Answer 1

1st way

class ReverseString
{
public static void main(String args[])
{
String s=args[0];
StringBuffer sb=new StringBuffer(s);
System.out.println(“The reverse of “ + s + “ is “ + sb.reverse());

}
}

In the above program String and StringBuffer both of them are classes

Since String will not contain reverse method we are passing String parameter to StringBuffer and calling reverse method available in StringBuffer

Way 2:

class ReverseString
{
public static void main(String args[])
{
String s=args[0];
System.out.println(“The reverse of “ + s + “ is “);
for(int i=(s.length()-1);i>=0;i--)
System.out.print(s.charAt(i));
}
}

In this method we are calculating length of a string
Later on assigning strong length -1 to a variable named i
Finally printing characters one by one using getChar method

Answer 2

You can use string builder or buffer for it

Or iterate through entire loop backwards

{
public static void main(String args[])
{
Scanner scan = new Scanner(System.in);
String s=scan.nextLine();
StringBuffer sb=new StringBuffer(s);
sb.reverse();
System.out.println("\"" + s + "\" isminin tersten yazılışı : \n" + sb );
}
}
