how to use frida to reflect a method

[zxhubo]

For example, a java function

public byte[] aesEncrypt(String plaintext)

I want to reflect this method,

 var class_name1 = "com.example.cryptutils.util.CryptoUtils";
  var Platform1  = Java.use(class_name1);
var method = Platform1.getDeclaredMethod("aesEncrypt",XXXXX);

how to input the XXXX ?
