@asdf2014 I think we already have a pretty thorough outstanding PR for spelling errors here. #275 Perhaps it would be cleaner if you contribute additional spelling errors that you have found there instead of spreading them out over multiple pull requests.

@afine Thank you for code review. Due to...

public void equalsNullPointException() throws Exception {
    String normal = "", unmoral = null;
    try {
        if (normal.equals("") && unmoral.equals("")) {     // bad habit
    } catch (Exception e) {
        System.out.println("Will throw NullPointException!");
        assertEquals(true, e instanceof NullPointerException);
    boolean equals = false;
    if ("".equals(normal) || "".equals(unmoral)) {         // good habit
        equals = true;
    assertEquals(true, equals);

Full code is here.
