previous value of same variable

How can I compare previous value of same variable(result) with current value.
Example, result 1 > result 2 or not, result 2 > result 3 or not, result 3 > result 4 or not, result 4 > result 5 or not.

Code :

---

import java.util.Random;
public class Test {
    public static void main(String args[]){
        double A = 5;
        Test Cal = new Test();
        Cal.run(A);        
    }
    void run(double A){
        Random random = new Random();
        double result;
        int i = 0;
        do{
           i++;
                result = A + random.nextGaussian() / 2;
                System.out.println(result);
        }while(i<5);           
    }
}

Keep track of the previous result in a temporary variable.

Example work-flow:

Init. 2 variables, last val and current val.

Get current val, set last val equal to current val.
for i = 1, i < 5, ++i
get a new current val
compare it to the last val
set last val equal to current val

Perfect work-flow.
I understand and can do it.
Thank you very much for your help.
