What is the difference between Boolean and boolean in Java
Preface Someone asked, aren’t there only two types of Boolean values: true and false? Why does the attribute he defined have a null value? We should first make it clear that boolean is the basic data type of Java, and Boolean is a class of Java. The boolean type will assign false to the attribute during the "assign zero value" phase. Boolean is a class that will assign null to the object in the "assign zero value" phase. If it is a static property, it will be assigned when the class is loaded. If it is a normal class attribute, the value will be assigned when the object is instantiated. These two points can help you understand the "class loading mechanism" and "object creation process". Class loading mechanism: Loading: Get the binary byte stream of the class based on the full name of the class, and

How many bytes does the boolean type occupy in Java?
The boolean type in Java occupies bytes: 1. 1 bit. The reason is that the value of the boolean type only has two logical values: true and false. After compilation, it will be represented by 1 and 0; 2. 1 byte. The reason is that although After compilation, 1 and 0 only occupy 1 bit of space, but the smallest unit of data processed by the computer is 1 byte.

Java Boolean is how many bytes
The Boolean type in Java does not give a precise definition, but the "Java Virtual Machine Specification" gives the definition that the Boolean type is 4 bytes, and the Boolean array is 1 byte. The specific definition depends on the virtual machine. Whether the implementation follows the specification, so 1 byte and 4 bytes are both possible.
