java - IntelliJ - 无法解析符号 'Arrays'

Question

1. 我的代码

SDK 级别

SDK

我正在使用

1. Windows 7 32 位操作系统
2. Java 版本“1.8.0_221”
3. IntelliJ Idea 11.0.2

我正在用 Java 编写一个基本程序。但我收到编译错误:

Cannot resolve the symbol 'Arrays'

我的代码是这样的:

import java.util.Arrays;
import java.util.Collections;

import java.util.List;

public class EmployeesData {

    public static List<Employee> getEmployees() {
        return Arrays.asList(
                new Employee(201, "Kumar", "MS", 20000),
                new Employee(202, "Kiran", "Wells", 30000),
                new Employee(201, "Kumar", "Wells", 40000), 
                new Employee(203, "Vishal", "MS", 25000),
                new Employee(203, "Srikanth", "MS", 45000),
                new Employee(204, "Vimal", "Wells", 50000));
    }

    public static List<Employee> getEmployees2() {
        String a = null;
        return Collections.singletonList(
                new Employee(201, "Kumar", "MS", 20000),
                new Employee(202, "Kiran", "Wells", 30000),
                new Employee(201, "Kumar", "Wells", 40000),
                new Employee(203, "Vishal", "MS", 25000),
                new Employee(203, "Srikanth", "MS", 45000),
                new Employee(204, "Vimal", "Wells", 50000));
    }
}

对于 Collections 类，我也遇到了同样的错误。

我也在 E​​clipse 中尝试过，我在 Eclipse 中也面临同样的问题。我也尝试指定库。甚至没有解决。可能我必须在设置中做额外的事情。

以下作品...

public static List<Employee> getEmployees() {

        Employee[] e = {new Employee(201, "Kumar", "MS", 20000),
                new Employee(202, "Kiran", "Wells", 30000),
                new Employee(201, "Kumar", "Wells", 40000), 
                new Employee(203, "Vishal", "MS", 25000),
                new Employee(203, "Srikanth", "MS", 45000),
                new Employee(204, "Vimal", "Wells", 50000)};

        return Arrays.asList(e);
    }

...我怀疑编译器不喜欢 new 关键字。
