Please tell me the output of following code and tell me the error in this code.

Question

import java.util.Scanner;

public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
String rev = "";
int len=text.length();

for(int i=len-1;i>=0;i--){
rev = rev+text.CharAt(i);
}
System.out.println(rev);

}
}

Answer 1

The loop should continue while <i> was greater than or equal to zero. That is ... `i >= 0` , not `i <= 0`

for( int i = len -1; i >= 0; i--)

A typo in writing method name, it's charAt() , not CharAt()

rev = rev + text.charAt( i );

Answer 2

Ya thanks but it is showing that cannot find symbol at <.CharAt>

Answer 3

Thanks it works

Answer 4

Because it should be `charAt` rather than `CharAt`

Notice the first letter 'c' and 'C'

Java is case sensitive language, a different letter case matters.

Answer 5

Iwas stucked only because of this 'c'

Answer 6

LOL it happens, take it easy ...
