Java習題3：簡單定義一個團隊類

問題描述：定義一個類:團隊(Team)，該類中包含一些其它類的物件（教師，研究生，本科生等），為該類定義一個有參的構造方法及一些方法來描述團隊的行為，

代碼實作如下：

Team類（團隊，團隊中包括教師，研究生，本科生）：

package experiment2;

public class Team {
	private String name;//團隊名稱
	private int max;//團隊人數
	private String pName;//專案名稱
	private Teacher teacher;//指導老師
	private GraduateStudent[] gStudents;//研究生陣列
	private UnderGStudent[] uGStudents; //本科生陣列
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Teacher getTeacher() {
		return teacher;
	}
	public void setMax(int max) {
		this.max = max;
	}
	public int getMax() {
		return max;
	}
	public String getpName() {
		return pName;
	}
	public void setpName(String pName) {
		this.pName = pName;
	}
	public void setTeacher(Teacher teacher) {
		this.teacher = teacher;
	}
	public GraduateStudent[] getgStudents() {
		return gStudents;
	}
	public void setgStudents(GraduateStudent[] gStudents) {
		this.gStudents = gStudents;
	}
	public UnderGStudent[] getuGStudents() {
		return uGStudents;
	}
	public void setuGStudenst(UnderGStudent[] uGStudents) {
		this.uGStudents = uGStudents;
	}
	public Team(String name,int max,String pName) {
		this.setpName(pName);
		this.setName(name);
		this.setMax(max);
		gStudents = new GraduateStudent[max/2]; 
		uGStudents = new UnderGStudent[max-max/2];
	}
	//指導老師加入團隊
	public void tInTeam(Teacher tTeacher){
		teacher = tTeacher;
        System.out.println("指導老師" + teacher.getName() + "成功加入" + getName()+"團隊" );
    }
	//研究生加入團隊
	public void gSInTeam(GraduateStudent gStudent){
    	for(int i=0;i<gStudents.length;i++) {
    		if(gStudents[i]==null) {
    			gStudents[i]=gStudent;
                System.out.println("研究生" + gStudent.getName() + "成功加入" + getName()+"團隊" );
                break;
    		}
    		if(i==gStudents.length-1) {
    			System.out.println( "研究生" + gStudent.getName() + "加入失敗," +getName()+"團隊研究生組已滿員");
    		}
    	}
    }
	//本科生加入團隊
	public void uGSInTeam(UnderGStudent uGStudent) {
    	for(int i=0;i<uGStudents.length;i++) {
    		if(uGStudents[i]==null) {
    			uGStudents[i]=uGStudent;
                System.out.println("本科生" + uGStudent.getName() + "成功加入" + getName()+"團隊" );
                break;
    		}
    		if(i==uGStudents.length-1) {
    			System.out.println( "本科生" + uGStudent.getName()+"加入失敗," + getName()+"團隊本科生組已滿員");
    		}
    	}
	}
	//輸出團隊資訊
	public void outputInfo() {
		System.out.println("團隊名稱:" + getName() + " 指導老師:" + getTeacher().getName() + " 專案名稱:" + getpName());
		System.out.println("研究生成員:");
		for(int i = 0;i < gStudents.length;i++){
		    if(gStudents[i] != null)
		    System.out.printf(gStudents[i].getName()+" ");
		}
		System.out.println();
		System.out.println("本科生成員:");
		for(int i = 0;i < uGStudents.length;i++)
		{
		    if(uGStudents[i] != null)
		        System.out.printf(uGStudents[i].getName()+" ");
		}
		System.out.println();
	}
	//指導老師指導專案
	public void guideProject() {
		System.out.println("指導老師" + getTeacher().getName() + "正在指導" + getpName()+ "團隊專案，");
	}
}

Teacher類（指導老師）：

package experiment2;

public class Teacher {
	private String name;
	private String sex;
	private int age;
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;

		this.setAge(age);
		this.setEduBack(eduBack);
	}
}

UnderGStudent類（本科生）：

package experiment2;

public class UnderGStudent {
	private String name;
	private String sex;
	private int age;
	private String eduBack;
	public String getName() {

}

TeamTest類（測驗類）：

package experiment2;

public class TeamTest {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Teacher teacher = new Teacher("楊斌","男",30);
		GraduateStudent gStudent1 = new GraduateStudent("李超","男",23,"研究生");
		GraduateStudent gStudent2 = new GraduateStudent("劉麗","女",22,"研究生");
