How to do that static method will remember and work result from previous method

I'm beginner and I am creating my first game ever,but in Main class I made code for 600 lines a I want to clean it.I did methods in another classes,but static methods can't work with result from previous method.I'm from Czech republic,so next to is translate for help.I've translated just phew,but sometimes are words repeating.

public static void VyberKone() {//method of choosing horse
    Scanner sc = new Scanner(System.in);
    int penize = 1000;
    System.out.println("A jak se bude jmenovat?");//Give name to your Horse
    String jmenoKone;//name 
    jmenoKone = sc.nextLine();
    int volbaKone = Integer.parseInt(sc.nextLine());//choose of horse by 1-3
    Kun vyber = null; //choose of horse

    switch(volbaKone) {
        case 1:
            System.out.println("Vybral sis stepního plnokrevníka");//You've choose this horse
            Kun plnokrevnik = new Kun(jmenoKone,"stepní plnokrevník",88);//horse
            vyber = plnokrevnik;//choose = type of horse
            penize = penize - 80;//money 
            System.out.println("Zůstalo ti:" + penize);//residue of money
            break;
