因此，我正在Eclipse中使用JUnit测试用例，我的构造函数出现错误，显示“默认构造函数无法处理由隐式超构造函数引发的异常类型InvalidArgException。必须定义显式构造函数”。
我会把我目前掌握的一切都包括在内，但是我被困在这里，不知道现在该怎么办。任何帮助都将不胜感激！！
这是测试类

package test;

    import static org.junit.jupiter.api.Assertions.*;

    import org.junit.jupiter.api.Test;

    import Main.Contact;

    class ContactTest {

Contact contact = new Contact("13579", "Garrett", "Strang", "1234567890", "2468 Washington Avenue");

@Test
void getContactID() {
    assertEquals("13579", contact.getContactID());
}

@Test
void getFirstname() {
    assertEquals("Garrett", contact.getFirstName());
}

@Test
void getLastName() {
    assertEquals("Strang", contact.getLastName());
}

@Test
void getPhoneNumber() {
    assertEquals("1234567890", contact.getPhoneNumber());
}

@Test
void getAddress() {
    assertEquals("2468 Washington Avenue", contact.getAddress());
}

}
联系人类：

public class Contact {

//declare private contact objects
private String contactID;
private String firstName;
private String lastName;
private String phoneNum;
private String address;

//Ensure invalid objects are caught  

public Contact(String cID, String fN, String lN, String pN, String addr) throws InvalidArgException {

    //contact ID string cannot be longer than 10 characters. The contact ID shall not be null and shall not be updatable.
    if (cID == null || cID.length() > 10) {
        throw new InvalidArgException("CONTACT ID IS INVALID");
    }
    if (fN == null || fN.length() > 10) {
        throw new InvalidArgException("FIRST NAME IS INVALID");
    }
    if (lN == null || lN.length() > 10) {
        throw new InvalidArgException("LAST NAME IS INVALID");
    }
    if (pN == null || pN.length() > 10) {
        throw new InvalidArgException("PHONE NUMBER IS INVALID");
    }
    if (addr == null || addr.length() > 10) {
        throw new InvalidArgException("ADDRESS IS INVALID");
    }   

}

InvalidArgExcetion类别：

package Main;

    @SuppressWarnings("serial")
    public class InvalidArgException extends Exception {

public InvalidArgException(String string) {
    super(string);
    System.out.println(string + "IS AN INVALID ARGUMENT");
}

}
