這個(gè)題目很有意思。不用這么復(fù)雜。大概10幾句就做完了。

以前我用C#做過的。先把邏輯簡(jiǎn)化了。幾個(gè)IF THEN就搞定
public?static?void?main(String[]?args)?{
System.out.println("輸入你的收入：");
Scanner?input?=?new?Scanner(System.in);
double?money?=?input.nextFloat();
double?tax?=?0;
if(money?=?500){
tax?=?money?*?0.05;
}else?if(money??500??money?=?20000){
tax?=?money?*?0.1;
}
//?.....
System.out.println("納稅："?+?tax?+?"?元");
}
