code errors - need some input.

[XodoX]

Hi.

The following code snippets got some errors in there, Netbeans says. Can somebody tell me what, and why, so that I understand the errors, please?

Database.Java

The first "private person" gives me an error. Why is that?

package Test;

public class Database {

    private person[] list;
    private int numberOfRecords;

    public Database() {
        
        throw new RuntimeException("Compiled Code");
    }

    public void add(String lastName, String firstName, int month, int day, int year) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public int find(String firstName, String lastName, int month, int day, int year) {
        
        throw new RuntimeException("Compiled Code");
    }

    public void printList() {
     
        throw new RuntimeException("Compiled Code");
    }
}

Date.Java

gives me an error for exit(1); and return month==theOtherDate.month && day==theOtherDate.day && year==year; ??

ackage Test;

import java.language.*;

public class Date
{
    private int day;
    private int month;
    public int year;

    public Date(int m, int d, int y)
    {
        setDay(d);
        setMonth(y);
        setYear(y);
    }

    private int getDay()
    {
        return day;
    }
    public int getMonth()
    {
        return month;
    }
    public int getYear()
    {
        return month;
    }
    public void setDay(int d)
    {
        if( d>0 && d<=30) // assume there are 30 days in a month
        {
            day =d;
        }
        else
        {
            System.out.println("Improper user input. Day must be in [1,30]");
            exit(1);
        }
    }
    public void setMonth(int m)
    {
        if( m>=1 && m<=12)
        {
            month =m;
        }
        else
        {
            System.out.println("Improper user input. Month must be in [1,12]");
            System.exit(1);
        }
    }
    public void setYear(int y)
    {
        if( y>1900 && y<2050)
        {
            year =y;
        }
        else
        {
            System.out.println("Improper user input. Year must be in [1901,2049]");
            System.exit(1);
        }
    }

    public int equals(Date theOtherDate)
    {
        return month==theOtherDate.month && day==theOtherDate.day && year==year;
    }
    public String toString()
    {
        return month + "/" + day + "/" + year;
    }
}

Person.Java

This gives me an error for the first 3 private strings ( firstname, lastname, birthdate) Any ideas?

package assignment2;

class Person {

    private string firstName;
    private string lastName;
    private Date birthDate;

    public Person(String fN, String lN, int month, int day, int year) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public boolean equals(Person theOtherPerson) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public boolean equal(String fN, String lN, int month, int day, int year) {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }

    public String toString() {
        //compiled code
        throw new RuntimeException("Compiled Code");
    }
}

I appreciate your help!
