Question

Is it possible to define array in this way in JAVA, otherwise are there an alternative close this definition?

private final int CONST_0= 0;
private final int CONST_1= 1;
private final int CONST_2= 2;
private final int CONST_3= 3;
private final String[] CONST_TXTRECORDS = new String[] 
                                          {[CONST_0] = "test0",
                                          {[CONST_1] = "test1",
                                          {[CONST_2] = "test2",
                                          {[CONST_3] = "test3"};

Perhaps you should look at enums.

http://docs.oracle.com/javase/tutorial/java/javaOO/enum.html

You can use enums as map keys, using either the generic Map classes or the specialized EnumMap which I guess is a bit more efficient.
