getting value from textfield

[Arunesh]

At the time of press of ok button in the main menu i have created textfield in form called

"RequestIndent" like this ..

TextField text = new TextField(menu_item[i], null, 32, TextField.ANY);
RequestIndent.append(text);

now in form "RequestIndent" i have to fetch all the values put in all the textfields , but i am

not able to do so , if i would be able to create dynamic objects some thing like this my problem

would have been solved

TextField text[i] = new TextField(menu_item[i], null, 32, TextField.ANY);
RequestIndent.append(text);

i would have fetched values something like this

String value = text[i].getString();

but jave does not supports creating objects dynamically , hence i am not able to get the values

in all the textfields , kindly help to solve this problem

thanks and regards

Yes it does. Java only supports dynamic object creation. You're creating them dynamically either way. There's nothing to stop you holding the references to the objects in an array.

Hi,

You can definitely fetch the values from TextFields on the button pressed event. Can you put in the code and where you are getting the problem? You can have an array of TextFields and initialize them when you want or on particular button press event.

when i am writing this code it is working fine

for(int i = 1;i<=menu_item.length-1;i++)
{

System.out.println("menu appended at "+i+" place");
/*text[i] = new TextField(menu_item[i], null, 32, TextField.ANY);
RequestIndent.append(text[i]);*/

TextField tex = new TextField(menu_item[i], null, 32, TextField.ANY);
RequestIndent.append(tex);


}
but when i am writing this code i am getting null pointer exception

for(int i = 1;i<=menu_item.length-1;i++)
{

System.out.println("menu appended at "+i+" place");
text[i] = new TextField(menu_item[i], null, 32, TextField.ANY);
RequestIndent.append(text[i]);



}

while this has been defined at the start of application like this

TextField[] text;

pls help me solve the problem

thanks and regards

If you want an array, you need to create one.

TextField[] text = new TextField[ARRAY_SIZE];

You might want to do some reading to get up to speed on basic Java.
