in HashMap.Java file variable is declared like this
static final int DEFAULT_INITIAL_CAPACITY = 1 << 4;
why not
static final int DEFAULT_INITIAL_CAPACITY = 16
is it due to performance or just to show that we are using this as the power of 2?

2It is just to show that the number is a power of two. It does not affect performance. – khelwood Jan 11 '22 at 09:23

2There's no performance benefit to using one compile-time constant expression over another. – jsheeran Jan 11 '22 at 09:23
