假设我有以下代码:
public int getNumOfPostInstancesByTitle(String postMainTitle) {
int numOfIns = 0;
List<WebElement> blogTitlesList = driver.findElements(blogTitleLocator);
for (WebElement thisBlogTitle : blogTitlesList) {
String currentTitle = thisBlogTitle.getText();
if (currentTitle.equalsIgnoreCase(postMainTitle)) {
numOfIns++;
}
}
return numOfIns;
}
用谓词lambda转换的正确方法是什么?
最佳答案
您可以使用numOfInts
,map
和filter
的简单组合来计算count
:
return driver.findElements(blogTitleLocator)
.stream()
.map(WebElement::getText) // convert to a Stream of String
.filter(s -> s.equalsIgnoreCase(postMainTitle)) // accept only Strings
//equal to postMainTitle
.count(); // count the elements of the Stream that passed the filter
