我也是刚学，你可以看看
package cn.tndu.wuliao;
import java.util.Scanner;
public class Employee {
private static String name;
private static Stringcard;
private static double salary;
private static double bonus;

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.println("请输入您的姓名");
name = scanner.next();
System.out.println("请输入您的身份证号");
card= scanner.next();
System.out.println("请输入您的基本工资");
String next1 = scanner.next();
System.out.println("请输入您的奖金");
String next2 = scanner.next();

if (next1!=null && next2!=null) {
salary=Double.parseDouble(next1);
bonus=Double.parseDouble(next2);
double tax = getTax();
System.out.println(name+"的所得税是:"+tax);

}
}
public static double getTax() {
return (salary+bonus-800)*0.2;
}
}
