i am not sure whats wrong with the if condition and logical operator

problem with if statement and logical operator

package time;
import java.util.*;


public class Changetime {
        
        @SuppressWarnings("resource")
        public static void main (String[] args)
        {
                Scanner scan = new Scanner(System.in);
                boolean r = true;
                while (r==true)
                { 
                        System.out.println("Enter time as h:m:s AM/PM");
                
int h=scan.nextInt();
int m=scan.nextInt();
int s=scan.nextInt();
String t=scan.nextLine();

System.out.println("time entered is => "+(String.format("%02d",h)) +":" +(String.format("%02d",m))+":"+(String.format("%02d",s)) +t );

if (h<12 && t.equalsIgnoreCase("pm"))
{
        h=h+12;
        System.out.println("\n your 24 hr format time is  " +(String.format("%02d",h)) +":" +(String.format("%02d",m))+":"+(String.format("%02d",s))+" hrs");
}
if (h==12 && t.equalsIgnoreCase("am"))
{h=h-12;
System.out.println("\n your 24 hr format time is  " +(String.format("%02d",h)) +":" +(String.format("%02d",m))+":"+(String.format("%02d",s))+" hrs");
}

}
 
        }
}

its a program to change time into 24 hr format, its not checking statements at if condition its compiling but during run time its not processing the conditions ...tell me whats wrong.
