Say you want to build a reference to a string lower in your code based on some strings created higher in the code.
An example of what I mean is below. Say you create a few strings that vary only by the last character and you'd like to be able to build up these string names later in a for loop using the "test" prefix plus the for loop index.
What I'd like to be able to do is build a new string that references, say, test1 below, for example.
I'm not sure how to do this or if Java allows this, but my example is below.
Anybody's input would be appreacited.
String test1 = "AToyota";
String test2 = "A man a plan a canal panama";
String test3 = "Dad";
String test4 = "Mom";
String test5 = "Cat";
int i;

// want to build a String aString
// to "point" to test1 created above.
// want to build the string dynmaically.
String aString = ("test" + "1");
// this method (line of code above) doesn't
// work and just creates a new string aString,
// not a "pointer" to the test1 string created
// above.
if (pal1.isPalendrome(aString))
{
System.out.println("String " + aString + " is a palendrome");
}
else
{
System.out.println("String " + aString + " is not a palendrome");
}

You could use some reflection to do that.
Class.forName(classname).getDeclaredField(fieldname); /returns a Field object
So if you use:

This might work.

Wow, this is cool.
Thanks.
It might be easier to just use an array. <s>

Well, yeah - but that only works if your Fields are constant. .

You should probably also take a look at java.util.Map
