you have to create four object "zerg"(zerg1, zerg2 ...) and name it (zerg1.name, zerg2.name...) etc....

The version below also works, although here the String Name variables are private. However, this is only because the Zerg, Protoss and Terran classes are inside the Solution class.

public class Solution {
    public static void main(String[] args) {

        Zerg zerg1 = new Zerg();
        zerg1.name = "LittleGrey1";

        Protoss protoss1 = new Protoss();
        protoss1.name = "Reptilian1";

        Terran terran1 = new Terran();
        terran1.name = "Bob";

        System.out.println(zerg1.name + " " + protoss1.name + " " + terran1.name);
    }

    public static class Zerg {
        private String name;
    }

    public static class Protoss {
        private String name;
    }

    public static class Terran {
        private String name;
    }
}

Normally, if they were separate classes, as below, it would not be possible to use the private variable of the Zerg class from the Solution class in this way:

public class Solution {
    public static void main(String[] args) {

        Zerg zerg1 = new Zerg();
        zerg1.name = "LittleGrey1"; // error: name has private access

        Protoss protoss1 = new Protoss();
        protoss1.name = "Reptilian1"; // error: name has private access

        Terran terran1 = new Terran();
        terran1.name = "Bob"; // error: name has private access

        System.out.println(zerg1.name + " " + protoss1.name + " " + terran1.name); // error: name has private access
    }
}

class Zerg {
    private String name;
}

class Protoss {
    private String name;
}

class Terran {
    private String name;
}

But if the variables are public in these separate classes, you can access/use them directly from the Solution class:

public class Solution {
    public static void main(String[] args) {

        Zerg zerg1 = new Zerg();
        zerg1.name = "LittleGrey1"; // it works

        Protoss protoss1 = new Protoss();
        protoss1.name = "Reptilian1"; // it works

        Terran terran1 = new Terran();
        terran1.name = "Bob"; // it works

        System.out.println(zerg1.name + " " + protoss1.name + " " + terran1.name);  // it works
    }
}

class Zerg {
    public String name;
}

class Protoss {
    public String name;
}

class Terran {
    public String name;
}
