Thread: Write a Java program to reverse a string

import java.util.Scanner;
 
class RicMain
{
	public static void main(String args[])
	{
		{
	        Scanner rc = new Scanner(System.in);
 
	        System.out.print("Input a string: ");
	        char[] letters = rc.nextLine().toCharArray();//When inputting, what happens then?
 
	        System.out.print("Reverse string: ");
	        for (int i = letters.length - 1; i >= 0; i--)//What is happening inside the for loop? 
	        {
	            System.out.print(letters[i]); 
	        }
	        System.out.print("\n");
	    }
	}
}

Please help me understand this code. I had to find the solution online because I didn't know where to begin, so I got this code, tried it on my Java and it worked, but I have trouble understanding it. So After I input my name, how does the for loop reverse it?
I know rc.nextLine() is where I input characters, but when I add toCharArray(), does it convert that array into a string or something?
Please explain how toCharArray() works.

toCharArray() basically converts a string into an array, right? (I did not look at the link you showed me yet)
