I need a simple Java program example that secures sensitive information. The secure example should use char arrays or the securestring class as is talked about in the below paragraph. It would be nice to have two examples ie an unsecure example and then a secure example.

Please and thank you

Sensitive data can be exposed when it is left in memory. In Java, objects are stored in the heap memory. If sensitive data like passwords, credit card numbers, etc., are stored in String objects, they will remain in the memory until garbage is collected, which can be an indefinite amount of time. During this time, a memory dump could expose this sensitive data. To mitigate this, one can use char arrays or the SecureString class, which allows for the data to be cleared from memory immediately after use.
