以下示例显示java.io.DataInputStream.readByte()方法的用法。
package com.jc2182;
import java.io.ByteArrayInputStream;
import java.io.DataInputStream;
import java.io.IOException;
import java.io.InputStream;
public class DataInputStreamDemo {
public static void main(String[] args) throws IOException {
InputStream is = null;
DataInputStream dis = null;
byte[] buf = {65, 0, 0, 68, 69};
try {
// create new byte array input stream
is = new ByteArrayInputStream(buf);
// create data input stream
dis = new DataInputStream(is);
// readBoolean till the data available to read
while( dis.available() >0) {
// read one single byte
byte b = dis.readByte();
// print the byte
System.out.print(b+" ");
}
} catch(Exception e) {
// if any I/O error occurs
e.printStackTrace();
} finally {
// releases any associated system files with this stream
if(is!=null)
is.close();
if(dis!=null)
dis.close();
}
}
}
