reverse string algorithm java using tochararray code example

Example 1: Java reverse string array

// reverse string array in java using collections
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class ReverseStringArrayUsingCollections
{
   public static void main(String[] args)
   {
      // creating list of strings
      List<String> li = new ArrayList<String>();
      li.add("java");
      li.add("core");
      li.add("world");
      li.add("hello");
      System.out.println("Given list: " + li);
      Collections.reverse(li);
      System.out.println("After using collections: " + li);
   }
}

Example 2: reverse string array java

import java.util.Arrays;
public class ReverseStringArrayInJava
{
   public static void main(String[] args)
   {
      String[] strHierarchy = new String[]{"Junior Developer","Senior Developer","Team Lead","Project Manager","Senior Manager","CEO"};
      System.out.println("Given string array: " + Arrays.toString(strHierarchy));
      for(int a = 0; a < strHierarchy.length / 2; a++)
      {
         String strTemp = strHierarchy[a];
         strHierarchy[a] = strHierarchy[strHierarchy.length - a - 1];
         strHierarchy[strHierarchy.length - a - 1] = strTemp;
      }
      System.out.println("Reversed string array: ");
      for(int a = 0; a < strHierarchy.length; a++)
      {
         System.out.println(strHierarchy[a]);
      }
   }
}
