如何写一个返回一个对象和一个整数的方法？

public Map<String, Object> getObjectAndInt() {
    // 方法体
}

public Map<String, Object> getObjectAndInt() {
    Map<String, Object> result = new HashMap<>();
    result.put("object", yourObject);
    result.put("integer", yourInteger);
    return result;
}

Map<String, Object> resultMap = getObjectAndInt();
YourObject object = (YourObject) resultMap.get("object");
int integerValue = (int) resultMap.get("integer");
