The provided code has a few errors. The correct code should be:

```java
package q22488;

import java.util.Scanner;

public class TernaryOperator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);

int num1 = scanner.nextInt();
int num2 = scanner.nextInt();

String result = (num1 num2) ? "Greater than" : (num1 == num2) ? "Equal to" : "Less than";

System.out.println("First number is " + result + " second number");

scanner.close();
}
}
```

Here's the step-by-step explanation:

1. We first import the Scanner class from the java.util package. This class is used to get user input.

2. We then declare the main method, which is the entry point for any Java program.

3. Inside the main method, we create a Scanner object to read the user input.

4. We use the `nextInt` method of the Scanner object to read two integers from the user.

5. We then use a nested ternary operator to compare the two numbers. The ternary operator is a shorthand for an if-else statement and is written as `condition ? value_if_true : value_if_false`. In this case, we first check if `num1` is greater than `num2`. If it is, we set `result` to "Greater than". If it's not, we check if `num1` is equal to `num2`. If it is, we set `result` to "Equal to". If it's not, we set `result` to "Less than".

6. Finally, we print the result and close the Scanner object.
