Try this:

lineStr = scanner.nextLine();
	        
	       byte  bytes[] = lineStr.getBytes();
	       char tab = 9;
	       if((char)bytes[0]==((char)tab)) {		   
		 lineStr = "NA" +lineStr;
	       }

simple :)

You must refer to the user inputs as $_POST[aid] and $_POST[apass]. DO NOT refer to them as $aid and $apass (don't even save them as variables if possible). There are many situation where this will come back to bite you in the rear if you do. I will mention the most detrimental one which is called called sql injection. Lets assume that you are saving user data in a sql database and your form page is called rori.com. What do you think you might happen if I typed in something like rori.com?aid=drop+database in the address bar? Your code might pass $aid to the database where it will get executed. You should run some checks on $_POST[aid] and put it into something that does not resemble the variable name $aid then insert it in the database. Just google sql injection if you want a more elaborate explanation.
PS. You should thank whomever turned off global_register on the server so you can't refer to $_POST[aid] as $aid anymore. Then yell at him for ever having it turned on.

Copy and paste the java code here. Then someone can easily point out the errors. Your error message states that it did not find a compiled file called Example.class. Did you see a file called Example.class appear in the same folder after running the javac command?

Javac Example.exe ENTER This command must have failed. Did you not get any error message? Java source code files have the extension .java not exe. Check your book's example closely.
