Returns an array containing all of the elements in this list in proper sequence (from first to last element). The returned array will be “safe” in that no references to it are maintained by this list. (In other words, this method must allocate a new array even if this list is backed...
Note that toArray(new Object[0]) is identical in function to toArray().Overrides:toArray in interface Collection Params:a – the array into which the elements of this list are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this ...

java中的toArray 1.1 集合接口1.1.1 集合的接口与实现分离与现代的数据结构类库的常见情况一样,java集合类库也将接口(interface)与实现(implemention)分离。以队列为例进行讲解,队列接口指出可以再队列的尾部添加元素,在队列的头部删除元素,并且可以查找队列中元素的个数。一个队列的最小形式可能类似于下面这样:interfac...

Java.util.concurrent.LinkedTransferQueue的toArray()方法是Java的内置函数,用于生成与LinkedTransferQueue相同元素的数组。本质上,它将所有元素从LinkedTransferQueue复制到新数组。 用法: public Object[]toArray() 参数:此方法不接受任何参数。 返回值:此方法返回一个包含此队列的所有元素的数组,作为其数组表示形式。
Java Set的toArray()方法用于生成与Set元素相同的元素的数组。本质上,它将所有元素从Set复制到新数组。 用法: Object[]toArray() 参数:该方法不带任何参数。 返回值:该方法返回一个数组,其中包含与Set类似的元素。 以下示例程序旨在说明Set.toArray()方法: ...
