i got pretty far on this code but the complier says there is an error. If you can help me solve this problem that would be wonderful!

replace characters with similar-looking symbols: e becomes 3, i becomes 1, l becomes 7, and o becomes 0. Write a program to carry out these replacements with a sample string.
Complete the following code:

public class ReplacementTester
{
   public static void main(String[] args)
   {
      String greeting = "Hello, elite hacker!";
      greeting = greeting.replace("e" , "3");
      greeting = greeting.replace("i" , "1");  
      greeting = greeting.replace("l" , "7");
      greeting = greeting.replace("o", "0");
      
// call the replace method four times

      System.out.println(modifiedGreeting);
      System.out.println("Expected: H3770, 371t3 hack3r!");
   }
}

*Edited: code tags fixed.

What error does it give you?

Keep in mind, saying "there's a compile error" doesn't help us much.

Also:

The error is because you've used a variable that doesn't exist. In the println call, you're referencing modifiedGreeting, but you use greeting to hold your string. Just use greeting instead.
