Program execution doesn`t stop when you close the window

I’m making my own programming language for fun and I hava added the goto command.
This is the code of the function that executes the code:

class Var {
  char type;
  String name;
  Object univ;
  Var(Object i, String n, char t) {
    univ = i;
    name = n;
    type = t;
  }
}

int compile(String[] rows) {
  int kurwar = 0;
  if (rows[0] == "" && rows.length == 1) {
    println("Code is empty");
    return 1;
  }
  for (int r = 0; r < rows.length; r++) {
    String row = rows[r];
    if (row.contains("goto")) {
      r = int(row.substring(5, row.length())); 
      row = rows[r];
    }
    if (row == "nop") continue;
    if (row == "end") return 0;
    if (row.contains("print")) {
      print(row.substring(6, row.length()).replace("\\n", "\n")); 
      continue;
    }
    /*if (row.contains("println")) {
      print(row.substring(8, row.length()).replace("\\n", "\n") + "\n"); 
      continue;
    }*/
    if (row.contains("let")) {
      String[] params = split(row.substring(4, row.length()).replace(" ", ""), ",");
      Object val;
      String v = params[2];
      char type;
      switch(params[0]) {
      case "int":
        val = int(v);
        type = 'i';
        break;
      case "float":
        val = float(v);
        type = 'f';
        break;
      case "boolean":
      case "bool":
        val = boolean(v);
        type = 'b';
        break;
      case "string":
      case "String":
        val = v;
        type = 's';
        break;
      default: 
        continue;
      }
      variables[kurwar] = new Var(val, params[1], type);
      kurwar++;
      continue;
    }
    if (row.contains("++")) {
      String params = row.substring(3, row.length()).replace(" ", "");
      int varInd = searchVar(params);
      switch(variables[varInd].type) {
      case 'i':
      case 'f':
        variables[varInd].univ = ((int) variables[varInd].univ) + 1;
        break;
      case 'b':
        variables[varInd].univ = !((boolean) variables[varInd].univ);
        break;
      }
      continue;
    }
    if (row.contains("--")) {
      String params = row.substring(3, row.length()).replace(" ", "");
      int varInd = searchVar(params);
      switch(variables[varInd].type) {
      case 'i':
      case 'f':
        variables[varInd].univ = ((int) variables[varInd].univ) - 1;
        break;
      case 'b':
        variables[varInd].univ = !((boolean) variables[varInd].univ);
        break;
      }
      continue;
    }
    if (row.contains("=")) {
      String[] params = split(row.substring(2, row.length()).replace(" ", ""), ",");
      int varInd = searchVar(params[0]);
      String val = params[1];
      switch(variables[varInd].type) {
      case 'i':
        variables[varInd].univ = int(val);
        break;
      case 'f':
        variables[varInd].univ = float(val);
        break;
      case 'b':
        variables[varInd].univ = boolean(val);
        break;
      }
      continue;
    }
    if (row.contains("wait")) {
      delay(int(row.substring(5, row.length()))); 
      continue;
    }
  }
  return 0;
}
int searchVar(String name) {
  for (int i = 0; i < variables.length; i++) {
    if (variables[i] == null) break;
    if (variables[i].name == name) return i;
  }
  return -1;
}

When I close the main window, the program execution doesn`t stop, the program still endlessly prints hello world with this program code:

print Hello World!
wait 1000
goto 0

I think the solution would be to detect if the main window closes and then end the program. How?

Sorry, I’ve already found the answer. I`ll put it here if anyone needs it. It also works when the window is closed on X
