Problem Statement: Your task is to remove all spaces or dashes from a string credit CardNumber. For example, if credit CardNumber is "4123-5678-9812-3450", then you should set it to "4123567890123450". Credit Card Information (all fields are required) We Accept Credit Card Type: Credit Card Number Step 1 Decide what work must be done inside the loop. In the loop, we visit each character in turn. You can get the ith character as char ch credit CardNumber.charAt(1); If it is not a dash or space, we move on to the next character. If it is a dash or space, we remove the offending character i=0 While Set ch to the ith character of credit CardNumber. If ch is a space or dash Remove the character from credit CardNumber. Else (Do not enter spaces or deshes) Increment i. You may wonder how to remove a character from a string in Java. Here is the procedure for removing the character at position 1: Take the substrings that end before i and start after 1, and concatenate them. before after
