Hi,
Consider the banking example. We know that there is a ledgerBalance(static) and it will be manipulated by every account holder when he/she does the transaction.
class Account{
private double myBalance;
public static double ledgerBalance;
public void withdraw(double amount){
if(myBalance > 0){
ledgerBalance = ledgerBalance-amount;
myBalance = myBalance - amount;
}
}
public void deposit(){
ledgerBalance = ledgerBalance+amount;
myBalance = myBalance +amount;
}
}
My question is how the ledgerBalance(which will be shared among all the A/C holders) will be changed at the same time Best Java if two or more user threads are doing the transaction at exactly same time.
What I am thinking that it is not possible to manipulate same variable by multiple threads at exactly same time. Anyone Knows the perfect answer? Please Help.
