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;
    }
```
Yes, I can help with that. The code appears to be trying to replace the string "$NAME$" in the name variable with the value of the name variable itself. However, since name is a String and not a variable, it does not have a dollar sign ($) at the end, which causes an error. You should change the line to:

```java
    public int test(String name) {
        String name = "Hello $NAME";
        name.replace("$NAME$", name);
        return name;
    }
```

This will fix the problem by ensuring that the replacement occurs on the correct portion of the string.
