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。
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); } }
Enter some data hello how are you Contents of the byte stream are :: hello how are you
