title: change a phone number as a string into all numbers
body: <p><img src="https://i.stack.imgur.com/k1kL7.png" alt="enter image description here">Im writing a program in java that is suppose to receive a phone number as a string, (ex. 1800helpmee) from the user and print out its corresponding numbers. 1800 435 7633 should be the answer. this is the code i have so far. I've loaded the number into the array. I am having an issue with the next part. my array is called inputNumber. I tried something like this but it doesn't seem to be working </p>
  
  <pre><code>for (int j = 0;  j&lt;9; j ++) { 
          if ( inputNumber[j] =='A' || inputNumber[j] == 'B' || inputNumber[j] =='C'){
              System.out.println("2");
          }  etc.
  </code></pre>
