Question

You are developing a system to process lists of days of the week, represented as strings. Create a function is_weekend that consumes a list and returns whether the list has the string "Saturday" or the string "Sunday" in it. Call and print this function once with a list of days of the week.

Answer 1

public static boolean is_weekend(List week){

if(week.contains("Saturday")||week.contains("Sunday"))

{

System.out.println("List has a weekend");

return true;

}

else{

System.out.println("List has no weekend");

return false;

}

}

Step-by-step explanation:

• Using java programming language
• Import java.util.ArrayList and import java.util.List; so you can implement a java list
• Create a list and add the days of the week
• Create the required method using the contains() method to check for Sunday and Saturday and return true if the list contains them
• See the complete program with a call to the method

import java.util.ArrayList;

import java.util.List;

public class Car {

public static void main(String[] args) {

List<String> daysOfWeek = new ArrayList<>();

daysOfWeek.add("Sunday");

daysOfWeek.add("Moday");

daysOfWeek.add("Tuesday");

daysOfWeek.add("Wednesday");

daysOfWeek.add("Thursday");

daysOfWeek.add("Friday");

daysOfWeek.add("Saturday");

is_weekend(daysOfWeek);

}

public static boolean is_weekend(List week){

if(week.contains("Saturday")||week.contains("Sunday"))

{

System.out.println("List has a weekend");

return true;

}

else{

System.out.println("List has no weekend");

return false;

}

}

}
