怎样实现这个异常的循环？求大神

package ch06;

import java.util.InputMismatchException;
import java.util.Scanner;

public class DivideDemo {

/**
 * @param args
 */
public static void main(String[] args) {
    // TODO Auto-generated method stub
    try{
    Scanner sc=new Scanner(System.in);
    System.out.println("请输入被除数：");
    int a=sc.nextInt();
    System.out.println("请输入除数：");
    int b=sc.nextInt();
    int c=a/b;
    System.out.println("两者之商是："+c);
    System.out.println("我在学习异常！");

    }catch(InputMismatchException e){
        System.out.println("请输入整数！");
    }catch(ArithmeticException e){
        System.out.println("除数不可以为0！");
    }catch(Exception e){
        System.out.println("其他异常！");
    }finally{
        System.out.println("我学会异常了！");
    }
    System.out.println("我不再finally里面！");


}

}

 Boolean b = false;
do {
try{
    Scanner sc=new Scanner(System.in);
    System.out.println("请输入被除数：");
    int a=sc.nextInt();
    System.out.println("请输入除数：");
    int b=sc.nextInt();
    int c=a/b;
    System.out.println("两者之商是："+c);
    System.out.println("我在学习异常！");
    b = true;
    }catch(InputMismatchException e){
        System.out.println("请输入整数！");
    }catch(ArithmeticException e){
        System.out.println("除数不可以为0！");
    }catch(Exception e){
        System.out.println("其他异常！");
    }finally{
        System.out.println("我学会异常了！");
    }
    System.out.println("我不再finally里面！");
} while (!b);
