1. UsingArraysClass To check if an element is in an array, we can useArraysclass to convert the array toArrayListand use thecontains()method to check the item’s presence. We can use theindexOf()method to find the index of item in the array. In the case of an array of custom obje...
private static void check(int[] arr, int toCheckValue) { boolean test = false; for (int element : arr) { if (element == toCheckValue) { test = true; break; } } System.out.println("Is " + toCheckValue + " present in the array: " + test); } public static void main(String[...
In this article, we will see different ways to check if array contains element in PowerShell using -contains operator, Contains() method, Where-Object cmdlet,

modCount; } public E set(int index, E element) { rangeCheck(index); checkForComodification(); // 直接调用 AbstractList 对象的 set(int, E) 方法, // 通过加上偏移量来保证正确性 return l.set(index+offset, element); } public E get(int index) { // 检查 index 下标是否越界,如果是,...
