Default constructor generate two random equations

Need to create a default constructor in a programmer defined class that generates a random question, addition or subtraction. And when adding the numbers must be random from 0-12 and when subtracting the first number must be from 6-12, while the second is less than the first number. Here's my progress as of now:

```package project4;

public class Question {
private int num1;
private int num2;
private char operand;

public Question()
{
operand = '+';
num1 = (int)(Math.random())*12;
num2 = (int)(Math.random())*12;

operand = '-';
num1 = ((int)(Math.random())*12+6);
num2 = (int)(Math.random()) << num1;

}

public String toString()
{
String str = new String(num1 + " " + operand + " " + num2);
return str;
}
```

}

However when I call it in the application class like I did underneath, I get 6-0 please help.

```package project4;

public class Project4App
{
public static void main(String[] args)
{
Question question1 = new Question();
System.out.println(question1.toString());

}
}
```
