Penting untuk menentukan tegangan geser kritis berdasarkan jenis sambungan dan rasio aspek pelat persegi panjang.
Mari kita mulai dengan menyiapkan antarmuka, dan kami akan menggunakan Scene Builder untuk membantu.
Mari buat ruang kerja dengan ukuran 900x600.
Mari buat beberapa wadah dengan ukuran dan margin (awalnya saya melakukan markup hanya pada selembar kertas, tetapi potongannya sudah hilang).
Selanjutnya, mari kita lihat bagian dalam container.
- Tombol Tombol
Mari kita tetapkan nama unik untuk tombol kita dan nama metode di mana kita akan mengimplementasikan kode kita
- BidangTeks
Mari beri nama unik pada bidang teks kita. Bidang ini diperlukan untuk masukan / keluaran nilai numerik. Kami juga akan menambahkan nama tambahan ke bidang, yang akan hilang saat dimasukkan oleh simbol
-
Bidang Label Saya menggunakan bidang Label untuk menunjukkan sel.
- Bidang gambar
Di sini kami menentukan nama gambar yang ada yang terletak di proyek
- Bidang Kotak Centang
Di sini kami menentukan nama unik. Ini diperlukan untuk menentukan jenis pengikat

}Pembuatan dua kelas untuk menerapkan filter masukan data (Tidak termasuk huruf, serta kemampuan untuk membatasi jumlah masukan / keluaran). Solusinya bukan milik saya, tetapi saya menemukannya di stackoverflow. Dari semua yang diusulkan, menurut saya ini yang paling sederhana dan paling mudah dimengerti.
Kelas AlphaNumericTextFormatter
Kelas AlphaNumericTextFormatter
public class AlphaNumericTextFormatter extends TextFormatter<String> {
/** The Constant ALPHA_NUMERIC_ONLY. */
//private static final String ALPHA_NUMERIC_ONLY = "^[a-zA-Z0-9]*$";
/** MAKE NUMERIC ONLY **/
private static final String DIGITS_ONLY = "^[0-9.]*$";
/**
* Instantiates a new alpha numeric text formatter.
*/
public AlphaNumericTextFormatter() {
super(applyFilter(null));
}
/**
* Instantiates a new alpha numeric text formatter.
*
* @param maxLength
* the max length
*/
public AlphaNumericTextFormatter(int maxLength) {
super(applyFilter(new MaxLengthTextFormatter(maxLength).getFilter()));
}
/**
* Apply filter.
*
* @param filter
* the filter
* @return the unary operator
*/
private static UnaryOperator<Change> applyFilter(UnaryOperator<Change> filter) {
return change -> {
if (change.getControlNewText() != null && change.getControlNewText().matches(DIGITS_ONLY)) {
if (filter != null) {
filter.apply(change);
}
return change;
}
return null;
};
}

Itu saja. Sekarang file sudah siap yang akan berjalan di komputer manapun dengan java diinstal.
