before T1 began...
