Consider this Java code that checks multiple marks:

int mark1 = 5, mark2 = 4, mark3 = 3;
if (mark1 >= 4 && mark2 >= 4 && mark3 >= 4) {
    System.out.println("All marks are greater or equal than 4");
} else if (mark1 < 4 || mark2 < 4 || mark3 < 4) {
    System.out.println("Some marks are not greater or equal than 4");
} else {
    System.out.println("No mark is greater or equal than 4");
}
