The problem encountered this time is still the jar package conflict encountered problems, resulting in the jar package class conflicts so that the method error,java.lang.NoSuchMethodError.The solution also begins to isolate the jar package, decompile the contents of the jar package and other jar package pairs. It's all in the eye. If there's MAVEN, it's not going to be so much, but.Another line of projects, the migration to MAVEN can not guarantee that there will not be any moth, it can only be

The reason why the wild pointer is produced:1, the pointer variable and the memory space variable that he points to are two different concepts2, although the call to the free (p) method frees the memory space pointed to by the pointer, but the pointer variable is not reset to null3, resulting in the freed of the pointed memory space, the use if (p! = NULL) is also executed, and the free () method is executedAvoidance methods:1, when the pointer is defined, initializes its value to null (char *p
The function of the application memory space in the C language malloc ()char *p = NULL;p = (char *) malloc (sizeof (char) * 100);The meaning of the above code is:Defines a char-type pointer pAllocate size to the memory space pointed by the pointer p through the MALLOC functionP is the memory addresssizeof is the number of bytes occupied by getting char, typically 4 bytesThe malloc function is the void* function (void * __cdecl malloc (_in_ _crt_guardoverflow size_t _size);)So to force the defini

Introduction to the upper function in Oracle
Upper ()
Converts lowercase letters in a string to uppercase letters.
Syntax upper (string)
String: string that converts lowercase letters to uppercase letters.
If the function is successfully executed, a string after converting lowercase letters to uppercase letters is returned. If an error occurs, an empty string ("") is returned ("").
If the value of the string parameter is null, the upper () function returns NULL.
For example:

This error message occurred today when installing SSH with the Apt-get directory under Ubuntu 14.04. Find out what might be the cause.First, APT acts as a software update mechanism that locks the apt database every time it runs. When the above error message occurs, you should first find out which process is running the apt-get or APT command, such as system updates.There are many ways to solve this problem.First of all, you did not find out exactly which process is using the APT command, then yo
