Which one is faster? Integer.valueOf(String string) or Integer.parseInt(String string)?

Question

I want to know which method is faster?

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

Is there any Performance or M

Answer 1

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.
