"Cannot find symbol: Method" but method is defined and declared in Storm.java

In my driver program methods: setDuration, setWind, setPressure, NewStorm, getCategory cannot not be found although they are clearly declared in my Storm.java file. I can't refer to any of them.

And this is the Storm.java.

}
public String toString()
{
return String.format("%9d %8d %10s %4d %9d %10d\n", beginDate,

}
}
I am pretty sure it has something to do with the default constructor that NetBeans creates, I'm just not sure where that exact problem is located..

Java is case sensitive, SetWind is not the same as setWind
The method in Storm is defined as setWind
public static class Storm {
//...
public void setWind(int w) {
//...
}
//...
}
But you are using SetWind in you code NewStorm.SetWind(wind);

Trying to retrieve index from Array using loop

I made a program which stores movie names, hour and time of showing.
I saved the details inputted to arrays and then saved the arrays by getter and setter methods as a record.
In my final method i attempt to use a for loop to print out the details stored in the records but constantly get errors.
Any help to where the issue is would be greatly appreciated.
//Demonstrates usage of loops/adt/gettersetters
import java.util.Scanner;

for (int i = 0; i < 4; i++) {
screenn[i] = i + 1;
String moviename = input("Film for screen " + (i + 1));
namee[i] = moviename;
int moviehour = inputint("what hour does it start?");
hourr[i] = moviehour;
int moviemin = inputint("what min does it start?");
minn[i] = moviemin;

You are getting your assignment wrong. According to OOP The Movie class should store Movie's properties (name, hour, mins, etc) and then on your MainProgram you should store an array of movies. How you create and the usage of these objects is not concern of the class it self. Having said that i re-implemented your mainProgram to:
Ask for each (4) movie attributes.
Create the movie.
add it to a list of movies.
for each movie (4) print its properties.
MovieClass:
public class Movie
{
String name;
int hour , min , screen;
public Movie ( )
{
super ( );
}
public Movie ( String name , int hour , int min , int screen )
{
super ( );
this.name = name;
this.hour = hour;
this.min = min;
this.screen = screen;
}
public String getName ( )
{
return name;
}
public void setName ( String name )
{
this.name = name;
}
public int getHour ( )
{
return hour;
}
public void setHour ( int hour )
{
this.hour = hour;
}
public int getMin ( )
{
return min;
}
public void setMin ( int min )
{
this.min = min;
}
public int getScreen ( )
{
return screen;
}
public void setScreen ( int screen )
{
this.screen = screen;
}
#Override
public String toString ( )
{
return "Movie [name=" + name + ", hour=" + hour + ", min=" + min + ", screen=" + screen
+ "]";
}
}
MainProgram:
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class MainProgram
{
public static void main ( String [ ] args )
{
List < Movie > movieList = new ArrayList < Movie > ( );
for(int i = 1; i <= 4; i++ )
{
int screen = i;
String name = inputString ( "Film for screen "+(i));
int hour = inputInt ("what hour does it start?");
int min = inputInt ("what min does it start?");
Movie movie = new Movie ( name , hour , min , screen );
movieList.add ( movie );
}
print("Cineworld Movies For Tonight");
for( Movie movie : movieList)
{
print ( "" );
print ( Integer.toString ( movie.getScreen ( ) ));
print (movie.getName ( ));
print (Integer.toString ( movie.getHour ( ) ));
print ( Integer.toString ( movie.getMin ( ) ));
}
}
public static String inputString ( String message )
{
Scanner scanner = new Scanner ( System.in );
print ( message );
String answer = scanner.nextLine ( );
return answer;
}
public static String print ( String message )
{
System.out.println ( message );
return message;
}
public static int inputInt ( String message )
{
int number = Integer.parseInt ( inputString ( message ) );
return number;
}
}
Note: as you can see i re-used some of your static methods but if you need something else you have to implement it by yourself.
I/O Example:
Film for screen 1
The Shawshank Redemption
what hour does it start?
19
what min does it start?
30
Film for screen 2
The Godfather
what hour does it start?
20
what min does it start?
15
Film for screen 3
The Godfather: Part II
what hour does it start?
20
what min does it start?
30
Film for screen 4
The Dark Knight
what hour does it start?
21
what min does it start?
15
Cineworld Movies For Tonight
1
The Shawshank Redemption
19
30
2
The Godfather
20
15
3
The Godfather: Part II
20

Change loop condition to
for(int i = 1; i < 10; i++)

Java follows Zero indexing. So in your case question and responses array is of size 10 which means it will iterate from 0 to 9 use for(int i = 1; i < 10; i++) instead for iterating. or use arrayName.length length is a variable provided by JVM which gives you the size of array at runtime.

AS Vishrant mentioned *Java follows Zero indexing. So in your case question and responses array is of size 10 which means it will iterate from 0 to 9 *
in your tester class, you are trying to access 10th index in loop in 2 places
for(int i = 1; i <= 10; i++) (1)
{
noArgSurvey.displayQuestionStats(i);
}
for(int i=1; i<11; i++) (2)
{
noArgSurvey.displaySurveyResults(i);
}
You should to write
for(int i = 0; i < 10; i++) (1)
{
noArgSurvey.displayQuestionStats(i);
}
for(int i=0; i<10; i++) (2)
{
noArgSurvey.displaySurveyResults(i);
}
EDIT Addition
public void displaySurveyResults (int no)
{
for (int j=0; j<10; j++)
System.out.print("Question"+(no)+" : " + question[no]+"Reply"); <<<--------- change [no-1] to [no]
if (responses[respondentID][no] == 0)
{
System.out.print("NO");
}

how to store the file arrays into class and calculate number of people having matching answers as the class's stored answers?

I was trying to calculate each row of the file having matching answers as the exam solution as well counting each row's number of right answers using the exam solution.
I tried to calculate the number of people having the right answers as the test answers stored in the class, once reading the file and storing the file arrays into the class - after placing the file arrays into class constructor to calculate the answers, but I can't, as I get the wrong answers where the class doesn't calculate.
How do you solve this in Java, where I can calculate and store the file arrays into the class?

Adding number in two dimensional table

I got for example two dimensional table 3x2 where all element have got 4x minus :"----". If I write in program for example 32. The first number tells us what number it is and second how many number is in row.
it will make my table like this (32):
---- ---- 33-- ----
---- ---- -> ---- ----
---- ---- ---- ----
Then when we write another one (53): it will check table [0][0] if it is empty and if it is not it will be checked table [1][0] and table [0][1] if both are empty it will select table with lower number in this case table [0][1].
33-- ---- 33-- 555-
---- ---- -> ---- ----
---- ---- ---- ----
there we can put other numbers:
33-- 555- 33-- 555-
---- ---- -> 444- 22--
---- ---- 333- 222-
we insert number in empty place- when all place is not empty we insert number there where
is more "-" symbols - we take number 42 and in 33-- change it on 3344
33-- 555- 3344 555-
444- 22-- -> 444- 22--
333- 222- 333- 222-
if we want insert more number in place where is not enough "-"- program ends
I started like this:

but when I insert number 32 it write:
33-- 33--
33-- 33--
33-- 33--
How can I make program where will check the lowest table and insert number?

It is simply a matter of searching for the best free slot and inserting there. You may also find it easier to think of what you have as a three dimensional array, not a 2 dimensional one.
