Question

My values are not storing into my object and I keep returning zero. please explain my mistake thanks

public class CalanderDate {

int year = 0 ;
int day = 0;
int month= 0;
  
public static void main(String[] args) {
CalanderDate date;
date = new CalanderDate( 1, 10 ,1999);
System.out.print(date);
}
  
  
  

public CalanderDate(int month, int day , int year ) {
if (month < 1){
month = 1;
}
if (month> 12){
month = 12;
}
if (day < 1){
day = 1;
}
if (year < 1752){
year = 1752;
