setting jTextField values dynamically

Question

First, I'm new to java. Lately encountered a problem like this.

I have an integer array like,

 int[] data={32,12,31,89,90};

then, I have 5 jTextFields.

I named them as jNum0,jNum1,...,jNum4. Problem is that according to the program I'm working on

I need to print each value in array in respective textbox by using a loop .

Like:

for(int i=0;i<=4;i++){ 
//<jNum+i>.setText(data[i]);
// This actually doesn't work
}

Is there a way to do this?

Answer 1

Better create an 'array of TextField'

TextField tf[] = new TextField[5];

And after this, call for loop as

for(int i=0;i<=4;i++)
{
     tf[i].setText(data[i]);
}

It will work.

Answer 2

Try to solve by creating an array of JTextFields and refer each JTextField by its index. You will be able to access each JTextField by its index and your problem would be solved.

jTexts are just classes and like any other class in Java you can easily create an array of objects of type jText.

Answer 3

You have hata in array. Put jTextFields in array too.

JTextField[] fields = new JTextField[5];
for(int i = 0; i < fields.length; i++) {
    fields[i] = new JTextField();
}

for(int i = 0; i < fields.length; i++) {
    fields[i].setText(data[i]);
}
