Question

我有一个从webelement中提取的字符串数组。数组名称是＆＃39; ExtendedFeatures＆＃39;

我想将每个值组成一个字符串＆quot; fullfeatures1＆＃39;，用逗号分隔。

例如：val1，val1，val3 ......

这里我提取了值，最后循环遍历数组，试图追加字符串值。没有太大的成功。

    int size1 = all_ExtendedFeatures.size();
    for (WebElement ele : all_ExtendedFeatures)
        ExtendedFeatures.add(ele.getAttribute("innerHTML"));
    for (int i1 = 0; i1 < size1; i1++)
        System.out.println("Features - " + ExtendedFeatures.get(i1));

    for (int i1 = 0; i1 < size1; i1++) {

     // This is where i want to append values...
        String fullfeatures1 = str.concat(ExtendedFeatures.get(i1));

        System.out.println("Features -" +fullfeatures1);

    }

Answer 1

您可以使用以下String.join：

String commaSeparatedFeatures = String.join(",", ExtendedFeatures);

Answer 2

您可以在启动循环之前创建String变量 String str =“”; 然后你可以串起来像 str + = ExtendedFeatures.get（i1）;

Answer 3

要将值放在由逗号 (,)分隔的一个字符串 fullfeatures1 中，您可以使用以下代码块：

int size1 = all_ExtendedFeatures.size();
for (WebElement ele : all_ExtendedFeatures)
    ExtendedFeatures.add(ele.getAttribute("innerHTML"));
for (int i1 = 0; i1 < size1; i1++)
    System.out.println("Features - " + ExtendedFeatures.get(i1));
StringBuilder fullfeatures1 = new StringBuilder();
for ( int i = 0; i< size1; i++){
    fullfeatures1.append(ExtendedFeatures.get(i));
    if ( i != ExtendedFeatures.size()-1){
        fullfeatures1.append(", ");
    }
}
System.out.println(fullfeatures1.toString());

将String Array附加到单个字符串
