Simple bank transaction details using basic OOP syntax in java ( Object Oriented programming)

Hi ALL,

Here I wrote a program for simple bank transaction details in based on the concept of  basic OOP syntax (Object Oriented programming) in java.

// Main class
public class bankApp {
    public static void main(String arg[]){
        bankAccountMaintance bam=new bankAccountMaintance(1000.00); //initializing values
        bam.displayAccountSummary(); //display balance
        bam.withdrawal(450.0); //make withdrawal
        bam.displayAccountSummary(); // display balance
        bam.Deposite(10000.0); // make deposit
        bam.displayAccountSummary(); //display balance
       
    }
}

// Sub class
class bankAccountMaintance{
    double balance;  // account balance
    public bankAccountMaintance(double opening_balance){  // constructor
        balance=opening_balance;
    }
    public void Deposite(double de_amt){ // makes deposit
        balance +=de_amt;
    }
    public void withdrawal(double wd_amt){ // makes withdrawal
        balance -=wd_amt;
    }
    public void displayAccountSummary(){ // displays balance
        System.out.println(" Balance amount is "+balance);
    }
}

OUTPUT

 Balance amount is 1000.0

 Balance amount is 550.0

 Balance amount is 10550.0
