I'm very much beginner to Java. I want to make a list containing strings and integers. Using If statement, want to delete an element in the list which is greater than 30 and print the new list. Can anybody please correct my code. public class IfStatement{ public class Delete{ public static void main (String [] args){ String Names={"Shraddha","Manjunath"}; int ages={23,35}; if (ages>30){ del ages; } } System.out.println(Names); } }
