DataInputStream的readUTF()

摘要: DataInputStream的readUTF()

public static void main(String[] args) throws Exception
{
byte b[]=-#34;哈哈123-#34;.getBytes();
DataInputStream dis1=new DataInputStream(new ByteArrayInputStream(b));
try
{
System.out.println(dis1.readUTF());
}
catch(EOFException ex)
{
ex.printStackTrace();
}
}


想不明白，为何老报：

java.io.EOFException
at java.io.DataInputStream.readFully(DataInputStream.java:268)
at java.io.DataInputStream.readUTF(DataInputStream.java:639)
at java.io.DataInputStream.readUTF(DataInputStream.java:610)
at net.TSocket1.main(TSocket1.java:22)

EOFException

EOF = End Of File

读到头了

不够长

---

try{
byte b[]=-#34;哈哈123-#34;.getBytes();

BufferedReader in=new BufferedReader(new InputStreamReader(new ByteArrayInputStream(b),-#34;UTF8-#34;));
System.out.println(in.readLine() );

}catch(Exception e){

}

你自己看一下源代码了解一下

读取UTF的时候 具体做了 什么你就清楚了为什么抛出EOFException

我看了源码了，还是不明白，唉。
