be told to the compiler in advance. The Java garbage collector will automatically collect the data that is no longer used. However, the slow access speed is due to the need to dynamically allocate memory during runtime. 3. There are two data types in Java.One is the basic type (primitive types). There are eight types, namely int, short, long, byte, float, double, Boolean, char (note, there is no basic

Strings are the most widely used data types in programming. They are simple and practical, but understanding them in depth will bring us more benefits. String cache pool: To save memory and improve resource reuse, Java introduces the String cache pool concept. Strings in the cache Pool cannot be recycled: Strings in the cache pool will not be recycled by the

Double Forcing data type conversionsThe format of the cast is to add "()" before the data that needs to be transformed, and then add the data type that needs to be converted in parentheses. Some data after transformation operation, the accuracy will be lost, and some will be more accurate, the following example can illustrate this problem. Public class Demo { public static void main(String[] args){ int x; double y

using XStream to convert between Java objects and XMLXStream is a good thing, easy to convert between Java objects and XML, efficiency and readability are very high, the following is a test example I wrote, let's take a look.
