If you prefer not to use an array and keep it simple with just Strings, then: String myWord = "abc"; String reversed = ""; for (int i = myWord.length() - 1; i >= 0; i--) reversed += myWord.charAt(i); System.out.println(reversed);

public class Program { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String text = scanner.nextLine(); char[] arr = text.toCharArray(); String reversed = ""; for(int i = arr.length - 1; i >= 0; i--) { reversed += arr[i]; } System.out.println(reversed); } } Use the for loop starting from the last item in the array and work backwards. Array items start at 0 so when using the length variable the last item in the array will be 1 less. e.g. An array length of 4 { 0 , 1 , 2 , 3 } Final item index is 3. Concatenate the character array items into a string using the operand +. The example above: reversed += arr[i]; Is the same as: reversed = reversed + arr[i]; Then print the string to console. You should store the result in a variable this can make it easy to call back to if you need to use it somewhere else. Hope this helps.

Instead of using "println", in this case works better coding just "print". That way everything goes in the same line. So: import java.util.Scanner; public class Program { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); String text = scanner.nextLine(); char[] arr = text.toCharArray(); //tu código va aquí for(int i=arr.length-1;i>=0;i--) { System.out.print(arr[i]); } } }
