Java example - chain test exception

The following example demonstrates the use of multiple catches to handle chain test exceptions:

/*

 Main.java
 */public class Main{
   public static void main (String args[])throws Exception  {
      int n=20,result=0;
      try{
         result=n/0;
         System.out.println("结果为"+result);
      }
      catch(ArithmeticException ex){
         System.out.println("发算术异常: "+ex);
         try {
         throw new NumberFormatException();
         }
         catch(NumberFormatException ex1) {
            System.out.println("手动抛出链试异常 : "+ex1);
         }
      }
   }
   }

##The above code The running output result is:

发算术异常: java.lang.ArithmeticException: / by zero
手动抛出链试异常 : java.lang.NumberFormatException
