シンプルなGUIで作業していて、テキストフィールドで苦労しています。
これは私が取り組んでいるものです。右は見た目、左は私がやったものです。住所1、住所2などのラベルを付けることに成功しました。しかし、テキストフィールドを付け始めると、ラベルが消えました。setSize、setLocationを使用してみましたが、何も機能しません。
期待される結果に見られるように、同じことが上部パネルの「PaymenMethod」にも起こっています。テキストフィールドがあるはずです。コードにそれらが含まれていますが、実行時に表示されません。助けてください。
これが私のコードです：
import javax.swing.*;
import java.awt.*;

public static void main(String[] args){
//Frame

contentPane.setSize(300,350);
contentPane.setResizable(false);
contentPane.setLayout(new BorderLayout());
//Payment Panel
JPanel paymentPanel = new javax.swing.JPanel();
paymentPanel.setLayout(new BorderLayout());
//paymentPanel.setPreferredSize(new java.awt.Dimension(270, 90));
paymentPanel.setBorder(javax.swing.BorderFactory.createTitledBorder(null, "Payment Method", javax.swing.border.TitledBorder.DEFAULT_JUSTIFICATION, javax.swing.border.TitledBorder.DEFAULT_POSITION, new java.awt.Font("Arial", 1, 12)));
