Quick Eclipse Question

In Eclipse, can you automatically generate Javadoc AS COMMENTS IN THE CODE? I only found out how to directly generate exported HTML Javadoc files from the (uncommented) code, but that's not what I'm looking for.

/**
 * Learn2Javadoc.
 *
 * You fail at failing.
 * @author Anonymous
 */
public class Fail {
    /**
     * Shame on you.
     *
     * @param x First operand.
     * @param y Second operand.
     * @returns the sum of both operands
     */
    public int sum(int x, int y) {
        return x + y;
    }
}
