Java method argument return value

Prerequisites/What you want to achieve

The variable int num is given an input value by the system.
A method is created, the method is called by main, and all elements of the return value are displayed.
At that time, processing is implemented so as not to display the 0th element.
Also, when the return value is null, the output is not the output of the element but "the specified ID cannot be found".
When calling a method, the real argument sets the variable int num.

Input values

1
2
3
4

Expectations

 Ayeo
kakikukeko
sasisuseso

Method Contents

{"1", "A", "I", "Ueo"}
{"2", "ka", "ki", "kakeko"}
{"3", "Sa", "Shi", "Sasiso"}

Declare three static array variables with the above elements.
A numeric type argument is converted into a String type variable.
A 0th value of each array is compared with an argument converted into a String type, and when the argument is compared and matched, the matched array variable is used as a return value.
If it does not match any array, null is the return value.

Problems/Error Messages you are experiencing

java.lang.NullPointerException

appears.
I think the reason is that there was no processing when null was returned, but I looked into various things and wrote the code, but I couldn't process it well.
I would appreciate your advice.

import java.util.Scanner;
public class Main {
  public static void main(String[]args) {
    Scanner scan = new Scanner (System.in);
    String text = scan.next();
    int num = Integer.parseInt(text);
    String [ ] fuga = getUserProfile (num);
      for (inti=1; i<fuga.length;i++) {
        if(fuga[i]!=null){
          System.out.println(fuga[i]);
        } else {
          System.out.println("The specified ID is not found");
        }
      }

    String [ ] data1 = {"1", "A", "I", "Ueo";
    String [ ] data2 = {"2", "ka", "ki", "kakeko";
    String [ ] data3 = {"3", "sa", "sh", "sasu" };
    String hoge = Integer.toString(num);
      if(data1[0]==hoge){
        return data1;
      } else if(data2[0]==hoge){
        return data2;
      } else if(data3[0]==hoge){
        return data3;
      } else {
        return null;
      }
  }
