How to set a boolean value in Java to null?

In Java, a boolean variable can only have the values true or false, and cannot be set to null. If you need to represent an uninitialized or invalid state, you can use a Boolean object instead of the boolean type. A Boolean object can be set to null to represent an uninitialized or invalid state.

Here is an example code:

Boolean myBoolean = null; // 将Boolean对象设置为null

// 对Boolean对象进行判断
if (myBoolean == null) {
    System.out.println("Boolean对象未初始化");
} else {
    // 具体逻辑处理
}

When it is necessary to represent a boolean value that may be null, you can use the Boolean object instead of the boolean type.
