       String namamahasiswa=nmmahasiswa.getText();

       double nilaiabsen = Double.valueOf(absensi.getText());

       double nilaiuts = Double.valueOf(uts.getText());

       double nilaiuas = Double.valueOf(UAS.getText());  

       

       double nilaiakhir = (0.1 * nilaiabsen) + (0.4 * nilaiuts) + (0.5 * nilaiuas);

       char index =0;

       String statusa =" ";

       

       if(nilaiakhir >= 0 && nilaiakhir <= 49){

           index = 'E';

           statusa = "Tidak Lulus";

       }else if(nilaiakhir >= 50 && nilaiakhir <= 59){

           index = 'D';

           statusa = "Kurang";

       }else if(nilaiakhir >= 60 && nilaiakhir <= 69){

           index = 'C';

           statusa = "Cukup";           

       }else if(nilaiakhir >= 70 && nilaiakhir <= 79){

           index ='B';

           statusa ="Bagus";

       }else if(nilaiakhir >= 80 && nilaiakhir <= 100){

           index ='A';

           statusa ="Sangat Bagus";

       }else{

           index=0;

       }

           nama.setText("Nama Mahasiswa : "+namamahasiswa);

           nilai.setText("Nilai Rata-rata : "+nilaiakhir);

           grade.setText("Grade : "+index);

           status.setText("Status : "+statusa);     

    }       

the output project you can add the label on the panel "hasil" like this.
