[Solved] How to invert a word? [closed]

You can use StringBuffer or StringBuilder for this task, StringBuilder would be my choice since its more efficient. its not thread safe so multiple threads can call its methods simultaneously.

String reversedString = new StringBuilder(originalString).reverse().toString()

If you prefer not to use API support you can do something like this

static String reverse(String stringIn) {
    char[] cArr = stringIn.toCharArray();
    for (int i = 0; i < cArr.length/2; ++i){
        char c = cArr[i];
        cArr[i] = cArr[cArr.length-1-i];
        cArr[cArr.length-1-i] = c;
    }
    return new String(cArr);
}
