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程序设计,用scanner编写,输入姓名,性别,年龄,住址,婚否,可以输出相应的数据?
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("输入年龄:");
String age= myObj.nextLine(); // Read user input
System.out.print("输入姓名:");
String name= myObj.nextLine(); // Read user input
//再写 地点。。。
System.out.println(name+" 你好,今年" + age+"岁"); // Output user input
}}
用JAVA编写一个程序,要求如下:
实现代码如下:
Student类:
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类:(测试类)
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("请输入姓名:");
student.setName(sc.next());
System.out.println("请输入性别:");
student.setSex(sc.next());
System.out.println("请输入年龄:");
student.setAge(sc.nextInt());
System.out.println("请输入语文成绩、数学成绩、英语成绩:");
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()+" 性别:"+student.getSex()+" 年龄:"+student.getAge());
System.out.println("总分:"+count+" 平均分:"+count/3);
}
}
运行结果为:
分享标题:请输入性别的Java代码 运行查询时提示请输入性别
