Thread: Need help fixing the While Loop to stop printing "END", I don't know where I am going wrong, Please help!

Data input is get.String and get.Int. Everything works except for at the end it prints "END" which is the condition "if sn is END" then the while loop should stop, but I can not get it to stop printing END after it has stopped. I am a Beginner Student Programmer. Thanks in advance.

Example Data input:
A N Other
100
B N Other
40
C N Other
39
D N Other
20
END

Expected Results:
A N Other Pass
B N Other Pass
C N Other Fail
D N Other Fail

Actual Results:
A N Other Pass
B N Other Pass
C N Other Fail
D N Other Fail
END Fail


public class Main
{

public static void main( String args[] )
{

String sn = BIO.getString();
String en = "END";


while ( sn != en )
{


int cw = BIO.getInt();

if (cw >= 40)
{

System.out.printf(sn + " Pass ");

sn = BIO.getString();

}

else if (cw <= 39)
{

System.out.printf(sn + " Fail ");

sn = BIO.getString();

}

}
}

}
