hi, I have an array of about 50 textfields which show up when somebody presses button. Now I want to get the text from all the textfields using array....this is impossible the other way becouse then the program will become rigid....so I want to know how can I use getText() with array. eg.

for(int i=0;i<30;i++) { value[i]=text[i].getText(); }

//here value is an array. //text is the object(array) of textfield.
