如何将未检查的从整数转换为T?我在此行收到此警告:
undoStackIndexes.push((T)index);
编码:
SimpleStack<T> undoStackIndexes = new SimpleStack<T>();
SimpleStack<T> undoStackDatas = new SimpleStack<T>();
public void add( int idx, T x ){
Node<T> p = getNode( idx, 0, size( ) );
Node<T> newNode = new Node<T>( x, p.prev, p );
newNode.prev.next = newNode;
p.prev = newNode;
theSize++;
modCount++;
undoStackDatas.push(newNode.data);
Integer index = new Integer(idx);
undoStackIndexes.push((T)index);
}
最佳答案
如果您知道要在Integer
堆栈中存储undoStackIndexes
索引,则不应使它与T
类型通用:
SimpleStack<Integer> undoStackIndexes = new SimpleStack<Integer>();
