Question

Can Java use a String as an index array key? Example:

array[\"a\"] = 1;

Answer 1

No they can't. But they can use chars the ASCII value of the alphabet will be used as the key index

Consider

    String[] a = new String['a' + 1];
    a['a'] = "Hello";
    int[] b = new int['a' + 3];
    b['c'] = 5;

    System.out.println(a[97]);
    System.out.print(b[99]);

This will output

Hello
5
