處理/初始化二維數組（Java）

Question

我一直在爲我的CS類編寫一個程序，並遇到問題。在下面的代碼中，我不斷收到一條錯誤消息：initializeArray(firstArray)和initializeArray(secondArray)。

消息說the method initializeArray(int[][]) is undefined for type processArray。任何人都可以向我解釋我在這裏做錯了什麼。我需要能夠在我的processArray方法中調用方法initializeArray。

public class ProcessArray { 


    // The constructor for the class: it initializes the attributes "rows" and "columns", and also completes the 
    // declarations for the two arrays using the dimensions received. It then calls a private method in the class 
    // to set the values in both arrays to 0. 
    public ProcessArray (int rows, int columns){ 

     int[][] firstArray = new int[rows][columns]; 
     int[][] secondArray = new int[rows][columns]; 

     initializeArray(firstArray); 
     initializeArray(secondArray); 

    } 



    // This private utility method sets the values in both arrays to 0. 
    private void intializeArray(int[][] array){ 

     int rows = array.length; 
     int columns = array[0].length; 

     for(int i = 0; i < rows; i++){ 
      array[i][0] = 0; 

      for(int j = 0; j< columns; j++){ 
       array[i][j] = 0; 
      } 



     } 

    }

你有一個錯字：

intializeArray

initializeArray

以不同的方式
