Sample 1. Sorting an arraylist using Collections.sort

List<String> myList = new ArrayList<String>();

myList.add("D");

myList.add("A");

myList.add("B");

myList.add("C");

myList.add("E");



System.out.println(myList); // Unsorted



Collections.sort(myList);



System.out.println(myList); // Sorted

Sample 2. Sort a List using Collections.sort and comparator

Collections.sort(listClassInfo,new Comparator<ClassInfoBean>(){

            public int compare(ClassInfoBean s1,ClassInfoBean s2){

                  if(s1.name.compareTo(s2.name) < 0){

                     return -1;

                  } else {

                     return 1;

                  }

                  

}});

Sample 3. Sorting elements of a set using TreeSet

Set<String> mySet = new HashSet<String>();

mySet.add("D");

mySet.add("A");

mySet.add("B");

mySet.add("C");

mySet.add("E");



System.out.println(mySet); // May be Sorted but sorting is not guaranteed 



mySet = new TreeSet<String>(mySet);



System.out.println(mySet); // Sorted

Sample 4. Order Collection using google.common.collect.Ordering

Collection<Employee> sortedEmployeess = Ordering.from(new Comparator<Employee>() {

   @Override

   public int compare(Employee employee1, Employee employee2) {

      return employee1.getAge() - employee2.getAge();

   }

};).sortedCopy(employees);

            if(a[j] > a[j]){

               int temporary = a[j];

               a[j] = a[i];

               a[i] = temporary;

            }

         }
