Assalamu'alaikum wr.wb.

Cara Membuat Persentase Data Korban Covid 19 Menggunakan Netbeans

1. Buatlah Project Baru Dengan Nama Kamu

2. Lalu Buatlah Package Dengan Nama UTS

3. Import Library JfreeChart

4. Buat JInternalFrame Dengan Nama Data

5. Lalu Desain Seperti Berikut

6. Masukan Source code Pada Button Simpan

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {

// TODO add your handling code here:

int a_YudiWahyudi, b_YudiWahyudi, c_YudiWahyudi, d_YudiWahyudi;

a_YudiWahyudi=Integer.parseInt(i1.getText());

b_YudiWahyudi=Integer.parseInt(i2.getText());

c_YudiWahyudi=Integer.parseInt(i3.getText());

d_YudiWahyudi=Integer.parseInt(i4.getText());

t1.setText(a_YudiWahyudi+" orang");

t2.setText(b_YudiWahyudi+" orang");

t3.setText(c_YudiWahyudi+" orang");

t4.setText(d_YudiWahyudi+" orang");

}

7. Masukkan Source code Pada Button Grafik

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {

// TODO add your handling code here:

DiagramPie obj1_YudiWahyudi = new DiagramPie();

obj1_YudiWahyudi.setNilai(i1.getText(),i2.getText(),i3.getText(),i4.getText());

obj1_YudiWahyudi.setVisible(true);

dispose();

}

8. Lalu Buatlah Java Class Dengan Nama DiagramPie

9. Masukkan Source code Pada Class DiagramPie
