测试文件制作迷宫 [英] Test Files making a Maze

问题描述

我是Java的新手，目前正在用文本文件做一个迷宫.这是如何创建迷宫的示例代码，但是我的问题实际上是让程序读取文本文件，出现此消息:
"Error :java.io.FileNotFoundException: sample_maze2.txt (The system cannot find the file specified)"

这是代码:

Hi I''m new to java and I''m currently making a maze from a text file. Here is example code of how to create the maze, but my problem is actually getting the program to read the text file, this message comes up:
"Error :java.io.FileNotFoundException: sample_maze2.txt (The system cannot find the file specified)"

Here is the code:

public class JavaTest {
	public static void main(String[] args) {
		TextIO.readFile("sample_maze2.txt");
		// sample_maze2.txt has a line with two numbers on it saying how many rows and
		// how many columns of characters there are in the rest of the file.
		// All calls to TextIO.get methods read now read from sample_maze2.txt.
		int rows = TextIO.getInt();  // this is the number of rows in the file (maze)
		int cols = TextIO.getlnInt();  // this is the number of columns in the file (maze)
		char[][] array = new char[6][12];
		// Each line of sample_maze2.txt contains cols number of characters
		// and there are rows number of lines
		for (int i=0; i < rows; i++) {
			for (int j=0; j < cols; j++) {
				array[i][j] = TextIO.getChar();
			}
			TextIO.getln();
		}
		TextIO.readStandardInput(); // This closes the file
		TextIO.putln("Display the maze using 'maze' characters:");
		// In the maze project, whenever you read a '0' you display a wall character
		// whenever you read a '1' you display a path character
		// whenever you read a '2' you display an entrance character
		// whenever you read a '3' you display an exit character
		for (int i=0; i < rows; i++) {
			for (int j=0; j < cols; j++) {
				if (array[i][j]=='0') TextIO.put('*');
				if (array[i][j]=='1') TextIO.put(' ');
				if (array[i][j]=='2') TextIO.put('E');
				if (array[i][j]=='3') TextIO.put('X');
			}
			TextIO.putln();
		}
		
		
	}
}

推荐答案

提供文件的完整路径.

/Fredrik

Provide the full path to your file.

/Fredrik

在您的根文件夹中放入"sample_maze2.txt".当前，代码正在搜索/查找的文件不在指定的路径上.改正它.您可以根据需要使用绝对路径或相对路径.

Put ''sample_maze2.txt'' in your root folder. Currently the file being searched/looked for by the code is not on the path specified. Correct it. You can use absolute path or relative path as per your choice.
