Analyze the following code:

```
public class Test1 {
public static void main(String[] args) {
xMethod(new double[]{3, 3});
xMethod(new double[5]);
xMethod(new double[3]{1, 2, 3});
}

public static void xMethod(double[] a) {
System.out.println(a.length);
}
}
```
a. The program has a compile error because xMethod(new double[]{3, 3}) is incorrect.
b. The program has a compile error because xMethod(new double[5]) is incorrect.
c. The program has a compile error because xMethod(new double[3]{1, 2, 3}) is incorrect.
d. The program has a runtime error because a is null.

c. The program has a compile error because xMethod(new double[3]{1, 2, 3}) is incorrect.
new double[3]{1, 2, 3} should be replaced by new double[]{1, 2, 3}) (anonymous array).
