javaSE之运行时异常和编译时异常

Posted 2022-03-04 shijinglu2018

运行时异常继承自RuntimeException;

package foundationEnhance;


public class Person 
    private int age;

    public Person(int age) 
        super();
        if(age<0)
            throw new ageException("年龄不可以为负数！");
        
        this.age = age;
    

    public int getAge() 
        return age;
    

    public void setAge(int age) 
        if(age<0)
            throw new ageException("年龄不可以为负数！");
        
        this.age = age;
    

 

package foundationEnhance;

public class testPerson 
    public static void main(String[] args) 
        Person p=new Person(-1);
        p.setAge(-2);
        System.out.println(p.getAge());
    

 

package foundationEnhance;

public class ageException extends RuntimeException
    public ageException() 

    

    public ageException(String message) 
        super(message);
    

 

 

编译时异常继承自Exception;
