java - 如何使用 lambdaj 或其他工具过滤表

Question

如何使用 lambdaj 过滤表格？

给出下表:

id  name   age  male  salary1   tom    22    y      3k2   nancy  24    n      3.5k3   jack   22    y      2k4   jmme   29    y      4k

If I applied the filter:

age >= 22 && salary > 3k

然后我会得到:

2   nancy  24    n      3.5k4   jmme   29    y      4k

As you know, I cannot create a domain class for it, which prevents me from using the following syntax:

filter(having(on(Person.class).getAge(),greaterThan(22)), myManList);
