ArithmeticException與混合分數計算器

Question

此程序正確計算混合分數。我希望while循環在我輸入兩個零時終止。然而，當我輸入兩個零分隔的空間時，我得到「異常在線程」主要「java.lang.ArithmeticException：/由零在MixedFractions.main等我只是想讓用戶無法輸入值和是一旦他們兩個變量輸入0謝謝

import java.util.Scanner; 
public class MixedFractions { 
public static void main (String [] args) 
{ 

    Scanner scan = new Scanner(System.in); 
    int a = scan.nextInt(); int b = scan.nextInt(); 
    int c = Math.abs(a/b); 
    int d = c * b; 
    int e = c * b; 
    int f = a - e; 
    while (a != 0 && b!= 0) 
    { 


     if(c == 0) 
     { 
      System.out.println(c + " " + a + "/" + b); 
     } 
     else if(d == a) 
     { 
      a = 0; 
      System.out.println(c + " " + a + "/" + b); 

     } 
     else if(c != a) 
     { 
      e = c * b; 
      f = a - e; 
      System.out.println(c + " " + f + "/" + b); 
     } 
     a = scan.nextInt(); b = scan.nextInt(); 
     c = Math.abs(a/b); 
    } 
} 

}

試試這個：

public static void main (String [] args) { 

    Scanner scan = new Scanner(System.in); 
    int a = scan.nextInt(); 
    int b = scan.nextInt(); 
    while (a != 0 && b!= 0) { 
     int c = Math.abs(a/b); 
     int d = c * b; 
     if(c == 0) { 
      System.out.println(c + " " + a + "/" + b); 
     } else if(d == a) { 
      a = 0; 
      System.out.println(c + " " + a + "/" + b); 
     } else if(c != a) { 
      int e = c * b; 
      int f = a - e; 
      System.out.println(c + " " + f + "/" + b); 
     } 
     a = scan.nextInt(); 
     b = scan.nextInt(); 
    } 
}
