Creating an Algorithm in Java

Could you please help me solve this java algorithm?

the idea is to create a method that counts a number from -5 to 30 and then it goes down -1 till reaches -5 then starts again

for example method should return: -5, 0, 5, 10, 15, … , 25, 30, 29, 28, 27, … , -3, -4, -5, 0, 5,..

I have tried the following, but still I cant find a solution.

--

double a = -5;

 public double methodx(){

  boolean positiveDirection = true;

  if(positiveDirection == true) {

  if(a != 30) {

  a += 5 ;   
  positiveDirection=false;
  return a;    
} 
  else  {
  a -= 1;
  positiveDirection=false;  
}
}return a;

    public void counter(){
        int number = -5;
        int direction = 1; // -1 negDirection , +1 pos direction
        for (int i = 0; i < 100; i++) {
            System.out.print(String.valueOf(number) + ',');
            if (direction < 0) {
                number = number - 1;
                if (number == -5)
                    direction = +1;
            } else {
                direction = 1;
                number = number + 5;
                if (number == 30)
                    direction = -1;
            }
        }
}

You can convert 100 to any number you want

If you just want to print that numbers, you can try this
The loop variable indicates how many times you want to print that sequence of numbers

    public void methodx(){
    int loop = 2;
    while(loop != 0){
        for(int i = -5; i <= 30; i+=5){
            System.out.print(i + " ");
        }
        for(int i = 29; i >= -4; i--){
            System.out.print(i + " ");
        }
        loop--;
    }
}
