1. Bizarre problem with Strings obtained from readLine

15.21.3 Reference Equality Operators == and != If the operands of an equality operator are both of either reference type or the null type, then the operation is object equality. A compile-time error occurs if it is impossible to convert the type of either operand to the type of the other by a casting conversion (5.5). The run-time values of the ...

2. String comparsion

My rule of thumb is to always compare objects (not just Strings!) with equals, not ==. If you are worried about NPE, you could always write a utility method: [code] public static boolean equals(Object x, Object y) { return x==null ? y==null : x.equals(y); /code] An exception to the rule of thumb will be clear to you as you code it. ...

We know that a String object is immutable.

19. How do I create a String class from scratch?

"special" != "unique" Though actually... the compiler knows about Integers, inasmuch as it knows to map ints to them sometimes. But that's during the code generation stage. What other object types have a special meaning during just the parsing stage? Offhand I can't think of any, but I'll bet someone else will... [added] Arguably null... Message was edited by: paulcw

20. String program

You can use regular expressions, or regular String or StringBuilder methods, if you just want to stick hyphens in there. But if the string represents a date, then a better approach is probably to use java.text.SimpleDateFormat to parse the String into a Date object, and keep use that. If you need a different String output, create a different SimpleDateFormat with a ...

That doesn't even compile, right? (It does help if you describe the problem, and that includes telling us what the symptoms of the problem are.)

You are new and have directly gone digging into servlets? And JDBC?

But please do yourself the favour and go back to the basics before delving ...

There are acutally times when you want to invoke the constructor that takes a string as argument, but doing so with a string literal is rather pointless. The method String.substring returns a new string which is a view into the original string. They share the same data array. The original string might be very large (an xml document), and the data ...

Hmm, not sure about first answer. Both are the same. A string is an Object like any other. Going String x = "ldskjfglkdsjfg"; is only allowed by the compiler for your convienence.
