Reverse string method

Question

I am trying to solve the following problem but how do write the method that accepts String as an argument?

Write a method named printReverse

Answer 1

I highly recommend you to go through a basic tutorial.

You can simply do:

private static String myReverse(String str) {
    String reverse = "";
    int length = str.length();
    for( int i = length - 1 ; i >= 0 ; i-- ) {
       reverse = reverse + str.charAt(i);
    }
    return reverse;
}

And in your main, you simply:

String reversed = myReverse(in.nextLine());

Note that the method is static because you're referring to it from a static manner (main method). If you don't want it to be static, you'll have to access it via an object.

Also note that it's a good practice to always have curly brackets for for loops, even if it contains a single line.
