read the name "# # #" (three #), the city name entered the end, # # #并不是一个城市的名字. If the number of city names to be read is n.Then you will read an integer matrix of nxn. Each number in the first row represents the mileage between the first city in the list of cities and the other city in turn. The mileage between the same city in the table is 0.Finally, you will read the names of two cities.Output format:Output the distance between the two cities.Input Sample:HagzouHugzoujigxng # # # 01108708 1

Recently, read the Sun Weichen teacher's "Java Object-oriented programming" a book, the heart quite a bit of sentiment, thinking to record it down.Modifiers in JavaIn the Java language, there are some words (more accurately, it sh

"abstract Method" in Java is equivalent to the pure virtual function in C ++. 13. constructors do not have multi-state rows (they are actuallyStatic Method, But the static statement is implicit ). 14. If a dynamic binding method is called within the constructor, the member manipulated by the called method may not be initialized (It may cause some difficult-to-discover hidden errors.). Example: Class glyph {void draw () {system. out. println ("glyph
