JAVA基础 - 自定义异常类

自定义异常类，代码还不是很明白，先存着以后参考。

package week6;

class ScoreException extends Exception {
    
    private static final long serialVersionUID = 1L;

    public ScoreException() {
        super();
    }
    
    public ScoreException(String str) {
        super(str);
    }
    
}

class Student {
    
    private String name;
    private int score;
    
    public Student() {
        super();
    }
    
    public Student(String name, int score) throws ScoreException {
        super();
        this.name = name;
        if(score >= 0 && score <= 100) {
            this.score = score;
        }else {
            throw new ScoreException("Wrong Score");
        }
    }
    
    public String showName() {
        return this.name;
    }
    public int showScore() {
        return this.score;
    }
}

public class Week6 {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try {
            Student LiMing = new Student("Liming",-1);
        }catch(ScoreException e) {
            e.printStackTrace();
        }
    }

}
