, Boolean.② non-basic variables.Instead of the basic variable is the reference pass, the basic variable is the value pass!What about that? Should we write a wrapper of Char, Byte, short, int, long, float, double, and Boolean to wrap them into classes? But that's the way it is! But we don't have to write on our own, Java itself with these packages, is these basic types of packaging Class! Corresponding to the above basic variable type are:Character,Byte, short,Integer,long,Float,Double,Boolean.an

Packing and unpacking: any value type and reference type can be converted to the object type. Boxing conversion refers to implicit or explicit conversion of a value type into an object type, or convert the value type to an interface-type applied to the value type ). To pack a value of the value type, create an object instance and copy the value to the object. The data in the packed object is in the heap, and the address in the heap is in the stack. Th

"Pack/Unpack"when you need to add a value to a map, it is inconvenient to have the new object come out and the output to be forced type conversion.The use of the map interface in JDK1.5 provides a new mechanism. Automatic packing/unpack at the right time (only after JDK1.5)"Program Analysis"Note: This can be written after JDK1.5:M1.put ("One", 1);//Thrown in is still an object, but internally converted to int type M2.containvalue (1);int i = (Integer) m1.get ();//coercion type conversion integ

Packing classEverything in Java is an object, so many operations are for objects, and Java will automatically wrap the usual data types into objects of the corresponding classes.Support for automatic package and unpacking after jdk1.5Wrapper classes for common data typesPackingBoxing is the object that changes the base data type to the corresponding class.listnew ArrayList();//list的各种操作都是针对对象的list.add(5);//5本来是int类型的，现在自动包装成了Integer类的对象UnpackingUnpacking is to change the object of the correspond
