What is the difference between parseInt and valueOf in Java?

If you look at the API... Integer.valueOf(String) is interpreted exactly as String did Integer.parseInt(String). However, valueOf(String) returns the object to newInteger() and parseInt(String) returns the int default datatype.

If you want to write some efficient code with Integer.valueOf(int), you need to write an eye-catching code like below. Integer k = Integer.valueOf(Integer.parseInt("123"))

In conclusion, when converting a string, you can use valueOf(String) if you want to receive it as an object other than the basic data type. If not, use parseInt(String).
