Calling a static method from other class Android Java

How to call a method from MainActivity? The called method is static in another class. This code works perfectly fine on PC but fails on Android.

Here is the MainActivity code:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }

Metode.getDatum();
}

The other public class Metode, has a static method getDatum().

public static String getDatum() {

    Calendar koledar = Calendar.getInstance();

    int[] datum = new int[3];

    datum[0] = koledar.get(Calendar.DAY_OF_MONTH);
    datum[1] = koledar.get(Calendar.MONTH);
    datum[2] = koledar.get(Calendar.YEAR);

    String datumString = Arrays.toString(datum);

    return datumString;
}

I get "Identifier expected" after this token error.

This app has only one activity, the Metode class is 

public class Metode

Well, it looks like there was a problem in package declaration.

****package com.example.sluzba;****



import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.util.Arrays;
import java.util.Calendar;
import java.util.Scanner;


public class Metode {

public static String getDatum() {

Calendar koledar = Calendar.getInstance();

int[] datum = new int[3];

datum[0] = koledar.get(Calendar.DAY_OF_MONTH);
datum[1] = koledar.get(Calendar.MONTH);
datum[2] = koledar.get(Calendar.YEAR);

String datumString = Arrays.toString(datum);

return datumString;

}

Now it runs, if I call it from other method.

So I guess, package declaration (correct me if naming isn't correct) is important. Just saying, if a n00b like me gets into the same lamery. Thank you, everyone!!! Kao and others. Cheers!

This code isn't supposed to work. You have to call Metode.getDatum(); from other method.

Moreover, this method returns a String which is totally ignored. Probably you want use this somwhere?
