MySocketServer.java 使用或覆盖一个不鼓励使用的API。

javac -deprecaton MySocketServer.java

MySocketServer.java:48: 警告：
在java.awt.TextArea中的appendText(java.lang.String)已经不提倡使用
MySocketServer.java:49: 警告：
在java.io.DataInputStream中的readLine()已经不提倡使用

用什么可以替换appendText()和readLine()??

[jeanven]

append(),

[iamabug]

那readLine()呢?

[0legend]

String readLine()
Deprecated. This method does not properly convert bytes to characters. As of JDK 1.1, the preferred way to read lines of text is via the BufferedReader.readLine() method. Programs that use the DataInputStream class to read lines can be converted to use the BufferedReader class by replacing code of the form:
DataInputStream d = new DataInputStream(in);

with:
BufferedReader d
= new BufferedReader(new InputStreamReader(in));

[skyyoung]

BufferedReader reader = new BufferedReader(new InputStreamReader(socket.getInputStream()));

[iamabug]

能不能说的具体一点。
DataInputStream in =new DataInputStream(
new BufferedInputStream(Connect.getInputStream()));
s = readLine();
怎么改？

[iamabug]

thinking in java 里也是这么写的.
我想这应该是它的JDK的版本低的缘故吧,我的是JDK1.3.
但是readLine()==????
可以再加分!

BufferedReader d
= new BufferedReader(new InputStreamReader(in));
d.readLine();

谢谢了.以上问题解决了.马上散分!
