处理/初始化2D数组(Java)

Question

我一直在尝试为我的CS类写一个程序，我有一个问题。在下面的代码中，我一直在initializeArray(firstArray)和initializeArray(secondArray)处获得错误消息。

消息显示the method initializeArray(int[][]) is undefined for type processArray。有人能告诉我我哪里做错了吗?我需要能够调用方法initializeArray在我的processArray方法。

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;
            }

        }
    }

你打错字了:

intializeArray

initializeArray
