File- String path+File(String path)+exists() : booleanFileInputStream- File file+FileInputStream(File file)+close() : void 通过以上步骤和示例代码,你应该能够解决“java new File FileInputStream No such file or directory”的问题了。祝你编程顺利!

StringfilePath="test.txt";Stringcharset="UTF-8";InputStreaminputStream=newFileInputStream(filePath);Readerreader=newInputStreamReader(inputStream,charset); 在上面的代码中,我们创建了一个名为inputStream的FileInputStream对象,并将其作为InputStreamReader的构造函数的参数传入。构造函数的第二个参数charset指定...
