Budget Tracker using Java With Source Code
Introduction :
The above code is a sample implementation of a budget tracker in Java. The BudgetTracker class keeps track of a user’s expenses and incomes, and calculates the current budget balance.
The class has a constructor BudgetTracker(), which initializes two ArrayList objects, one for expenses and one for incomes, as well as a double variable balance which is set to zero.
The class has three methods:
addExpense(double expense): This method takes in a double value as an argument, representing an expense, and adds it to the expensesArrayList. It also subtracts the expense from the balance.addIncome(double income): This method takes in a double value as an argument, representing an income, and adds it to the incomesArrayList. It also adds the income to the balance.getBalance(): This method returns the current balanceprintExpenses(): This method prints out all the expenses stored in the expensesArrayListprintIncomes(): This method prints out all the incomes stored in the incomesArrayList
It’s worth noting that this is just a basic example, and you might want to add more features such as handling categories, displaying the balance in a specific currency,
