Speaking of String, everyone is m
want Masons silently for themselves, for the family for the future lay the groundwork. As you can see, string is a class that does not need to create a new object using new. It is immutable (Constant), and its value (like "ABC" is created, cannot be changed). Naturally, string actually implements the function of the sequence of the basic type char, so the Chinese name "string". Here it is possible to doubt that Mason will find the JDK source code evidence to show you: This code is from the JDK

To put it simply, Java divides memory into two types: stack memory and heap memory. Variables of some basic types defined in the function and referenced variables of the object are allocated in the function stack memory. When a variable is defined in a code block, Java allocates memory space for the variable in the stack. When the scope of the variable is exceeded, java
Java. util. Date: indicates the operation time:
Java. util. Date d1 = new java. util. Date (); // a time is created based on the current time.
Of course, you can also use another method: long times =System. currenttimemillis ();
Java. util. Date D2 = new date (times );

After learning the APIs for Java NIO and io, a problem immediately poured into my mind:When should I use IO and when do I use nio? In this article, i'll try to clearly parse the differences between Java NiO and io, their usage scenarios, and how they affect your code DESIGN.The main differences between Java NiO and IOThe following table summarizes the main differ

The current default directory is the Administrator folder under the C Disk Users folder. Generally speaking, we are accustomed to changing the current directory. Because Windows has a disk partition, to jump to another disk, such as e disk, there are several ways:
1. Input command: pushd path (This command can set the current directory to any existing path that you want)
