Java Collections Java Index of an element of a java.util.Set can be found by converting it to an a java.util.List: package com.logicbig.example;import java.util.ArrayList;import java.util.HashSet;import java.util.Set;public class SetIndexExample { public static void main(String[] args...
why not? iterate over all elements, maintain a counter. when you meet your desired element you return the value of the counter. The time complexity is linear in size of the treeset. but I'm guessing this is not what you're looking for. Everything is possible — Barrack Schwarzenegger, ...
To find the index of an element in an int array in Java, you can use the indexOf() method of the Arrays class. The indexOf() method returns the index of the first occurrence of the specified element in the array, or -1 if the element is not found. Here is an example of how ...
WebElement element1 = driver.findElement(By.name("text-field")); WebElement element2 = element1.findElement(By.cssSelector(".")); AssertJUnit.assertEquals(element1, element2); WebElement element3 = element1.findElement(By.cssSelector(".:enabled")); AssertJUnit.assertEquals(element1, element3...
