7-1 Student Class-constructors

Defines a student class for students, containing class member variables: string name, string sex, int age, and all variables must be private.

1. Write the parameter constructor:

Can assign values to name,sex,age.

2. Overwrite the ToString function:

By format: class name [Name=, sex=, age=] output. Automatically generated using idea, and then modified to the output format

In the 3.main method

Enter 1 lines name age sex, call the above parameter constructor to create a new object.

Input Sample:

Tom Male

Sample output:

Student [name= ' Tom ', sex= ' male ', age=15]

7-2 Defining classes

Please add the following code to complete the output requirements.

1 Import Java.util.Scanner; 2 public class Main {3 publicly     static void main (string[] args) {4                 Scanner in = new Scanner (system.in); 5                 int A,b,c,d,e; 6                 a = In.nextint (), 7                 B = In.nextint (), 8                 c = In.nextint (), 9                 d = In.nextint (), and                 e = In.nextint (); RR                 rr = new RR (),                 double dd = rr.fun (a,b,c,d,e)                 , System.out.printf ("%.2f", DD),     }15}16 Class rr{17 18 19}

7-3 Horizontal Flat Vertical

Procedural blanks. Refine the code below as required by the topic. Please submit the full code. If the height of a block is larger than the width, we say it is upright, otherwise we say it is flat. Read into the height and width of a block of wood. If it is flat, then output a, otherwise output B.

1 Import Java.util.Scanner; 2 public class main{3 public     static void Main (string[] args) {4         Scanner in = new Scanner (system.in); 5         int he ight, Width; 6         char status; 7         height = in.nextint (); 8         width = In.nextint (); 9         Board Board = new Board (height, width); 1 0         status = Board.getstatus ();         System.out.print (status)     ,}13}14 class board{15    int height, width ; public    Board (int height, int width) {        this.height = height;18        this.width = width;19    }20    Public Char getStatus () {        if (height<=width) {[           1];        }else{24          return status ( 1.0);        }26    }27 public    char status (double rate) {     32}-Public     char status (int rate) {31     

Input format:

The input gives 2 positive integers a and B with an absolute value not exceeding 1000 in a row.

Output format:

Outputs a character A or b in a row.

Input Sample:

50 50

Output sample :

A

7-4 procedure to change the wrong question

The program changes the wrong question. There is an error in the following code, please submit it after modification.

1 public class Main {2 public     static void Main (string[] args) {3         Animal Animal = new Dog (); 4         animal.shout () ; 5         Animal.run (); 6     } 7} 8  9 class Animal {Ten     void shout () {         System.out.println ("Animal shout! "),     }13}14 class Dog extends Animal {     void shout () {         super.shout ();         System.out.println (" Wangwang ... ");     }20     void Run () {         System.out.println (" Dog is Running ");     

Sample output:

Animal shout!

Wangwang ...

Dog is running
