问题
I am trying to implement autoboxing but it's showing an error:
Cannot convert from int to integer.
package JavaTraining;
public class Wrap {
public static void main(String ar[])
{
Integer a=100;
String i=a.toString();
System.out.println(i);
System.out.println(a);
}
}
Eclispe version is 3.1

(This is relevant to Eclipse specifically) -
You need to change your Compiler compliance level to at least 1.5.
Project -> Properties -> Java Compiler -> Compiler compliance level
