在这个示例中,原数组array包含了5个元素,我们通过创建一个长度为4的新数组newArray,将array中的前4个元素复制到newArray中,然后将newArray赋值给array,实现了删除最后一个元素的效果。 方法二:使用ArrayList 另一种方法是使用Java提供的ArrayList类。ArrayList是一个动态数组,它实现了List接口,可以根据需要动态调整大小。
for (int i = 0; i 1.2、直接使用list.remove(Object o)ArrayList.remove(Object o)源码的逻辑和ArrayList.remove(int index)大致相同:列表索引坐标从小到大循环遍历,若列表中存在与入参对象相等的元素,则把该元素移除,后面的元素都往左移动一位,返回true,若不存在与入参相等的元素,返回false。 ```java publi...

Do not allocate extra space for another array, you must do this bymodifying the input array in-placewith O(1) extra memory. The order of elements can be changed. It doesn't matter what you leave beyond the new length. 示例1:
mergeArray, mergeBooleanArray, mergeByteArray, mergeCharArray, mergeDoubleArray, mergeFloatArray, mergeIntArray, mergeLongArray, mod, mod, octalValue, out, out, out, out, out, pad, parseBandwidth, parseBandwidth, parseDelimitedString, parseHex, parseHex, parseMemorySize, parseMemorySize...
