Java에서 예외가 생성되는 방법

package prac;
public class t2 {
	public static void main(String[] args) throws Exception {
		// TODO Auto-generated method stub
		m1();
	}

	public static void m1() throws Exception {
		System.out.println("m1----------start");
		m2();
		// 手动抛出受查异常
		throw new Exception();
		//System.out.println("m1----------end");
	}

	public static void m2() {
		System.out.println("m2----------start");
		// 手动抛出运行时异常，需要携带信息“程序因为异常而终止”
		throw new RuntimeException("程序因为异常而终止");
		//System.out.println("m2----------end");
	}
}
程序运行结果为：
m1----------start
m2----------start
Exception in thread "main" java.lang.RuntimeException: 程序因为异常而终止
