Question

Here is a java line of code that i have failed to understand.

 String line = "Some data";//I understand this line
 int size;//I understand this line too

 size = Integer.valueOf(line,16).intValue();//Don't understand this one

What i know is Integer.ValueOf(line) is the same as Integer.parseInt(line) , is not so? Correct me if i am wrong; Thanks.

Answer 1

Integer.ValueOf(line,16) converts string value line into an Integer object. In this case radix is 16.

intValue() gets the int value from the Integer object created above.

Furthermore, above two steps are equivalent to Integer.parseInt(line,16).
