Solution in JAVA (judge verdict: Runtime Error)

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Main {
	public static void main(String[] args) throws IOException {
		BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

		String str = br.readLine();
		str = str+str;
		String keyword = br.readLine();
		boolean result = false;

		for(int i =0; i < str.length();i++){
			int index  = str.indexOf(keyword.charAt(0),i);
			if(index == -1)
				break;
			index++;
