Question

I have the following codes for a button to get my group:

char group = 0;

if (Integer.parseInt(lblTbt.getText()) <= 30) {
    group = 'A';
} else if (Integer.parseInt(lblTbt.getText()) <=60) {
    group = 'B';

lblGroup.setText(String.valueOf(group));

but in another button I’m want to get a decimal value.

I try with the same code but with error.

double rf = 0;

if (Integer.parseInt(lblSurface.getText()) <= 29) {
   rf = '1.1';
} else if (Integer.parseInt(lblSurface.getText()) <=59) {
    rf = '1.3';

lblRF.setText(String.valueOf(RF));

I wanted to get the rf (decimal value) and setText into a label.

Any help will be appreciate

Answer 1

You need to change: rf = '1.1'; into: rf = 1.1;

Also, probably you will need: lblRF.setText(String.valueOf(rf)); instead of using RF
