The composite design pattern in Salesforce Apex is where we implement nested objects of the same class. This pattern<\/a> is used in the case of hierarchical structure. The data structure pattern of the composite pattern is tree type.<\/p>\n

Problem:<\/h2>\n

In a company, there are many types of employees. The company wants to store employees’ data and their subordinates.<\/p>\n

Solution:<\/h3>\n

To resolve this problem we need to implement the composite pattern because of the hierarchical employee structure.
\npublic class EmployeeData {
\nprivate String name;
\nprivate String department;
\nprivate integer salary;
\nprivate List<Employee> subordinates;
\n\/\/ constructor
\npublic EmployeeData (String name, String department, Integer salary) {
\nthis.name = name;
\nthis.department = department;
\nthis.salary = salary;
\nsubordinates = new List<Employee>();
\n}
\npublic void add(EmployeeData e) {
\nsubordinates.add(e);
\n}
\npublic void remove(EmployeeData e) {
\nfor(Integer i = subordinates.size() - 1; i >= 0; i--) {
\nif(subordinates[i].equals(e)) {
\nsubordinates.remove(i);
\n}
\n}
\n}
\npublic List<Employee> getSubordinates(){
\nreturn subordinates;
\n}
\n}
\npublic class CompositePatternDemo {
\npublic static void validateResult() {
\nEmployeeData CEO = new EmployeeData('John','CEO', 30000);
\nEmployeeData headSales = new EmployeeData('Robert','Head Sales', 20000);
\nEmployeeData headMarketing = new EmployeeData('Michel','Head Marketing', 20000);
\nEmployeeData clerk1 = new EmployeeData('Laura','Marketing', 10000);
\nEmployeeData clerk2 = new EmployeeData('Bob','Marketing', 10000);
\nEmployeeData salesExecutive1 = new EmployeeData('Richard','Sales', 10000);
\nEmployeeData salesExecutive2 = new EmployeeData('Rob','Sales', 10000);
\nCEO.add(headSales);
\nCEO.add(headMarketing);
\nheadSales.add(salesExecutive1);
\nheadSales.add(salesExecutive2);
\nheadMarketing.add(clerk1);
\nheadMarketing.add(clerk2);
\n\/\/print all employees of the organization
\nSystem.debug('CEO:' + CEO);
\nfor (EmployeeData headEmployee : CEO.getSubordinates()) {
\nSystem.debug('Head Employee:' + headEmployee);
\nfor (EmployeeData employee : headEmployee.getSubordinates()) {
\nSystem.debug('Simple Employee:' + employee);
