清单大小 <webelement> 迭代后增加

Question

I have a problem with my code, the size of my list increases after for iteration :

@FindBy(xpath = "//b[@ng-click='column.visible=!column.visible;']")
List<WebElement> columnsNotChecked;
int i = 0 ;
    this.waitElementToBeClickable(columns);
    columns.click();
    System.out.println("Value : " + columnsNotChecked.size());
    for (WebElement webElement : columnsNotChecked) {
        if (i!=7) {
            webElement.click();
        }
        System.out.println(i);
        i++;
    }
    System.out.println("Value : " + columnsNotChecked.size());

This is the output : Value : 13, 0 1 2 3 4 5 6 7 8 9 10 11 12, Value : 21

can somebody help me please ?

try this code :

List<WebElement> columnsNotChecked = driver.findElements(By.xpath("//b[@ng-click='column.visible=!column.visible;']"));  
System.out.println("This is the size of list:"+columnsNotChecked.size());  
this.waitElementToBeClickable(columns);
columns.click();  
int i =0 ;

for(WebElement webElement :columnsNotChecked){
if(i!=7){
webElement.click();
}
System.out.println(i);
        i++;
}

 System.out.println("Value : " + columnsNotChecked.size());
