无法从静态引用非静态

Question

所以，我试图自己学习JAVA并且遇到臭名昭着的非静态变量，这不能从静态上下文中引用＃34;错误。

我知道这对你们重复，但我不明白为什么会这样......

public class JavaApplication1 {

public static void main(String[] args) {
    /** Error comes from line below */
    Anagram Pay = new Anagram(3,"PAYPAL");
    System.out.println(Pay.horzArray);
}

public class Anagram{
private int vertArray;    
private int horzArray; 
private String starterWord;
private int wordLength;
private int diagonalMax;

public Anagram(int verticalArray, String inputWord){
vertArray = verticalArray;
starterWord = inputWord;
wordLength = starterWord.length();
if (vertArray > 2)
      diagonalMax = vertArray - 2;
else
      diagonalMax = 0;

horzArray = wordReducer(wordLength);
}

public int wordReducer(int word){
int step = 1;
int horzValue = 0;
while (word > 0)
if (step == 1) {
    word = word - vertArray;
    step = step + 1;
    horzValue = horzValue + 1;
} else {
  word = word - diagonalMax;
  step = 1;
  horzValue = horzValue + diagonalMax;
}
return horzValue;
}
        }
};
