Error trying to call parts of a class in a method Java

I am this close to finally completing this assignment, but I've hit a roadblock. For some reason I can't get call aspects of the class in my methods. Does anyone have a way of doing this that works? I've put comments next to the three parts I'm referring to. I do not know what is causing these errors, and Im grateful for any help.
public class Main
{
public static int w = -1;
public static int x = 0;
public static int y = 0;
public static int z = 0;
public static String[] names;
public static int[] years;
public static String[] studios;
public static class Movie{
// instance variables
private int year;
private String title;
private String studio;
private int placement;
// Constructor for objects of class Movie
Movie(String title, int year, String studio)
{
// initialize instance variables
this.title = title;
this.year = year;
this.studio = studio;
}
public String getTitle()
{
return title;
}
public void setTitle(String title)
{
this.title = title;
}
public void setPlacement() {
w+=1;
this.placement = w;
}
public int getPlacement() {
return placement;
}
public String getStudio()
{
return studio;
}
public void setStudio(String studio)
{
this.studio = studio;
}
public int getYear()
{
return year;
}
public void setYear(int year)
{
this.year = year;
}
public String toString()
{
String str = String.format("%-30s %4d %-20s", title, year, studio);
return str;
}
}
public static void arrNames(String name) {
x+=1;
names = new String[x];
names[(x-1)] = name.getTitle(); //error here, why can't I just use getTitle()?
}
public static void arrYear(String name) {
y+=1;
years = new int[y];
years[(y-1)] = name.getYear(); //same error
}
public static void arrStudio(String name) {
z+=1;
studios = new String[z];
studios[z-1] = name.getStudio(); //same error
}
public static void setGroup(String name) {
arrNames(name);
arrYear(name);
arrStudio(name);
}
public static void getGroups(String name) {
int a = x;
int b = y;
int c = z;
int d = 0;
int e = 0;
int f = 0;
System.out.println("Names Category: ");
while (a > 0) {
System.out.print(names[d] + " ");
d+=1;
a-=1;
}
System.out.println("Years Category: ");
while (b > 0) {
System.out.print(years[e] + " ");
e+=1;
b-=1;
}
System.out.println("Studios Category: ");
while (c > 0) {
System.out.print(studios[f] + " ");
f+=1;
c-=1;
}
public static void main(String[] args) {
Movie nemo = new Movie("Finding Nemo",2003,"Pixar");
setGroup(nemo.getTitle());
}
}

I will take this exemple:
public static void arrYear(String name) {
y+=1;
years = new int[y];
years[(y-1)] = name.getYear(); //same error
}
You are trying to use the method getYear on the variable name and the name is a String and not a Movie Object
You could just replace the argument from String to Movie like that:
public static void arrYear(Movie name) {
y+=1;
years = new int[y];
years[(y-1)] = name.getYear(); //same error
}
and it should work for all your functions

My java class validation is not working why?

If the quantity is not positive it should be set to 0.
If the price per item is not positive it should be set to 0.0.
Hwever when I enter a negative number it keeps setting my variable negative and not Zero.
This is my class package com.company;

public class Invoice {

//Main method
package com.company;
public class Main {
public static void main(String[] args) {
// write your code here
Invoice myTruck = new Invoice("A101", "Wheels", -2, 100.00);
System.out.println(myTruck.getPartDescription());
System.out.println(myTruck.getPartNumber());
System.out.println(myTruck.getPartQuantity());
System.out.println(myTruck.getPartPrice());
double price = myTruck.getPartPrice();
int quantity = myTruck.getPartQuantity();
System.out.println("The total cost is " + myTruck.invoiceAmountMethod(price, quantity));
}
}
OUTPUT
Wheels
A101
-2
100.0
The total cost is -200.0

You're assigning:
this.partQuantity = 0;
but you return:
return partPrice * partQuantity;
(the parameters that were passed to the method).
you can fix it by returning:
return this.partPrice * this.partQuantity;
and you really shouldn't pass any parameters to this method.

Here is what you need.
public double invoiceAmountMethod(double partPrice, int partQuantity) {
return (partQuantity < 0 || partPrice < 0.0)?0.0:partPrice * partQuantity;
}

First, you should not be using doubles for these number. It just accounts to inefficiency and makes no sense. However, when using ints, you have to note that you cannot directly get a percentage when dividing two ints. This piece of code should work, you may want to include some code that checks that the divisors are not 0.
private int freeThrowsAttempted;
private int freeThrowsMade;
private int twoPointFieldGoalsAttempted;
private int twoPointFieldGoalsMade;
private int threePointersAttempted;
private int threePointersMade;
...
double percentage1 = (twoPointFieldGoalsMade * 100F) / twoPointFieldGoalsAttempted;
double percentage2 = (threePointersMade * 100F) / threePointersAttempted;
double percentage3 = (freeThrowsMade * 100F) / freeThrowsAttempted;

Your DrowRanger method is calling itself infinitely. This is almost always the cause of a StackOverflowException.
This line:
return DrowRanger();
Calls the DrowRanger method, but since you're inside the DrowRanger method it just keeps calling itself infinitely. I think you meant to return the local object:
return DrowRanger;
In general, it is a bad idea to give methods and objects the same name. Also, it is java convention always start method and variable/field names with a lowercase letter.
The output you're seeing is how java prints objects that have not overridden the toString() method. See this post for an explanation of how the toString() method works.

To the first: println prints the output of the toString method of the object. As it is just the normal method inherited by the Object class it just returns the name of the class and the hash of the object.
To your error: it looks like there is an infinite loop somewhere (which has been found).

Hibernate needs a constructor with at least package private (i. e. default) visibility.
Normally a parameterless constructor is necessary (which you implicitly have), but for your select new ... SellerDetailsDto needs a constructor with the 15 parameters which you give in the select statement. (Thought the error message demands a constructor with only the id as a parameter - it looks like if the error is coming from a different select new statement.) You don't have such a constructor.

The problem is that you don't have a constructor in SellerDetailsDto that accepts the parameters that you are passing in the hql query. Add this constructor to your class:
public SellerDetailsDto(String productId, String sellerId,
String sellerSku, Double sellPrice, Double transferPrice,
Double sellerMRP, Double tradusCommission, Double baseShippingFee,
Double addnShippingFee, String propogationLevel,
String propogationValue, String warehouseName, int quantity,
int maxShippingTime, int minShippingTime) {
this.productId = productId;
this.sellerId = sellerId;
this.sellerSku = sellerSku;
this.sellPrice = sellPrice;
this.transferPrice = transferPrice;
this.sellerMRP = sellerMRP;
this.tradusCommission = tradusCommission;
this.baseShippingFee = baseShippingFee;
this.addnShippingFee = addnShippingFee;
this.propogationLevel = propogationLevel;
this.propogationValue = propogationValue;
this.warehouseName = warehouseName;
this.quantity = quantity;
this.maxShippingTime = maxShippingTime;
this.minShippingTime = minShippingTime;
}
This could make some other code you have to stop working, because now there wont' be a default constructor available. To fix that, add a default constructor too:
public SellerDetailsDto() {}

Actually this is problem on your root pom file. You want install lombok in your IDE & add dependency of lombok in root pom file I hope it will work
