I need to get the value of different text boxes.
I want to get the value of each one using a for loop or something like this:
txt0,txt1,txt2,txt3;
for(int i=0;i<4;i++){
String valor = (txt+i).getText();
}
There is a way to get the value by concatenating another value to the name of the textbox or any other object??
I don't know if you have access to the variables but you can use an array instead. This will make looping much easier.
TextBox[] text = {txt0, txt1, txt2, txt3};
for (TextBox txt : text) {
String valor = txt.getText();
}
I don't know if I have well understood your question so this might be a wild guess.
If you want to have all your text boxes fields concatenated value, You need to have a set that can hold all of their references and your main solution should be JAVA Collections API.
You need to store all of your JTextField objects references in a Collection (each time you construct a new one add it to the Collection), can be a List, Map or a Set, then iterate over that Collection once it is filled and build your concatenated String using their values (I would suggest to use a StringBuilder that the way you actually do it):
// Initialize your Collection, will be an ArrayList for this e.g.
List<JTextField> textFields = new ArrayList<JTextField>;
// Instantiation example, it should be done for all fields
JTextField txt0 = new JTextField(20);
textFields.add(txt0);
// Do the same for txt1, txt2 ...
// Iterate over your List to get the concatenated String
StringBuilder sBuilder = new StringBuilder();
for(JTextField textField : textFields){
sBuilder.append(textField.getText());
}
// Print your final value
System.out.print(sBuilder.toString());
