Practical 3 Java

 Basic Program using Class

1. Create a class BankAccount that has Depositor name , Acc_no, Acc_type, Balance as Data Members and void createAcc() . void Deposit(), void withdraw() and void BalanceInquiry as Member Function. When a new Account is created assign next serial no as account number. Account number starts from 1

package com.company;

import java.util.Scanner;

public class bank {

    String depositorname;

    int Acc_no;

    String acc_type;

    double balance;

    static int flag=0;

    Scanner sc=new Scanner(System.in);

    bank()

    {

        createaccount();

    }

    void createaccount ()

    {

       Acc_no=++flag;

       System.out.println("enetr depositor name");

       depositorname=sc.nextLine();

        System.out.println("enter account type");

        acc_type=sc.nextLine();

        balance=sc.nextDouble();

    }

    void withdraw ()

    {

        System.out.println("enter how much amount you wat to withdraw");

        double ammount= sc.nextDouble();

        balance=balance-ammount;

        System.out.println(ammount+"is debited from your bank tremaining bakalnce is "+balance);

    }

    void deposite ()

    {

        System.out.println("enter how much amount you wat to deposite");

        double ammount= sc.nextDouble();

        balance=balance+ammount;

        System.out.println(ammount+"is credit from your bank remaning balance is "+balance);

    }

    void balanceinquiry ()

    {

        System.out.println(depositorname);

        System.out.println(Acc_no);

        System.out.println(acc_type);

        System.out.println(balance);

    }

}

public class Main {

    public static void main(String[] args) {

    bank b1=new bank();

    bank b2=new bank();

    bank b3=new bank();

    b1.withdraw();

    b1.balanceinquiry();

    b2.deposite();

    b2.balanceinquiry();

    b3.balanceinquiry();

    }

}

2. Create a class time that has hour, minute and second as data members. Create a parameterized constructor to initialize Time Objects. Create a member Function Time Sum (Time, Time) to sum two time objects.

package com.company;

public class TIME {

     int hour;

     int min;

     int sec;

    TIME(int hour,int min,int sec)

    {

        this.hour=hour;

        this.min=min;

        this.sec=sec;

    }

    TIME ()

    {}

    TIME sum2objects (TIME a)

    {

        TIME ret=new TIME();

        ret.hour=this.hour+a.hour;

        ret.min=this.min+a.min;

        ret.sec=this.sec+a.sec;

        if(ret.sec >59)

        {

            ret.min++;

            ret.sec-=60;

        }

        if(ret.min >59)

        {

            ret.hour++;

            ret.min-=60;

        }

        return ret;

    }

}

public class Main {

    public static void main(String[] args) {

    TIME t1=new TIME(4,34,56);

    TIME t2=new TIME(2,30,59);

    TIME t3=t2.sum2objects(t1);

    System.out.println(t3.hour+" : "+t3.min +" : "+ t3.sec);

    }

}

3. Define a class with the Name, Basic salary and dearness allowance as data members.Calculate and print the Name, Basic salary(yearly), dearness allowance and tax deduced at source(TDS) and net salary, where TDS is charged on gross salary which is basic salary + dearness allowance and TDS rate is as per following table

DA is 74% of Basic Salary for all. Use appropriate member function

package com.company;

public class salary {

    String name;

    double salary;

    double dearnessallowance;

    salary (String name,int salary)

    {

        this.name=name;

        this.salary=salary;

        this.dearnessallowance=0.74*salary;

    }

    double tds () {

        if (salary + dearnessallowance <= 100000) {

            return 0;

        } else {

            return salary + dearnessallowance * 0.10;

        }

    }

        void printeverything ()

        {

            System.out.println("name: "+name);

            System.out.println("basic salary: "+salary);

            System.out.println("tds: "+tds());

            System.out.println("dearness allowance: "+dearnessallowance);

            System.out.println("net salary: "+ (salary+dearnessallowance-tds()));

        }

    }

public class Main {

    public static void main(String[] args)

    {

        salary s=new salary("vedantraval" ,2500000);

        s.printeverything();

    }

}
