  1. If syntax errors fixed in arr and arrList declarations, compilation error arises due to not reachable “s” in code block of if statement

    public static void main(String[] args) {
    String[] arr = {“Hi”, “How”, “Are”, “You”};
    List arrList = new ArrayList(Arrays.asList(arr));

    if(arrList.removeIf(s -> { return s.length() <= 2;})){
    System.out.println(s+ " removed");

  2. A:
    Test17.java:3: error: ‘)’ expected
    String [] arr = (“Hi”, “How”, “Are”, “You”);
    Test17.java:5: error: ‘;’ expected
    if (arrList.removeIf((string s) -> (return s.length() <=2 ))) {
    Test17.java:9: error: class, interface, or enum expected
    14 errors
