Java程序检查TPP学生参加面试的资格

背景

TPP（Technology Pioneer Program）是一个由Google组织的免费的技术学习和人才推荐计划，旨在培养和推荐具有优秀技术和思维能力的高校学生。每年的计划需要经过严格的筛选和面试，才能有机会参加。

在对学生的筛选过程中，我们需要一个Java程序来检查学生是否符合参加面试的资格，以确保计划的公正性和可行性。在这篇文章中，我将介绍如何编写这个Java程序。

需求

在编写Java程序进行校验之前，我们需要了解TPP对学生的要求。学生参加TPP面试需要满足以下要求：

-年龄在18-25岁之间

-本科或硕士在读学生

-计算机或相关专业学科相关专业

-有较强的英语听说读写能力

-熟练掌握至少一门编程语言

根据以上要求，我们可以开始编写Java程序进行筛选和校验。

程序实现

我们先定义一个学生类，用于存储学生的信息：

public class Student {
    private String name; //姓名
    private int age; //年龄
    private String major; //专业
    private boolean isUndergraduate; //是否为本科在读学生
    private boolean isGraduate; //是否为硕士在读学生
    private boolean canSpeakEnglish; //是否具有良好的英语口语表达能力
    private boolean canListenEnglish; //是否具有良好的英语听力能力
    private boolean canWriteEnglish; //是否具有良好的英语写作能力
    private boolean canReadEnglish; //是否具有良好的英语阅读能力
    private List<String> programmingLanguages; //已掌握编程语言列表

    //构造方法
    public Student(String name, int age, String major, boolean isUndergraduate, boolean isGraduate, boolean canSpeakEnglish, boolean canListenEnglish, boolean canWriteEnglish, boolean canReadEnglish, List<String> programmingLanguages) {
        this.name = name;
        this.age = age;
        this.major = major;
        this.isUndergraduate = isUndergraduate;
        this.isGraduate = isGraduate;
        this.canSpeakEnglish = canSpeakEnglish;
        this.canListenEnglish = canListenEnglish;
        this.canWriteEnglish = canWriteEnglish;
        this.canReadEnglish = canReadEnglish;
        this.programmingLanguages = programmingLanguages;
    }

    //getter 和 setter 方法

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public String getMajor() {
        return major;
    }

    public void setMajor(String major) {
        this.major = major;
    }

    public boolean isUndergraduate() {
        return isUndergraduate;
    }

    public void setUndergraduate(boolean undergraduate) {
        isUndergraduate = undergraduate;
    }

    public boolean isGraduate() {
        return isGraduate;
    }

    public void setGraduate(boolean graduate) {
        isGraduate = graduate;
    }

    public boolean isCanSpeakEnglish() {
        return canSpeakEnglish;
    }

    public void setCanSpeakEnglish(boolean canSpeakEnglish) {
        this.canSpeakEnglish = canSpeakEnglish;
    }

    public boolean isCanListenEnglish() {
        return canListenEnglish;
    }

    public void setCanListenEnglish(boolean canListenEnglish) {
        this.canListenEnglish = canListenEnglish;
    }

    public boolean isCanWriteEnglish() {
        return canWriteEnglish;
    }

    public void setCanWriteEnglish(boolean canWriteEnglish) {
        this.canWriteEnglish = canWriteEnglish;
    }

    public boolean isCanReadEnglish() {
        return canReadEnglish;
    }

    public void setCanReadEnglish(boolean canReadEnglish) {
        this.canReadEnglish = canReadEnglish;
    }

    public List<String> getProgrammingLanguages() {
        return programmingLanguages;
    }

    public void setProgrammingLanguages(List<String> programmingLanguages) {
        this.programmingLanguages = programmingLanguages;
    }
}

然后我们定义一个校验类，用于校验学生是否符合TPP的要求：

public class Validator {
    public boolean validate(Student student) {
        //校验年龄
        int age = student.getAge();
        if (age < 18 || age > 25) {
            return false;
        }

        //校验专业
        String major = student.getMajor();
        if (!major.contains("计算机") && !major.contains("软件工程")) {
            return false;
        }

        //校验学位
        boolean isUndergraduate = student.isUndergraduate();
        boolean isGraduate = student.isGraduate();
        if (!isUndergraduate && !isGraduate) {
            return false;
        }

        //校验英语能力
        boolean canSpeakEnglish = student.isCanSpeakEnglish();
        boolean canListenEnglish = student.isCanListenEnglish();
        boolean canWriteEnglish = student.isCanWriteEnglish();
        boolean canReadEnglish = student.isCanReadEnglish();
        if (!canSpeakEnglish || !canListenEnglish || !canWriteEnglish || !canReadEnglish) {
            return false;
        }

        //校验已掌握的编程语言
        List<String> programmingLanguages = student.getProgrammingLanguages();
        if (programmingLanguages == null || programmingLanguages.size() == 0) {
            return false;
        }

        return true;
    }
}

最后，我们可以编写一个测试类，用于测试我们的校验程序：

public class Tester {
    public static void main(String[] args) {
        Validator validator = new Validator();
        List<String> programmingLanguages1 = new ArrayList<String>();
        programmingLanguages1.add("Java");
        programmingLanguages1.add("Python");

        Student student1 = new Student("张三", 21, "计算机科学与技术", true, false, true, true, true, true, programmingLanguages1);

        boolean result1 = validator.validate(student1);
        System.out.println("学生1是否符合参加面试的资格：" + result1);

        List<String> programmingLanguages2 = new ArrayList<String>();
        programmingLanguages2.add("C++");

        Student student2 = new Student("李四", 26, "数学", false, true, false, false, false, false, programmingLanguages2);

        boolean result2 = validator.validate(student2);
        System.out.println("学生2是否符合参加面试的资格：" + result2);
    }
}
