Turning an Int into a String

[Adam Blais]

I'm using a method with prototype InputJTextField(String, int)

The string is supposed to be a number gotten from a method called getYear() that returns an int value. How do I take this int value and turn it into a String so that I can use it in InputJTextField?

 public class Testing5 {

public static void main (String[] args) {
int i = 5;
Integer in = new Integer(i);
String s = in.toString();

// or 

int num = 11;
String str = i + "";
}
}

Wrap the int as an Integer, then call toString.

[James Carman]

String.valueOf( someInt )

[James Carman]

Actually, you can use String.valueOf() on ANYTHING! Even a null reference (which returns the string "null").

Question? (didnt want to start another topic since its connected with this one )

I read about autobox recently and i wonder now do we still have to wrapp primitive variables or autoboxing will do all our job so we can forget about it now ?

You can use autoboxing as long as it's clear to the compiler that a wrapped instance is required from the primitive.

For example, instead of...

Integer in = new Integer(5);

...you can simply use...

Integer in = 5;

Of course, you still can't dereference an int...

String s = 5.toString(); //ILLEGAL

...but you can do this...

String s = ((Integer)5).toString();
