Usage of boolean in java
In Java, boolean is a basic data type with only two possible values: true and false. The boolean type is often used for conditional testing, such as comparison or checking whether a certain condition is met. If you want to know more about boolean in Java, you can read the article below this topic.
What is the difference between Boolean and boolean in JavaPreface 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.
