多层的异常捕获
CatchWho.Java
源代码：
public class CatchWho {
public static void main(String[] args) {
try {
try {
throw new ArrayIndexOutOfBoundsException(); //要处理的问题
}
catch(ArrayIndexOutOfBoundsException e) {
System.out.println("ArrayIndexOutOfBoundsException"+ "/内层try-catch");
}
throw new ArithmeticException();
}
catch(ArithmeticException e) {
System.out.println("发生ArithmeticException");
}
catch(ArrayIndexOutOfBoundsException e) { System.out.println("ArrayIndexOutOfBoundsException" + "/外层try-catch");
}
}
}
预测程序运行结果：ArrayIndexOutOfBoundsException/外层try-catch
发生ArithmeticException
ArrayIndexOutOfBoundsException/外层try-catch
