我无法修复“线程中的异常”主“java.lang.ArithmeticException：/ by zero”

Question

这是我的计划。我发现它没有任何问题，但是当我试图运行它时会出现一个错误，即我将其除以零。

import acm.program.*;  
public class ReverseDigits extends Program {  
public void run(){
println("This program reverses the digits in an integer."); 
int n = readInt("Enter a positive integer: ");
int x = 10;  
int t = 1;
int total = 0;
 //Finds the number of digits
 while (n > 0){
    while (n % x != 0) {
        t = t + 1;
        x = x * 10;
}
}
//In case the number has one digit the new number is the same
if(t == 1) {
 total = n;
}
//Creating the new number
while (t > 1) {
      t=t-1;
      total = (total + ((( n / (10^t)) - ((n /  (10 ^ (t+1))) * 10 )) * 10));
     } 
  println("The reverse number is " + total); 
   }  
}

尝试运行时遇到此错误，但我找不到问题。

Exception in thread "main" java.lang.ArithmeticException: / by zero

Answer 1

^ - 是一个XOR操作，而不是程度！您需要Math.pow(number, degree);
