扫描仪类:
import java.util.Scanner;
Scanner input=new Scanner(System.in);
示例:
import java.util.Scanner;
public class Test02 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入名字:");
String name = input.next();
System.out.println("请输入年龄:");
int age = input.nextInt();
System.out.println("请输入性别:");
char gehder = input.next().charAt(0);
}
}
获得4位数各位
int custNo = input.nextInt();
int gewei = custNo % 10;
int shiwei = custNo / 10 % 10;
int baiwei = custNo / 100 % 10;
int qianwei = custNo / 1000;
