StringfilePath="path/to/your/file.txt"; 1. 第二步: 使用该路径创建一个File对象 使用第一步中定义的文件路径,我们需要创建一个File对象。这可以通过如下代码实现: Filefile=newFile(filePath); 1. 第三步: 创建一个FileInputStream对象并传入File对象作为参数 最后一步是创建一个FileInputStream对象,并将第...
首先,我们需要使用字符串创建一个File对象。File类是Java IO库中用于操作文件和目录的类。我们可以使用File的构造函数,将字符串作为参数传递进去,来创建一个File对象。 StringfilePath="C:/path/to/file.txt";Filefile=newFile(filePath); 1. 2. 接下来,我们需要创建一个FileInputStream对象。我们可以使用FileInp...
