trycatch.java

java经典的源代码 我非常喜欢这个源代码 对于编程很有好处

//trycatch.java
public class trycatch {    
      // execute application
       public static void main( String args[] )
       {
          // call method1 
         try {
            method1();
         }   
         // catch Exceptions thrown from method1
         catch ( Exception exception ) {
            System.err.println( exception.getMessage() + "\n" );
            exception.printStackTrace();
         }
      }   
      // call method2; throw exceptions back to main
      public static void method1() throws Exception
      {
         method2();
      }   
      // call method3; throw exceptions back to method1
      public static void method2() throws Exception
      {
		method3();
	 }
	 public static void method3() throws Exception
	{
		throw new Exception("Exception thrown in method3");
	}
}
