This is the encryption code I wrote for an assignment, and it is working as it should I believe.. however in the assignment he says that "The String, Peach, encrypts to: <OMQT" I am getting this "OM<QT" which is very close.. but I'm not sure if I am doing anything wrong. The assignment asked to use the following algorithm: 1. subtract 20 from numeric coe of each character. 2. reverse the resulting string. 3. swap first an last characters.

public class encryption {
   public static void main(String[] args) {
      System.out.print(encrypt("Peach"));

   }
//accepts a string and returns the string in reverse
	public static String reverse(String s){
		String result = "";
      
      for (int i = 0; i < s.length(); i++) {
         result = s.charAt(i) + result;
      }
		return result;
	}

//accepts a string and returns an encrypted version of that string
	public static String encrypt(String s) {
		String str = "";
      int length = str.length();
      
      for (int i = 0; i < s.length(); i++) {
         char c = s.charAt(i);
         c = (char)(c - 20);
         str += c;
         str = (reverse(str));
   
         }
         length = str.length();

         str = str.charAt(length - 1) + str.substring(1, length-1) + str.charAt(0);
 
      
      System.out.println( "encrypt Not Yet Implemented." );
		return str;
	}
}

I have seen a problem and tested your code and now it is working! The problem is because you have to reverse the whole thing, not reverse each char. Here is the code below:

public class encryption {
	public static void main(String[] args) {
		System.out.print(encrypt("Peach"));

	}

	// accepts a string and returns the string in reverse
	public static String reverse(String s) {
		String result = "";

		for (int i = 0; i < s.length(); i++) {
			result = s.charAt(i) + result;
		}
		return result;
	}

	// accepts a string and returns an encrypted version of that string
	public static String encrypt(String s) {
		String str = "";
		int length = str.length();

		for (int i = 0; i < s.length(); i++) {
			char c = s.charAt(i);
			c = (char) (c - 20);
			str += c;

		}
		str = (reverse(str));
		
		length = str.length();

		str = str.charAt(length - 1) + str.substring(1, length - 1)
				+ str.charAt(0);

		System.out.println("encrypt Not Yet Implemented.");
		return str;
	}
}

I hope this helped

It did ! I actually just realized I had reverse in my loop on accident right before I read this! Thank you for your response though!
