We can use for loop to populate the new array without the element we want to remove. package com.journaldev.java; import java.util.Arrays; public class Main { public static void main(String[] args) { int[] arr = new int[]{1,2,3,4,5}; int[] arr_new = new int[arr.length-1]...

Remove Element Given an array and a value, remove all instances of that value in place and return the new length. The order of elements can be changed. It doesn't matter what you leave beyond the new length. 双指针法 复杂度 时间O(N) 空间 O(1) ...
Original Array : [25, 14, 56, 15, 36, 56, 77, 18, 29, 49] After removing the second element: [25, 56, 15, 36, 56, 77, 18, 29, 49, 49] Flowchart: For more Practice: Solve these Related Problems: Write a Java program to remove all occurrences of a given value from an ar...
Java list remove element（Java集合删除元素）简介 下面介绍Java中几种从list中删除元素的方法，根据不同情况应用不同的方法。还要注意List的生成方式，也会对删除元素有影响！方法/步骤 1 首先要看你的List是怎么生成的，比如：List<String> strList = Arrays.asList("a", "b", "aa", "ab", "ba");这种...

System.arraycopy(elementData, index+1, elementData, index, numMoved); elementData[--size] = null; // clear to let GC do its work } 我们在删除某个元素后,list的大小发生了变化,这时候你的的索引也会发生变化,这时就会导致你在遍历的时候漏掉某些元素。
