Boolean method to check a random number

Question

I have a class that generates a random number within a given interval.

    public class Dice{
          //code.....

          public int throwDice(){
             Random randomGen = new Random();
             int min = 1;
             int max = sides; //sides gets a value earlier in the class
             int randomNum = randomGen.nextInt((max - min) + 1) + min;
             return randomNum;
          }

Then the assignment says that I'm going to use a boolean method that looks like this (with my already written code in it as well):

    private boolean step(){
        int res = this.dice.throwDice();
        int startpos = this.bridge.getFirst();
        if (res == 10){ //this works
            return false;
        }
        else if (res => 7 && res <= 9 ){ //but the error occurs here 
            //code....
            return true;
        }

What I need to do is check if the generated random number in the throwDice() method is within a certain interval of numbers.

The problem is that I get an error that says that I can't convert an int to a boolean . Is there a way to get around this? Or do I have to rethink my whole solution?

Answer 1

=> should be the other way around.

else if (res => 7 && res <= 9 ){

should be

else if (res >= 7 && res <= 9 ){
