java如何通過鍵盤輸入性別代號(hào)

//用Scanner讀入字符串,加個(gè)判斷就可以了

public?static?void?main(String[]?args)?{

Scanner?s=new?Scanner(System.in);

String?sex=s.next();

if(sex.toLowerCase().equals("m"))

System.out.println("男性");

else?if(sex.toLowerCase().equals("n"))

System.out.println("女性");

else

System.out.println("未知");

}

java程序設(shè)計(jì)，用scanner編寫，輸入姓名，性別，年齡，住址，婚否，可以輸出相應(yīng)的數(shù)據(jù)？

package?test;

import?java.util.Scanner;??//?Import?the?Scanner?class

public?class?Test{

public?static?void?main(String[]?args)?{

Scanner?myObj?=?new?Scanner(System.in);??//?Create?a?Scanner?object

System.out.print("輸入年齡：");

String?age=?myObj.nextLine();??//?Read?user?input

System.out.print("輸入姓名：");

String?name=?myObj.nextLine();??//?Read?user?input

//再寫?地點(diǎn)。。。

System.out.println(name+"?你好，今年"?+?age+"歲");??//?Output?user?input

}}

用JAVA編寫一個(gè)程序，要求如下：

實(shí)現(xiàn)代碼如下：

Student類：

public class Student {

private String name;

private String sex;

private int age;

private double chinese;

private double math;

private double english;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getSex() {

return sex;

}

public void setSex(String sex) {

this.sex = sex;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public double getChinese() {

return chinese;

}

public void setChinese(double chinese) {

this.chinese = chinese;

}

public double getMath() {

return math;

}

public void setMath(double math) {

this.math = math;

}

public double getEnglish() {

return english;

}

public void setEnglish(double english) {

this.english = english;

}

}

-----------------------------------------------------------------

StudentTest類：（測(cè)試類）

import java.util.Scanner;

public class StudentTest {

public static void main(String[] args) {

Student student = new Student();

Scanner sc = new Scanner(System.in);

System.out.println("請(qǐng)輸入姓名：");

student.setName(sc.next());

System.out.println("請(qǐng)輸入性別：");

student.setSex(sc.next());

System.out.println("請(qǐng)輸入年齡：");

student.setAge(sc.nextInt());

System.out.println("請(qǐng)輸入語文成績(jī)、數(shù)學(xué)成績(jī)、英語成績(jī)：");

student.setChinese(sc.nextDouble());

student.setMath(sc.nextDouble());

student.setEnglish(sc.nextDouble());

Double count = student.getChinese()+ student.getMath()+student.getEnglish();

System.out.println("姓名："+student.getName()+" 性別："+student.getSex()+" 年齡："+student.getAge());

System.out.println("總分："+count+" 平均分："+count/3);

}

}
