        String nama = dataSiswa[0];
        String kimia = dataSiswa[1];
        String biologi = dataSiswa[2];
        String fisika = dataSiswa[3];

        data = "Nama: " + nama;
    }
    return data;
}

Answer

You were pretty close to it:

public static String dataSiswa(ArrayList<String[]> list_Siswa){

    String data = "";
    for (String[] dataSiswa : list_Siswa){
        data += "Nama: " + dataSiswa[0] + "n" +
                "Kimia" + dataSiswa[1] + "n" +
                "Biologi" + dataSiswa[2] + "n" +
                "Fisika" + dataSiswa[3] + "nn";
    }
    return data;
}

This generates your String to be outputted. Printing:

System.out.print(yourArrayList);

Just don’t forget to initialize yourArrayList prior of the method call.
