Java (maths) error? How to solve?

Question

Hi, here is some of my code,
public static void main(String [] args)
int num1;
int num2;
int num3;
num1 = 3;
num2 = 3;
num3 = 3;
if ((num1 == num2) && (num1 == num3))
System.out.println("Your triangle is equalateral, all sides are the same length!");
if (((num1 == num2) && (num1 != num3)) || ((num1 == num3) && (num1 != num2)) || ((num2 == num3) && (num2 != num1)));
System.out.println("Your triangle is isosceles, two sides are the same length!");
if ((num1 != num2) && (num1 != num3) && (num2 != num3));
System.out.println ("Your triangle is scalene, no sides are the same length!");
if ((((num1 num2)<num3) || ((num2 num3)<num1) || ((num1 num3)<num2)));
System.out.println ("Your 'triangle' isn't a triangle!");
I keep getting error with just this 1 line?
if ((((num1 num2)<num3) || ((num2 num3)<num1) || ((num1 num3)<num2)));
I do not know why, JavaBeans says "illegal start of expression"
Please can someone help? Thank you.

FYI another way to write this could be:
int equalsSides = (num1 == num2 ? 1 : 0) +
        (num1 == num3 ? 1 : 0) +
        (num2 == num3 ? 1 : 0);
switch (equalsSides) {
    case 3:
        System.out.println("Your triangle is equilateral, all sides are the same length!");
        break;
    case 2:
        System.out.println("Your triangle is isosceles, two sides are the same length!");
        break;
    default:
        System.out.println("Your triangle is scalene, no sides are the same length!");
}
