Having issues in JAVA.

I have the following statements:

public class Faculty
{

private static final String[] researchArea1 = new String[3];
private Staff departments;
private Zeller birthday;
private Person countryOfBirth;
private Person name;
private Employee EmployeeID;
private Employee yearsOfService;

  
public static String[] researchArea1()
{
String[] researchArea1 = new String[3];

researchArea1[0] = "physics";
researchArea1[1] = "math";
researchArea1[2] = "compsci";

for (String str : researchArea1) {
System.out.println(str);
}
return researchArea1;

}

I just want to print them by how i choose so if i do print researcharea1[2] i want "compsci" to print. Though I'm getting so many issues with this. Can someone help me right a print method for this?

Also--- is there a way to check say if someone entered " english"

to throw a null or a print statement that says "wrong department"?

Thanks!
