Question about java for lab class for compiler errors and editing a class

Notice that there are compiler errors in part5.Lab5. You will notice that the code in methods check_1, check_2, check_3, and check_4 makes calls to methods that should be defined in Vocabulary. This gives you a hint of something that you need to add to the Vocabulary class.

Keep in mind that you may edit ONLY the Vocabulary class, as that's the only class from part 5 that will be submitted. The Vocabulary class must make use of the part5.Words class.

----------The Lab5.java code is:-------------------------

package part5;

public class Lab5 {

private Vocabulary _vocab;

public Lab5() {
    _vocab = new Vocabulary();
    check_01();
    check_02();
    check_03();
    check_04();
    check_05();
    check_06();
    check_07();
    check_08();
    check_21();
    check_22();
    check_23();
    check_24();
}

public void check_01() {
    System.out.println("I expected to get:");
    System.out.println("    a");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1());
}

public void check_02() {
    System.out.println("I expected to get:");
    System.out.println("    some");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1());
}

public void check_03() {
    System.out.println("I expected to get:");
    System.out.println("    every");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1());
}

public void check_04() {
    System.out.println("I expected to get:");
    System.out.println("    a");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1());
    _vocab.get1();
    _vocab.get1();
}

public void check_05() {
    System.out.println("I expected to get:");
    System.out.println("    cat");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get2());
}

public void check_06() {
    System.out.println("I expected to get:");
    System.out.println("    dog");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get2());
}

public void check_07() {
    System.out.println("I expected to get:");
    System.out.println("    rat");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get2());
}

public void check_08() {
    System.out.println("I expected to get:");
    System.out.println("    cat");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get2());
    _vocab.get2();
    _vocab.get2();
}

// When submitting to Web-CAT additional test cases, 09 through 20, will be run.

public void check_21() {
    System.out.println("I expected to get:");
    System.out.println("    a cat chased some dog");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1() + " " + _vocab.get2() + " " + _vocab.get3() + " " + _vocab.get4() + " " + _vocab.get5());
}

public void check_22() {
    System.out.println("I expected to get:");
    System.out.println("    some dog scared every rat");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1() + " " + _vocab.get2() + " " + _vocab.get3() + " " + _vocab.get4() + " " + _vocab.get5());
}

public void check_23() {
    System.out.println("I expected to get:");
    System.out.println("    every rat convinced a cat");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1() + " " + _vocab.get2() + " " + _vocab.get3() + " " + _vocab.get4() + " " + _vocab.get5());
}

public void check_24() {
    System.out.println("I expected to get:");
    System.out.println("    a cat chased some dog");
    System.out.println("What I got was: ");
    System.out.println("    " + _vocab.get1() + " " + _vocab.get2() + " " + _vocab.get3() + " " + _vocab.get4() + " " + _vocab.get5());
}

}

-------The Vocalbulary.java is:-------------

package part5;

public class Vocabulary {

public Vocabulary() {
}

}

---------The Words.java is:---------------------

package part5;

public class Words { private String _word1; private String _word2; private String _word3;

public Words(String s1, String s2, String s3) {
    _word1 = s1;
    _word2 = s2;
    _word3 = s3;
}

public String getWord() {
    String answer = _word1;
    rotate();
    return answer;
}

private void rotate() {
    String temp = _word1;
    _word1 = _word2;
    _word2 = _word3;
    _word3 = temp;
}

}
