    I have written a code which runs fine on my JAVA IDE, but saying ~no response~ in the output on the site. The code is given below:

    import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

    public static void main(String[] args) {
        /* Enter your code here. Read input from STDIN. Print output to STDOUT. Your class should be named Solution. */
        
        String the1Regex = "\\bpublic\\sclass\\b";
		String the2Regex = "\\bmain\\b";
        Scanner sc = new Scanner(System.in);
        String inputString = sc.next();
        
        Pattern checkRegex = Pattern.compile(the1Regex);
		Pattern checkRegex1 = Pattern.compile(the2Regex);
		Matcher regexMatcher = checkRegex.matcher(inputString);
		Matcher regexMatcher1 = checkRegex1.matcher(inputString);
			if(regexMatcher.find()){
			if(regexMatcher.group().length() != 0){
					System.out.println(inputString.substring(regexMatcher.end()+1, inputString.indexOf('{'))); 
			}
           }
			else 
				if(regexMatcher1.find()){
				if(regexMatcher1.group().length()!=0){
				System.out.println(inputString.substring(0,regexMatcher1.start()).substring(
						inputString.substring(0,regexMatcher1.start()).indexOf('c')+6, 
						inputString.substring(0,regexMatcher1.start()).indexOf('{')));
			}
           }
	   }
}
