package five; public class five { public static void main(String[] args) { try { int a=args.length; System.out.println("\na = "+a); a=22; int b=42/a; int c[]= {1}; c[42]=99; } catch (ArithmeticException e) { System.out.println("发生了被0除: "+e); } catch (ArrayIndexOutOfBoundsException e) { System.out.println("数组下标越界: "+e); } finally { System.out.println("finally 语句被执行");} } }请用vector类改写一下

可以使用Vector类来代替数组：

import java.util.Vector;

public class Five {
    public static void main(String[] args) {
        try {
            int a = args.length;
            System.out.println("\na = " + a);
            a = 22;
            int b = 42 / a;
            Vector<Integer> c = new Vector<Integer>(1);
            c.set(42, 99);
        } catch (ArithmeticException e) {
            System.out.println("发生了被0除: " + e);
        } catch (ArrayIndexOutOfBoundsException e) {
            System.out.println("数组下标越界:  " + e);
        } finally {
            System.out.println("finally 语句被执行");
        }
    }
}

注意，这里使用了Vector类的set方法来设置元素值，因为Vector类没有像数组那样有预先定义的大小。
