如何在Java中将InputStream转换为字节数组？
Java中的InputStream类提供read()方法。此方法接受字节数组，并将输入流的内容读取到给定的字节数组。
示例
import java.io.BufferedInputStream;
import java.io.IOException;
import java.io.InputStream;
public class StreamToByteArray {
public static void main(String args[]) throws IOException {
InputStream is = new BufferedInputStream(System.in);
byte [] byteArray = new byte[1024];
System.out.println("Enter some data");
is.read(byteArray);
String s = new String(byteArray);
System.out.println("Contents of the byte stream are :: "+ s);
}
}输出结果
Enter some data hello how are you Contents of the byte stream are :: hello how are you
