I want to know which method is faster?

Integer.valueOf(String string) or Integer.parseInt(String string)?

Is there any Performance or Memory difference between the two approaches?

I have seen Difference between parseInt and valueOf in java? but this does not explains difference in terms of performance.

    I would not look at performance. The API says that Integer.valueOf(String) is interpreted the same as if it has been passed to Integer.parseInt(String), except it is wrapped into an Integer. I would look at what you need: an Integer or an int.

    Integer.valueOf returns an Integer.

    Integer.parseInt returns an int.
