How to set a value for jspinner in java?

@jeanie_reilly 

To set a value for a JSpinner in Java, you can use the setValue() method of the JSpinner class. The setValue() method takes an Object as an argument, which should be the value you want to set the JSpinner to. For example:

1
2

JSpinner mySpinner = new JSpinner();
mySpinner.setValue(5);

This sets the value of the JSpinner to 5.

Alternatively, you can also use the setModel() method of the JSpinner class to set the value. This method takes a SpinnerModel as an argument, which can be an instance of one of the subclasses of SpinnerModel such as SpinnerNumberModel, SpinnerListModel, or SpinnerDateModel. For example:

1
2

SpinnerNumberModel model = new SpinnerNumberModel(5, 0, 10, 1);
mySpinner.setModel(model);

This sets the minimum value to 0, maximum value to 10 and step size to 1 and value to 5.

Please note that the setValue() method can also accept a null value, so make sure to handle any potential NullPointerException if necessary.
