Logic for

Create a method ABC that takes two integer parameters, one for minutes and one for seconds, and prints the grade based on the following

15 Presentation is longer than 5 minutes and no longer than 7 minutes

10 Presentation is between 4 minutes 30 Seconds and 5 minutes OR between 7 minutes and 7 minutes and 30 seconds

Call from a main program.

What I have tried:

Java

public class ABC {

    public static String gradeTiming(int minute, int second) {
        String display;
        if (minute >=5 and <= 7); {
            display = "15";
        } 
        
        return String.format("%02d:%02d %s", minute, second, display);
    }

Read carefully the requirements (for instance, ABC should be the name of the method, not of the class).
In order to implement the method logic, it is useful to convert minutes and seconds to, total seconds and use it.
Try

Java

public class MyGrader
{ 
  public static void ABC( int minutes, int seconds )
  {
    String grade = "unknown";
    int total_seconds = minutes * 60 + seconds;
    if ( (total_seconds >= 270 && total_seconds < 300) || (total_seconds >= 420 && total_seconds < 450))
      grade = "10";
    else if (total_seconds >= 300 && total_seconds < 420)
      grade = "15";
    System.out.println(grade);

  }

  public static void main( String args[])
  {
    ABC(4,35);
  }
}

Look here: Java Operators[^] - it covers the java logical operators &&, ||, and ! which provide what you need.
The word and in your code is wrong - you want to use the AND operator && instead, and the syntax is also incorrect:

Java

if (a >= 0 && a <= 10) {
   System.out.println("a is in range");
   }

Will give you a display provided a is between 0 and 10 inclusive.
Think about the question, and you'll get the idea!
