可以通过以下方法将InputStream转换为File:
import java.io.*;
public class Main {
public static void main(String[] args) {
InputStream inputStream = null;
FileOutputStream fileOutputStream = null;
try {
inputStream = new FileInputStream("input.txt");
File file = new File("output.txt");
fileOutputStream = new FileOutputStream(file);
byte[] buffer = new byte[1024];
int length;
while ((length = inputStream.read(buffer)) != -1) {
fileOutputStream.write(buffer, 0, length);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if (inputStream != null) {
inputStream.close();
}
if (fileOutputStream != null) {
fileOutputStream.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
此代码段首先创建一个InputStream对象来读取文件内容,然后创建一个File对象来写入内容。通过读取InputStream流的内容,并将其写入到File中,实现了InputStream转换为File的功能。
