Method is not executed

I am trying to grasp a basic Java concept and I cant figure out why my method is not get executed. I would like to print out substring from word bunny if it has more than 3 characters, else print out the original string. My code:

package com.company;

public class Main {

    static String bunny = "bunny";

    public static String subStringBunny(String bunny) {
        if (bunny.length() > 3) {
            bunny = bunny.substring(2, 4);
        }
        return bunny;
    }

    public static void main(String[] args) {
        System.out.println("this is substring from bunny: " + bunny);
    }
}

It still prints the original string so I suppose the subStringBunny method does not get executed. Any help would be greatly appreciated! Thanks!

You're not calling subStringBunny method from the main method. This code should do what you're trying to achieve:

package com.company;
public class Main {    
    static String bunny = "bunny";    
    public static String subStringBunny (String bunny) {
        if (bunny.length() > 3) {
            bunny =  bunny.substring(2,4);
        }    
        return bunny;
    }

    public static void main(String[] args) {    
        System.out.println("this is substring from bunny: " + Main.subStringBunny(bunny));
    }
}

You're not calling the method. You most do this:

System.out.println("this is substring from bunny: " + subStringBunny(bunny));
