"Is-A" refers to the "one" of one class and belongs to another class, while "Has-A" is different, which indicates that a certain role has a certain responsibility. A common reason for the wrong use of inheritance instead of aggregation is to mistakenly treat "Has-A" as "Is-A". For example:

"Er... I really can't remember the model, it's green, probably so thick." Wang Zeduan could not remember the specific model of the explosive cylinder, Just said the color and gesticulated the approximate size with his hand, Later, I looked up the information and learned that The detonators used at position 142 were all Type 68 detonators, This is also a classic explosive barrel widely used throughout the Sino-Vietnamese border war. This type of explosive cylinder is 60 centimeters long each, As long as there is a need, it can be spliced indefinitely. The charge for each section is 2.2 kg, According to Wang Zeduan's description, At that time, the explosive barrel was made up of three sections. Then the total charge is as high as 6.6 kg, However, the high explosive bomb used in the type 66 152 mm howitzer, The charge is 6 kg, In other words, The charge of these three explosive cylinders is 0.6 kg higher than that of a 152 mm grenade. This is also basically in line with his description that it is more powerful than a shell. In addition, after being inserted into the ground, the two sections of the upper half form a certain blast height from the ground, In this way, the explosive power can be better exerted virtually to cover a wider area, so it is indeed reasonable that an explosive barrel can successfully achieve the tactical purpose of successfully clearing position 142 for the second time (the first clearance is 66-type directional anti-infantry mines and 72-type pressure/tripping anti-infantry mines).
