    Default Code is not giving the desired output

    So im a begineer in java and im trying to write a code to tell me how many days there are in a specific month but febuary is giving 29 no matter if the year is a leap year or not and i cant seem to find the reason I would really apreciate some help as i have been staring and revising this for at least an hour to no avail.Thanks to anyone who helps.


    import java.util.Scanner;
    import static java.lang.System.out;
    import static java.lang.System.in;
    public class Calander {
     
    	public static void main(String[] args) {
     
    		Scanner sc = new Scanner(in);
    		int year;
    		int leapyear;
    		int month;
    		boolean leapyearTF = false;
     
    		out.print("Enter the year: ");
    			year = sc.nextInt();
     
    		out.print("Enter the month: ");	
    			month = sc.nextInt();
     
    		leapyear = year % 4;
     
    		if(leapyear == 0){
    			leapyearTF = true;
    			}else
    				leapyearTF = false;
    			leapyearTF = false;
     
    		switch(month){
     
    		case 1:
    		case 3:
    		case 5:
    		case 7:
    		case 8:
    		case 10:
    		case 12:	
     
    			out.println("There are 31 days in this month");
    				break;
     
    		case 4:
    		case 6:
    		case 9:
    		case 11:
     
    			out.println("There are 30 days in this month");
     
    		case 2:
    			if(leapyearTF = true){
     
    				out.print("There are 29 days in this month");
    			}else 
    				out.print("There are 28 days in this month");
     
    				break;
    	 }
     
      }
     
    }

    Can you post the contents of the console window that shows what was entered into the program and what the program printed out when the program was executed?
    Add some comments to the output explaining what is wrong with it.

    if(leapyearTF = true){
    There is a problem here. = is the assignment operator and == is the equality testing operator.
    There is no need to compare a boolean variable to true or false. This will work:
    if(leapyearTF){
    The if() statement requires an expression that has a boolean value. A boolean variable has that.
    If you don't understand my answer, don't ignore it, ask a question.

    Okay,

    Enter the year: 1998
    Enter the month: 2
    There are 29 days in this month


    I would like the output to read 28 days rather than 29 beacause 1998 is not a leap year. The reason its wrong is 1998 % 4 is 2 not 0 so leapyearTF should be false ,but it still prints 29 days.
