定义一个类继承Exception定义一个Triangle类，输入三个边的长度，并判断是否满足三角形原理，
如果不满足则抛出一个自定义的异常。编程实现之。
package test;
import java.util.Scanner;
public class Triangle {
public static void main(String[] args) throws MyException {
Scanner s = new Scanner(System.in);
int a = s.nextInt();
int b = s.nextInt();
int c = s.nextInt();
if (a + b < c || a + c < b || c + b < a) {
throw new MyException("三边长度不能构成三角形");
}
s.close();
}
}
class MyException extends Exception {
/**
*
*/
private static final long serialVersionUID = 1L;
public MyException() {
// TODO Auto-generated constructor stub
super();
}
public MyException(String message) {
super(message);
}
}
import java.util.Scanner;
public class Triangle {
public static void main(String[] args) throws MyException {
Scanner s = new Scanner(System.in);
int a = s.nextInt();
int b = s.nextInt();
int c = s.nextInt();
if (a + b < c || a + c < b || c + b < a) {
throw new MyException("三边长度不能构成三角形");
}
s.close();
}
}
class MyException extends Exception {
/**
*
*/
private static final long serialVersionUID = 1L;
public MyException() {
// TODO Auto-generated constructor stub
super();
}
public MyException(String message) {
super(message);
}
}
