I got errors when ran the codes provided

I am studying the workshop video The Thing About Strings, I ran the code provided for this video

public class Thing { public static final String ANSI_RESET = "\u001B[0m"; public static final String ANSI_RED = "\u001B[31m"; public static final String ANSI_GREEN = "\u001B[32m";

public static void explore(String assumption, boolean result) { StringBuilder sb = new StringBuilder(); if (result) { sb.append(String.format("%sYAY!%s", ANSI_GREEN, ANSI_RESET)); } else { sb.append(String.format("%sWAT???!%s", ANSI_RED, ANSI_RESET)); } sb.append(" "); sb.append(assumption); if (!result) { sb.append(" (Your assumption is incorrect)"); } System.out.println(sb.toString()); }

public static void main(String[] args) { // Your assumptions here int firstNumber = 12; int secondNumber = 12; explore("Primitives use double equals", firstNumber==secondNumber);

} }

And I got the following errors.
