Question

Write code to print the location of any alphabetic character in the 2-character string passcode.

Answer 1

Use the String class's indexOf() method to find the location of alphabetic characters in a string.

Step-by-step explanation:

To print the location of any alphabetic character in the 2-character string passcode, you can use the String class's indexOf() method. Here's an example:

String passcode = "ab";
for (int i = 0; i < passcode.length(); i++) {
if (Character.isAlphabetic(passcode.charAt(i))) {
int location = passcode.indexOf(passcode.charAt(i));
System.out.println("Location of " + passcode.charAt(i) + " is at index " + location);
}
}

In this code, we iterate through each character in the string passcode. If the character is alphabetic, we use the indexOf() method to find its location and print it.
