java - Use a variable within a variable?

Question

I have several fields, each one is like this:

field1
field2
field3
...

Using a loop with a counter, I want to be able to say fieldx. Where x is the value of the counter in that loop. This means if I have 6 entries in my array, fields1 - field6 will be given values.

Is fieldx possible?

Answer 1

You can do it with reflection, but in general it is better if you can declare your fields in an array. Instead of:

SomeType field1;
SomeType field2;
SomeType field3;
...
SomeType field6;

You can do this:

SomeType[] fields = new SomeType[6];

Then you can loop over the array setting the values:

for (int i = 0; i < fields.length; ++i)
{
    fields[i] = yourValues[i];
}
