public class TimeConversion { public static void main(String[] args) { String s="07:05:45PM"; System.out.println(timeConversion(s)); }

static String timeConversion(String s) {
    /*
     * Write your code here.
     */
    String str="";
    if(!s.substring(0,2).equals("12")&&s.contains("PM")){
        str= Integer.toString(Integer.parseInt(s.substring(0,2))+12);
        s =str+s.substring(2,s.length());
    }
    if(s.substring(0,2).equals("12")&&s.contains("AM")){
        str="00";
        s =str+s.substring(2,s.length());
    }
            Test cases are falingin for this solution , can anyone provide me the solution an

    return s.substring(0,s.length()-2);
}
