java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.Boolean.booleanValue()' on a null object reference

This error message indicates that your code is trying to call the booleanValue() method on a null object. This typically happens when you try to access a variable or object that has not been initialized or has been set to null.

To fix this error, you need to check if the object is null before calling any methods on it. You can use an if statement or a try-catch block to handle null values.

For example, instead of calling booleanValue() directly on a Boolean object, you can check if the object is null first:

Boolean myBoolean = null;
if (myBoolean != null) {
    boolean value = myBoolean.booleanValue();
    // do something with the boolean value
} else {
    // handle null case
}

Alternatively, you can use a try-catch block to catch the NullPointerException:

Boolean myBoolean = null;
try {
    boolean value = myBoolean.booleanValue();
    // do something with the boolean value
} catch (NullPointerException e) {
    // handle null case
}
