无法从java文本文件检索信息

我已经创建了一个非常简单的java程序（我只是一个初学者），该程序将数组中的数据存储在程序末尾的文本文件中；这个很好用。当程序再次运行时，我遇到问题。它应该检索所有数据，但不会。我已经使用：

System.out.println（“测试”）对其进行了测试我正在使用的函数似乎正在启动，并且文本文件具有正确的数据

以下是函数：

  public static void getArrayData(String [][] array){


      try {
         Scanner scan2 = new Scanner(new File("arrayData.txt"));

         System.out.println(array.length);

         for(int i=0; i<array.length;  i++)
         {
            for(int j=0; j<array[i].length; j++)
            {
              System.out.println("Test 1");
              System.out.println(array[i][j]);

              if ( ! scan2.hasNext() )  //if there's nothing left to read
                  return; 

               array[i][j]=scan2.next(); 

            }  
         }


      } 

      catch (FileNotFoundException e)
         { 
         System.out.println("Test 2");
         e.printStackTrace(); 
         }    

   }

试一试{
Scanner scan2=新扫描仪（新文件（“arrayData.txt”）；
System.out.println（数组.长度）；
对于（int i=0；i您如何调用
getArrayData
？您将传递给此方法的数组是什么？@almasshaikh simpleAI2.getArrayData（数组）；@almasshaikh simpleAI2是我的类的名称数组的内容是什么。您能在您的问题中发布代码以便我们提供帮助吗？@almasshaikh内容发生了变化。我将发布完整的代码
