java basic data typesThe basic data types of Java are: 1. byte, used to process byte-level data such as files and network transmissions; 2. short, which can be used to save memory space; 3. int, the most widely used integer type; 4. long, used to handle integer calculations that require larger values; 5. float, used for scientific calculations and scenarios that require high-precision calculations; 6. double, the most widely used floating point number type; 7. char, which can represent any character; 8. boolean, used for conditional judgment and Boolean operations.
How to convert between Java basic data types1. Automatic type conversion 1. Define the Java program to automatically convert small precision into large precision when performing assignment or operation. 2. Data types are sorted by precision: char—>int—>long—>float—>doublebyte—>short—>int—>long—>float—>double 3. There are many details for use
The length of java basic data typesThe maximum and minimum limits of Java's basic data types can be easily known by writing a small program. Test the maximum and minimum values of Integer, Long, Float and Double. The code is as follows: public static void main(String[] args) { System.out.println("Integer.MIN_VALUE = " + Integer.MIN_V ...
