Newbie here having input problems

Question

Hi, I'm still very new to Java and I'm basically learning it on my own right now. I think my current problem is with the way I'm reading in the input. Since my entire program right now is over 100 lines, I'll only post how I'm reading input in, and how I'm trying to use the input to continue program execution so that I can verify first if my input is correct before I move on to posting snippets of my program. Here's what I'm trying to do:
//Begin code here
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
String cmd="";
while(//condition)
//Print out input options here
//Read input here
cmd = in.readLine();
cmd.trim();
if((cmd == "A') || (cmd == "a"))
      //Process
else if((cmd == "S") || (cmd == "s"))
        //Process
else if((cmd == "B") || (cmd == "b"))
     //Process
else
      System.out.println("Command not recongnized");
}Based on that code above, is the input reading being done correctly? That's the idea of what I'm trying to do in my program, yet it always just says that it doesn't recognize the command. If need be I will start to post more of my code if this example is not sufficient enough. I'm sorry if this is another one of those cookie cutter answer questions, I've just become somewhat frustrated in the last few hours of trying to figure out why my program isn't working. Thank you for any help you may be able to provide.

Answer 1

Shoot, sorry didn't read over my post before posting as I should have. The snippet:
if((cmd == "A') || (cmd == "a"))
      //Process
}Should read:
if((cmd == "A") || (cmd == "a"))
//Process
Sorry about that.
