When I try to get the private data member of Java, I am using getter and setter method. But some how it is not coming in the input. Below is my code. What mistake I am doing? Also please can you suggest improvisation of the code to standard.

package Constructors;

public class Constructor {
    
    
    //Bank HDFC has few fields to be declared  
    public String customerName;
    public int age;
    private long adharNumber;
    protected long accountNumber;
    protected double bankBalance;
    short birthDate;
    String birthMonth;
    int BirthYear;
    public short branchCode;
    public String IFSCCode;
    public String branchLocation;
    
    
    
    
    
    public Constructor(long accountNumber,int age)
    {
        this();//calling constructor should be the first statement
        this.accountNumber=accountNumber;
        this.age=age;
        System.out.println("Details of "+accountNumber+" are as follow:");
        
    }

    
    public Constructor() {
        this.customerName="Harish";
        this.adharNumber=12456789;
        this.bankBalance=1200.56;
        this.birthDate=20;
        this.birthMonth="OCT";
        this.BirthYear=1994;
        this.branchCode=20;
        this.IFSCCode="HDFC000003";
        this.branchLocation="Bengaluru";
    }


    public void getProtected()
    {
        System.out.println("bankBalance: "+this.bankBalance);
    }
    public void getPrivate(long adharNumber)
    {
        
        this.adharNumber=adharNumber;
        getAdharNumber();
        System.out.println("adharNumber :"+adharNumber);
        
    }
    public void getPublic()
    {
        System.out.println("customerName :"+customerName);
        System.out.println("branchCode :"+branchCode);
        System.out.println("IFSCCode :"+IFSCCode);
        System.out.println("branchLocation :"+branchLocation);
        
    }
    public void getDefault()
    {
        System.out.println("birthDate :"+birthDate);
        System.out.println("birthMonth :"+birthMonth);
        System.out.println("BirthYear :"+birthMonth);
    }

    public long getAdharNumber() 
    {
        
        return adharNumber;
    }
}

public class ConstructorTest {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        
        Constructor c=new Constructor(22334455,29);
        
        c.getPublic();
        c.getProtected();
        c.getDefault();
        c.getPrivate();

    }

}

Expected o/p:

Details of 22334455 are as follow:
customerName :Harish
branchCode :20
IFSCCode :HDFC000003
branchLocation :Bengaluru
bankBalance: 1200.56
birthDate :20
birthMonth :OCT
BirthYear :OCT
adharNumber :12456789

Actual o/p:

Details of 22334455 are as follow:
customerName :Harish
branchCode :20
IFSCCode :HDFC000003
branchLocation :Bengaluru
bankBalance: 1200.56
birthDate :20
birthMonth :OCT
BirthYear :OCT
adharNumber :0
