    Default Declaring variables in constructor and compiling

    import java.util.*;
     
    class WordStore
    {
     
    public WordStore(int n){
    int number = n;
     
    }
     
    public String[] storewords = new String[number];
    public int count=0;
     
    public void add(String word){
        storewords[count] = word;
        count=count+1;
    }

    I am not sure were to declare the String Array storewords, so i just made it public and the same with int count. I tried putting them in the constructor, but it wouldn't recognise the variable.

    There are certain conditions I have to meet, like the method add is declared
    public void add(String word)
    and when add is callled it just stores a word in the array (theres another loop in another class that calls it, and i got to leave it unchanged.

    The problem I am getting it doesn't recognise the variable number

    I have solved the problem, i declared another integer as public, then made it equal to the constructor argument.

    import java.util.*;
     
    class WordStore
    {
     
    public int number = 0;
    public WordStore(int n){
    number = n;
     
    }
     
    public String[] storewords = new String[number];
    public int count=0;
     
    public void add(String word){
        storewords[count] = word;
        count=count+1;
    }
     
    }

    I think private would be even better
