Parsing: CLR supports two types: Value Type and reference type. In the words of Jeffrey Richter (author of CLR via C #), "programmers who do not understand the differences between reference types and value types will introduce code into weird traps and many performance problems ". This requires us to correctly understand and use the value type and reference type.

1, Java in the "Basic type" and "basic type" comparison = = = Comparison is the value 2, the comparison of "basic type" and "reference type" in Java is also a comparison between the base type and the base type. Long j= 10000l; Long i= New Long (10000); System. Out. println (I==J); True So the reference type and the base type are compared, and when compiled into the underlying instruction, the reference type is converted to the base type and the value of the comparison. System. Out. println (K.

Method One: Using the Object.ToString () methodExample: Object object=getobject ();System.out.println (Object.ToString ());Note: If an object is null and is not instantiated, calling the method will report a null pointer exception Method Two: Use coercion type conversion, which is to cast (String) before objectExample: Object object=getobject ();System.out.println ((String) object);Note: Not all types can be cast to string type, preferably with insta

Label:In MySQL database system, char and varchar are very common, and they are two very similar, are used to save relatively short string, such as saving the article title, message, email, user name and so on. The main difference between the two is the storage method:The Char column length is the length that is declared when the table is created and is fixed, and the length is limited to between 0 and 255. Generally in the database design, the user to save passwords, names, IP information, becau

The type of a valueThe basic types and reference types are mentioned earlier in the introduction of the data types of JS, but before we can say two types, let's look at the type of the variable's value. In ECMAScript, a variable can have two types of values, namely the origi
