Scanner类的应用

package File;
import java.util.Scanner;

public class ScannerDemo {
public static void main(String[] args){
Scanner con=new Scanner(System.in);
String line=con.nextLine();
int i=con.nextInt();
double d=con.nextDouble();
System.out.println(line);
System.out.println(i);
System.out.println(d);
con.close();
}
}

对象序列化

package File;
import java.io.Serializable;
public class Person implements Serializable{
private String name;
private int age;
public String getName(){
return name;
}
public void setName(String name){
this.name=name;
}
public int getAge(){
return age;
}
public void setAge(int age){
this.age=age;
}
public String toString(){
return "姓名："+name+"，年龄："+age;
}
}
