Chapter 12, Problem 10PP
Program Plan Intro
“GroupHolder” class
Program Plan:
- Import required package.
- Define “Main” class.
- Define “GroupHolder” class
- Create an array list “items” from “GroupHolder” class.
- Method definition for “findGroupNodeFor”
- Declare variable using “GroupNode” type.
- Set node “n” to “null”.
- Set “found” to “false”.
- Check condition using “while” loop
- Compute next node.
- If “n” equal to “s”, then set “found” to “true”.
- If found, then returns the value of “n”.
- Otherwise, returns null.
- Method definition of “addItem”.
- Call “findGroupNodeFor” method and store it to a variable “n”.
- If “n” is null, then add it to “items”.
- Method definition for “getRepresentative”.
- Call “findGroupNodeFor” method and store it to a variable “n”.
- Check condition using “while” loop.
- Set node to link value at node
- Finally returns the data at node.
- Set node to link value at node
- Method definition of “getAllRepresentatives”.
- Create an array list.
- Add data to “items”.
- Finally returns the result.
- Method definition of “inSameGroup”.
- Assign representative for string “s1” and store result to “r1”.
- Assign representative for string “s2” and store result to “r2”.
- Returns result.
- Method definition of “union”
- Assign representative for string “s1” and store result to “r1”.
- Assign representative for string “s2” and store result to “r2”.
- Check condition.
- Find group node for “r1” and “r2”.
- Create “GroupNode” class.
- Declare required variables.
- Create constructor for “GroupNode” class.
- Create parameterized for “GroupNode” class.
- Define main function.
- Create object “g” from “GroupHolder” class.
- Add item to “g” by calling the method “addItem”.
- Display groups by calling the method “getAllRepresentatives”.
- Join groups by calling the method “union”.
- Display groups after performing unions operations.
- Check “a” and “e” is in same group by calling method “inSameGroup”.
- Check “a” and “f” is in same group by calling method “inSameGroup”.
- Define “GroupHolder” class
