introduction to object oriented programming with java answers

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

Each of these values occupies two bits, which is less than two 0. such as "00:01:22". Note that the colon is in Latin, not Chinese.

attributes of the person class, define the name of this attribute we can write asString name;People have activities, such as talking, talking this behavior is the method in the above statement, the definition of a conversation this method can be written asvoid Talk () {method Body}The method body is the specific execution process that describes the behavior of the conversation.　　Ii. Creation of objects　The person class is created so that we can use it to create an

the system is large, it is often necessary to determine whether an object is created by a class. This can be accomplished using the INSTANCEOF keyword. The instanceof keyword can examine the type of an object, determine whether an object is an instance of a particular class, inherit from a class, or implement an interface. Use the following:$var instanceof class

must have a unique formal parameter list to distinguish it from other constructors.When you create a new object, Object Nn=new object (), where parentheses are called constructors.If we write a class, but no constructors are added to the class, the compiler adds a default parameterless constructor to the class. When an objec
