[Solved] Programmr “replacing and converting Strings” Java [closed]

by


Okay, now that you’ve explained your problem and where it is you’re stuck, I am much more able to help you.

What you’re trying to do is compare a char to an array. You can’t do. You need to loop over the array for each character, as such:

char[] splitNumber = encryptedNumber.toCharArray();

for (int i=0; i < encryptedNumber.length(); i++) {
    char c = encryptedNumber.charAt(i);
    for (int j=0; j < conversionTable.length; j++) {
        if (c == conversionTable[j][0].charAt(0)) {
            // do whatever you want here
        }
    }
}

The inner loop will iterate over the rows of the array and for each row j, will retrieve the value in its’ first column (at index 0).
