prompter: Can you look for errors in this Java Code?
```java
    public int test(String name) {
        String name = "Hello $NAME$ how are you doing?";
        name.replace("$NAME$", name)
        return name;
    }
``` assistant: Yes, there are some errors in the code. Firstly, the parameter 'name' is declared twice. This can cause confusion in the code and should be avoided. Secondly, the '.replace()' method should be assigned to the 'name' variable to store the result. So the code should look like this:

```java
public int test(String name) {
    String message = "Hello $NAME$ how are you doing?";
    name = message.replace("$NAME$", name);
    return name;
}
``` prompter: thanks assistant: No problem, let me know if you need any more help.
prompter: Could the function directly return the message instead of assigning it to name?
