How do I use if statements to get a base^0 to = 1?

I am attempting to write a program that calculates exponents using loops and if statement and arrays,I am very new to java. I am using an if statement in my loop to say if exp == 0 answer = 1, then store that into an array, but it always comes out as 0 no matter what. How do I fix this?

int[] expList = new int[numExponents]; 

  for(int i = 0; i < expList.length; i++)
  {
      System.out.print("Enter the base: ");
      int base = in.nextInt();

      System.out.print("Enter the exponent: ");
      int exp = in.nextInt();

      int answer = 1;
      for(int number = 0; number < exp; number++)             
      {
          if (exp == 0)
          {
              answer = 1;
              expList[number] = answer;
          }
          if (exp >= 1)
          {
              answer *= base;
              expList[number] = answer;
          } 
      }
  }
  System.out.println(Arrays.toString(expList))          

Note that numExponents is the number of exponents the user wants to calculate.
