How to limit the values in a Number JSpinner Component with Java?
To limit the values in a number JSpinner component, use the SpinnerNumberModel that allows to set the min, max, step size and even the initial value −
value − current value of the model min − first number in the sequence max − last number in the sequence stepSize − difference between elements of the sequence
Let us set the above values −
int min = 0; int max = 10; int step = 1; int i = 1; SpinnerModel value = new SpinnerNumberModel(i, min, max, step);
Now, we will set these values to our JSpinner −
JSpinner spinner = new JSpinner(value);
The following is an example to limit the values in a number JSpinner component −
Example
package my;
import java.awt.GridBagLayout;
import javax.swing.*;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame("Spinner Demo");
JPanel panel = new JPanel();
JLabel label = new JLabel("Rank − ");
panel.setLayout(new GridBagLayout());
int min = 0;
int max = 10;
int step = 1;
int i = 1;
SpinnerModel value = new SpinnerNumberModel(i, min, max, step);
JSpinner spinner = new JSpinner(value);
spinner.setBounds(50, 80, 70, 100);
panel.add(label);
panel.add(spinner);
frame.add(panel);
frame.setSize(550,300);
frame.setVisible(true);
}
}This will produce the following output −
