The Hole Class Description:

For the Hole class, there are three instance variables: the parfor the hole, the length of the hole in yards, and a Boolean valuedindicator of whether the hole is one in which the players’ fulldrives will be measured for distance. John clarifies: The length ofthe hole in yards determines par for the hole. The current standardis:

No more than 250 yards	Par 3
251 to 470 yards	Par 4
471 to 690 yards	Par 5
Greater than 690 yards	Par 6

The distance of drives will only be counted as “full” on holesat least 400 yards long. Both the Hole constructor and a setLengthmethod use the length of the hole to calculate the par for the holeand determine whether full drives on the hole will be measured.There are “getters” for the length and the par of the hole and anisFullDriveHole method that returns true if and only if the hole isone where drives are measured.

The Hole Class:

// instance variables

{
this.setLength(length);

/**

*
* @param length the length in of the hole in yards.
*/
public void setLength(int length)
{
// constants for determining par
final int par3Limit = 250;
  
       // GUIDE: add constants for limitsfor par 4 and par 5
    // GUIDE: set the length of the hole, initializethe instance variable
       // GUIDE: Write an IF-ELSE for asequence of comparisons to

       // GUIDE: Write code to properlyassign a value to this.fullDriveHole
}
