今天的代码是关于跟踪异常传播:
下面是代码部分:
package lianxi;
import javax.swing.*;
public class bo {
public static void main(String[] args) {
try
{
method1();
}
catch ( Exception e )
{
System.err.println( e.getMessage() + "
" );
e.printStackTrace();
}
}
public static void method1() throws Exception
{
method2();
}
public static void method2() throws Exception
{
method3();
}
public static void method3() throws Exception
{
throw new Exception( "Exception thrown in method3" );
}
}
运行结果:
