问题
判断当前容器中是否全部包含指定容器中的所有元素,若包含,返回true,否则,返回false
解决:
public boolean containsAll(Collection<?> c) {
if (c instanceof Bag) {
Bag other = (Bag) c;
Object[] thisElemets = this.elements;
Object[] otherElements = other.elements;
for (int i = 0; i < other.counter; i++) {
Object temp= otherElements[i];
if(!this.contains(temp)) {
return false;
}
}
}
return true;
}
