是否可以生成一个JTextField变量字符串

Question

我通过生成一些变量

        String[] StoreValueFromTable = new String[5];
        String[] ColumName = new String[5];
        for(int Count=0;Count<5;Count++){
            StoreValueFromTable[Count] = "QueryTechnica"+Count;
            ColumName[Count] = "QT"+Count;
            System.out.println(StoreValueFromTable[Count]+", "+ColumName[Count]);
        }

我正在尝试使JTextField[] Fiels[Count] = new JTextField();出错。我不确定，有没有一种方法可以使它动态。。

您可以这样做：

final int TEXTFIELDS_COUNT = 5; 
// Create an array of 5 JTextFields
JTextField[] fields = new JTextField[TEXTFIELDS_COUNT];
for(int count = 0; count< TEXTFIELDS_COUNT; count++){
    // fields[count] represents a single JTextField
    fields[count] = new JTextField();
    // Do something with fields[count], like setting its text 
    // fields[count].setText("some text");
    StoreValueFromTable[count] = "QueryTechnica"+count;
    ColumName[count] = "QT"+count;
    System.out.println(StoreValueFromTable[count]+", "+ColumName[count]);
}
