java如何在方法上使用控制语句？如果可能的话

Question

我不知道该怎么说

如果是钱&书信电报；1000和房子（）；你是穷人吗

或者

如果是钱>=1000和<；5000和房子（）；是==正常打印你的ok，你的太丰富了

使用两者的返回值进行比较

private static String money() {

    System.out.println("please enter a number");
    int wage = scanner.nextInt();
    if (wage < 1000) {
        return "poor";
    } else if (wage >= 1000 && wage < 5000) {
        return "ok";
    } else if (wage > 5000) {
        return "rich";
    } else {
        //ask for input again or exit, whatever
    }
}

对house()执行同样的操作。然后，用另一种方法比较两者的返回值
