通过套接字发送的字符串与应有的字符串不匹配

Question

Using a PrintWriter in java (server) to send data through a socket:

JAVA

out = new PrintWriter(client.getOutputStream(), true);
out.println("p1");

Then when I get this value in flash (client):

FLASH AS3

line = socket.readUTFBytes(socket.bytesAvailable);

This if statement is not run:

if (line == "p1") {

And when I trace line to, I get p1 in the output (though when I put in a breakpoint and run in debug, it shows line as being equal to "p1, rather than "p1").

Answer 1

Probably because

out.println("p1");

will append a line separator (line feed and/or carriage return, depending on platform, configuration etc.). I suspect that's why your debugger show the value as "p1 (since the next line would contain the closing quote). I suspect you want:

out.print("p1");

and close or flush the writer (as appropriate).

I note your comment that your string equality is performed in Flash (so the .equals() comments don't apply)

Answer 2

To compare String objects in java use .equals() method instead of "==" operator

if (line == "p1") 

should be

if (line.equals("p1")) 

Answer 3

Check with line.toString()
if (line.toString() == "p1") {
