write a program to sort string in reverse order using Insertion sort in java


In this core java programming tutorial we will write a program to sort string in reverse order using Insertion sort in java.


Example 1 to sort string in reverse order using Insertion sort in java>
Input = java
Output = vjaa


Example 2 to sort string in reverse order using Insertion sort in java>
Input = javaMadeSoEasy
Output = vysojedaaaaSME


Program/ example to sort string in reverse order using Insertion sort in java>
/*

public class InsertionSortReverseOnString {
   public static void main(String[] args) {
          String stringToBeSorted = "java";
          // String stringToBeSorted= "javaMadeSoEasy"; //Test String
          System.out.println(sort(stringToBeSorted));
   }
   // Insertion Sort - to perform reverse sorting
   static String sort(String s) {
          int tempPos;
          char ch[] = s.toCharArray();
          for (int i = ch.length - 1; i > 0; i--) {
                 tempPos = i;
                 for (int j = i; j > 0; j--) {
                       if (ch[j - 1] < ch[tempPos]) {
                              tempPos = j - 1;
                       }
                 }
                 swap(ch, tempPos, i);
          }
          return new String(ch);
   }
   static void swap(char ch[], int tempPos, int i) {
          char temp = ch[tempPos];
          ch[tempPos] = ch[i];
          ch[i] = temp;
   }
}
/*OUTPUT
vjaa
*/


So in this core java programming tutorial we wrote a program to sort string in reverse order using Insertion sort in java.
