Char array Vs Byte array which one to use?

Vote count:

I was passing sensitive information (between my app and backend) like password in String format. Later on I realized that password can be easily read from heap memory dump as it is stored in text format.

String password = "super_password";

So I decided to use Char array,

Char[] passChar = password.toCharArray();

but I am worried that password can still be read from memory dump character by character. Then I thought of using byte array instead.

byte[] passByte = password.getBytes();

My question: Is it safe to use byte array for passing sensitive information like password ? OR can anyone recommend anything secure ?

Thanks in advance
