以下实例演示了使用多个 catch 来处理链试异常:
Main.java 文件
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); } } }}
以上代码运行输出结果为:
发算术异常: java.lang.ArithmeticException: / by zero手动抛出链试异常 : java.lang.NumberFormatException
