JTextFields process
Please, help!
I have a problem and I can't resolve it. Maybe you can help me. I hope so.
I have 18 JTextFields and they have nearly alike name(txtA1, txtA2, txtA3, txtB1, txtB2...). So, I
want to do method to process them only have a part of name.
For example:
public String doJTextFields(String s){
...
ccc = (txt + s + 1).getText()
...
}
How to force compiler to understand that"(txt + s + 1)" means "txtA1" or "txtB1".

If you want to do this within a Java program, you can use java's Regular Expression capabilities, and use String.matches(regex) to match multiple names.The compiler doesn't have anything to do with this, the Java code you use is what matters.
One way to do this is to use a HashMap.JTextField jtf1 = new JTextField("1");
JTextField jtf2 = new JTextField("2");
JTextField jtf3 = new JTextField("3");
HashMap map = new HashMap();
String s = "jtf";
map.put(s+"1",jtf1);
map.put(s+"2",jtf2);
map.put(s+"3",jtf3);
JTextField get1 = (JTextField)map.get(s+"1");
JTextField get2 = (JTextField)map.get(s+"2");
JTextField get3 = (JTextField)map.get(s+"3");
System.out.println(get1.getText());
System.out.println(get2.getText());
System.out.println(get3.getText());
