Тестовое задание на java
я его уже завалил =) теперь интересно почему.
Implement SimpleArrayList and write unit tests for the class.
Implement ReverseList.reverseList (List list) method and write unit tests for the class.
SimpleArrayList
package questions; import java.util.Iterator; /** * SimpleList implements some methods of List interface * * * */ public class SimpleArrayList { //array to store elements of the list Object[] data; /** * Specified by: the same method of java.util.List * @param index * @return */ public Object get(int index){ //todo: implement } /** * Specified by: the same method of java.util.List * @param index * @param obj */ public Object set(int index, Object obj){ //todo: implement } /** * Specified by: the same method of java.util.List * @param index * @param element */ public void add(int index, Object element){ //todo: implement } /** * Specified by: the same method of java.util.List * @return */ public Iterator iterator(){ return new Iterator(){ //todo: implement }; } /** * Specified by: the same method of java.util.List * @return */ public int hashCode(){ //todo: implement } /** * Specified by: the same method of java.util.List * @return */ public boolean equals(Object obj) { //todo: impelment } /** * Specified by: the same method of java.util.List * @return */ public int indexOf(Object o){ ////todo: impelment } }ReverseList
package questions; import java.util.List; /** * Test task */ public class ReverseList { /** * reverse the list given as the param * !!! don't change the signature of the method * @param list to be reversed */ public static void reverseList(List list) { //todo: impelment } }
