Create a java class for Bank Accounts with these public String attributes: ownerName, acctNbr and these private double attribute

Readme [11.4K]

Answer:

public class BankAccounts

{

public String ownerName;

public String acctNbr;

private double debits;

private double credits;

public BankAccounts(String ownerNm, String acNum)

{

debits = 0;

credits = 0;

ownerName = ownerNm;

acctNbr = acNum;

}

public void addDebit(double debitAmt)

{

if(credits > (debits + debitAmt))

debits = debits + debitAmt;

else

System.out.println("Insufficient balance");

}

public void addCredit(double creditAmt)

{

credits = credits + creditAmt;

}

public double getBalance()

{

double balance = 0;

if((credits - debits) > 0) // return the value if there is actually some balance left.

balance = credits - debits;

return balance; //returns 0 if credits are lesser or equal to debits

}

Explanation:

Here class name is BankAccounts which can be used to create a new bank account whenever any user wants to open a bank account. This class will help to track any new account opening, debits and credits operations carried out on that account.

We have a constructor here, which accepts 2 arguments i.e. Bank account Owner Name and Account Number. The constructor also sets the values of debits and credits as 0.

The methods addDebit(), addCredit() and getBalance() help to perform Debit and Credit operations on the account.

NOTE: The method getBalance() returns a positive value only when credits are greater than debits.

The method addDebits() can add debits only as the condition that the credits are greater than the resultant debits.

The code for class BankAccounts is hereby attached.

The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word SET, followed by the name of the column to be updated, an equals sign, and the new value.

Explanation:

An Update Query is an action query (SQL statement) that changes a set of records according to criteria you specify.
The SQL UPDATE Query is used to modify the existing records in a table. You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected.
Update Queries let you modify the values of a field or fields in a table.

UPDATE Syntax 

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;

UPDATE table_name SET column1 = value1, column2 = value2, etc WHERE condition;

table_name: name of the table
column1: name of first , second, third column....
value1: new value for first, second, third column....
condition: condition to select the rows for which the
values of columns needs to be updated.
