[BigData] Java constructor using the base _

Description of Requirement

 

 The figure needs to achieve, according to three people entered information, respectively, to calculate the average of three customers and maximum ages

Involving knowledge points:

① constructor

② string cutting

③ array of objects

Code

FIG code structure:

 

package cn.test.logan.day03;

public class Person {
    
    String custNo;
    String custName;
    int age;
    String addr;
    
    // define a constructor method: execution logic to initialize an object constructing 
    public the Person (Custno String, String custName, int Age, String addr) {
         the this .custNo = Custno;
         the this .custName = custName;
         the this .age = Age;
         the this .addr = addr;
    }
}

        }
        System.out.println ( "The average age was:" + AVG);
        System.out.println ( "maximum age:" + tmp);
