Really simple comparision

[sesstreets]

If I have the variable choice being inputted by the user, how can I use a non case sensitive comparison?

Basically without doing this:
[PHP]
choice = "a";

if(choice == "a" || choice == "A")
{...}[/PHP]

Always use the .equals method for comparing strings in Java.
There's also an equalsIgnoreCas e method.

Always use the .equals method for comparing strings in Java.
There's also an equalsIgnoreCas e method.

but in that case, you have to override the equals method of the Object class for creating a meaningful comparison.

If you use the default ".equals" method of the Object, you are geting the same "==" comparison only.

There's no need to override anything. Like I said in my last response there is an equals and an equalsIgnoreCas e method.

If you use the default ".equals" method of the Object, you are geting the same "==" comparison only.

That is not true. == compares equality of object references.
Try it with some code and give two different references the same string value. == will be false but .equals will be true.
Read about it in Sun's Java tutorial.

well I tried something like the following:

		String one = "abc";
		String two = "abc";
		System.out.println(one==two);
		System.out.println(one.equals(two));
		System.out.println(one=="abc");
		System.out.println(one.equals("abc"));
		System.out.println(two=="abc");
		System.out.println(two.equals("abc"));

and all resulted "true"
in my eclipse.
can you mention, in which case, "==" and ".equals" will return different result?

Change your first line to:

[code=java]
String one= new String("abc");
[/code]
... and run your code again.

Back to the original question, you could use the String.toLowerC ase (or String.toUpperC ase) method.
Example:
[CODE=java]
String one = new String("abc");
String two = new String("ABC");
if(one.toLowerC ase.equals(two. toLowerCase))
{
// It will come here, as both are "abc" in lower case
}

method equalsIngoreCas e combines that into a single method.
