Calling methods in a loop

I have a problem. If i have to call a bunch of methods with similar names like

String rec1 = Records.getRecord1();
String rec2 = Records.getRecord2();
String rec3 = Records.getRecord3();

is there a way I can do this in a loop?

for example:

for(int count=1;count<4;count++){

rec//count// = Records.getRecord//count//();

No, not if the records are named getRecordN (where N is 1, 2, 3, ...). (Well, you can do it via reflection, but...).

Note that the design of the Records class should have been done differently: Instead of a whole bunch of getRecordN methods, there should have been just one getRecord(int number) method; then it would be easy:
