insertElementAt()方法 在java.util包中的Vector类中使用,用于将特定元素插入到向量的指定索引处。元素和位置都作为参数传递。如果在指定的索引处插入元素,则所有元素都向上推移一个位置,因此容量增加,为新元素创建空间。 语法: Vector.insertElementAt() Java Copy 参数: 该方法接受两个参数: element: 需要插入到向量...

Java example to insert an element at the end of the LinkedList collection. Submitted byNidhi, on April 13, 2022 Problem statement In this program, we will create a Linked List for country names using a Linked List collection. Then we will add an item at the end using theaddLast() method...
In themain()function, we created an arrayIntArraythat contains 6 integer items. Then we read an item from the user. Then we find the array element, which is greater than the input item. After that, we performed a shift operation to insert an item at the correct location, and then we...
(If the index is equal to the current size of the vector, the new element is appended to the Vector.) This method is identical in functionality to the #add(int, Object) add(int, E) method (which is part of the List interface). Note that the add method reverses the order of the ...
