[英]Scanner and reading from a file
i have to parse a text file using the Scanner, I know how to use the delimiter to parse the text, but i don't know how to make my program accept a file.txt as an input and then to start chopping it off. 我必须使用扫描仪来解析文本文件,我知道如何使用定界符来解析文本,但是我不知道如何使程序接受file.txt作为输入,然后开始将其切掉。 Can anyone help me with this?
谁能帮我这个? Tnx in advance!
提前Tnx!
Look at the Scanner API. 查看Scanner API。 It has a constructor that will accept a File parameter.
它具有一个接受File参数的构造函数。 Use it.
用它。
String fileName = "fileName.txt";
File file = new File(fileName);
Scanner fileScanner = new Scanner(file);
