Data type:The Java language is a strongly typed language that defines specific data types for each type of data, and allocates a different size of memory space in memoryClassification of data types:Basic data type:Integer:Number of bytes occupied

Today just class, Yang teacher said the conversion between the system: 16 binary: 1,2,3,4,5,6,7,8,9,a,b,c,d,e,f. Already mastered, just a stroke!decimal integers, such as: 99,-500, 0octal integers, which require starting with 0, such as: 0

Java is divided into two types of data, one is the basic data type, one is the reference data type;Basic data types include Byte/short/int/long (4 integers), float/double (2 floating-point types), char (1-character), Boolean (1-Boolean)Reference

Data Typein a Java virtual machine, a data type can be divided into two categories: the base type and the reference type. A variable of the underlying type holds the original value, that is, the value he represents is the value itself, whereas a
