Write a student class to input information and the age cannot be less than 16 years old
package com.bdqn.demo;
import java.util.Scanner;
public class Student1 {
private String name;//姓名
private int age;//age
public String getName() {//Return name
return name;
}
public void setName(String name) {//Specify name
this.name = name;
}
public int getAge() {//Return the age
return age;
}
public void setAge(int age) {//If the age is unreasonable, restore the default
if(age>15) {
this.age=age;
}else {
System.out.println("Error output! Restore default 16 years old");
this.age=16;
}
}
public void print() {//Output statement method
System.out.println("Hello everyone! My name is "+name+" this year is "+age+", thank you guys");
}
public static void main(String[] args) {
Student1 stu=new Student1();//Create object
Scanner input=new Scanner(System.in);
System.out.print("Please enter your name: ");
stu.setName(input.next());
System.out.print("Please enter your age: ");
stu.setAge(input.nextInt());
stu.print();//call
}
}
2. Write a class output property
package com.bdqn.demo;
import java.util.Scanner;
public class Student2 {
private String name;//姓名
private int age;//age
private String subject;//Occupation
private String sex;//gender
public Student2() {//No parameter construction
}
public Student2(String name,int age){//Specify properties
if(age>=0) {
this.age=age;}else {
System.out.println("The age is unreasonable to restore the default 18 years old!");
this.age=18;
}
this.name=name;
this.sex="男";
this.subject="java";
}
public Student2(String name,int age,String sex,String subject) {//指定属性
this.name=name;
if(age>=0) {//If the age is illogical, return the default value
this.age=age;}else {
System.out.println("The age is unreasonable to restore the default 18 years old!");
this.age=18;
}
this.sex=sex;
this.subject=subject;
}
public void print() {//Output printing
System.out.println("Hello everyone, my name is "+name+", age is "+age+", gender is "+sex+", professional skills are "+subject);
}
/**
*
* Test the use of the constructor
*/
public static void main(String[] args) {
Student2 stu = null;
Scanner input=new Scanner(System.in);
System.out.print("Please enter your name: ");
String name =input.next();
System.out.print("Please enter your age: ");
int age =input.nextInt();
stu = new Student2(name,age);
stu.print();//call
System.out.print("Please enter your name: ");
String name1 =input.next();
System.out.print("Please enter your age: ");
int age1 =input.nextInt();
System.out.print("Please enter your gender: ");
String sex =input.next();
System.out.print("Please enter your occupation: ");
String subject =input.next();
stu = new Student2(name1,age1,sex,subject);//Pass data
stu.print();//call
}
}
