Question

我试图制作3 JOptionPane。每个人都必须显示一些数据。

第一个必须显示firstDataArray的20个信息

只有当用户点击取消时我想要弹出新的JOptionPane，它必须显示secondDataArray等的信息......

我面临的问题是当用户点击第一个JOptionPane上的取消时，第二个JOptionPane显示firstDataArray和secondDataArray的所有信息（我想要2个分开） JOptionPane具有不同的数组列表）

当第二个JOptionPane的取消底部相同时，第三个JoptionPane显示3数据数组的所有信息

我做错了什么？

很多欣赏，

      String[] firstDataArray= new String[20];
            String[] secondDataArray= new String[20];
            String[] thirdDataArray= new String[20];

            firstDataArray= ClassA.getFirstData();
            secondDataArray= ClassA.getSecondData();
            thirdDataArray= ClassA.getThirdData();

            StringBuilder textRegion = new StringBuilder();

            String txt = JOptionPane.showInputDialog(null,
                    textRegion.append(Arrays.toString(firstDataArray).replace("[", "").replace("]", "").replace(",", "")).append('\n'), "Choose Option)",
                    JOptionPane.PLAIN_MESSAGE);
//If the user click cancel , show the other array in a new JoptionPane   
            if (txt == null) {

                txt = JOptionPane.showInputDialog(null,
                        textRegion.append(Arrays.toString(secondDataArray).replace("[", "").replace("]", "").replace(",", "")).append('\n'), "Choisir municipalite (Chose option)",
                        JOptionPane.PLAIN_MESSAGE);


//If the user click cancel again , show the other array in a third JoptionPane  
                    if (txt == null) {

                    txt = JOptionPane.showInputDialog(null,
                            textRegion.append(Arrays.toString(thirdDataArray).replace("[", "").replace("]", "").replace(",", "")).append('\n'), "Chose Option)",
                            JOptionPane.PLAIN_MESSAGE);
                    if (txt == null) {

                    } else {
                        setNomMunicipalite(txt);
                    }

                } else {
                    setNomMunicipalite(txt);
                }
            } else {
                setNomMunicipalite(txt);
            }

您始终将每个数组附加到相同的StringBuilder。

为每个JOptionPane

使用一个新的

        StringBuilder textRegion = new StringBuilder();

        String txt = JOptionPane.showInputDialog(null,
                textRegion.append(Arrays.toString(firstDataArray).replace("[", "").replace("]", "").replace(",", "")).append('\n'), "Choose Option)",
                JOptionPane.PLAIN_MESSAGE);
        //If the user click cancel , show the other array in a new JoptionPane   
        if (txt == null) {
            textRegion = new StringBuilder(); // <--- 
            txt = JOptionPane.showInputDialog(null,
                    textRegion.append(Arrays.toString(secondDataArray).replace("[", "").replace("]", "").replace(",", "")).append('\n'), "Choisir municipalite (Chose option)",
                    JOptionPane.PLAIN_MESSAGE);


                //If the user click cancel again , show the other array in a third JoptionPane  
                if (txt == null) {
                textRegion = new StringBuilder(); // <---

                txt = JOptionPane.showInputDialog(null,
                        textRegion.append(Arrays.toString(thirdDataArray).replace("[", "").replace("]", "").replace(",", "")).append('\n'), "Chose Option)",
                        JOptionPane.PLAIN_MESSAGE);
                if (txt == null) {

                } else {
                    setNomMunicipalite(txt);
                }

            } else {
                setNomMunicipalite(txt);
            }
        } else {
            setNomMunicipalite(txt);
        }

如何在单独的JOptionPane中显示不同的数组
