How do I click on an element that appears sometimes 1 or sometimes 2 at different intervals - selenium

Question

I have done this
List<WebElement> element= driver.findElements(By.xpath(""));
for(int i=0;element.size();i++)
{
driver.findElements(By.xpath("")).isDisplayed();
driver.findElements(By.xpath("")).click();
}
I am new to java and selenium , so I thought of doing this. Is this logic correct or am I wrong? If wrong(most probably) , can you please rectify and explain alongside , wud be very helpful.
I get element not interactable error on this.

In case you are looking for method to wait for one of two elements to appear and then to click on the appeared element you can use this method:
public String waitForOneOfTwoElements(String xpath1, String xpath2){
wait = new WebDriverWait(driver, 30);
try {
wait.until(ExpectedConditions.or(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath1)),
ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath2))));
if(waitForElementToBeVisible(xpath1)){
return xpath1;
}else if(waitForElementToBeVisible(xpath2)){
return xpath2;
}
}catch (Throwable t){
return null;
}
}
Where waitForElementToBeVisible is:
public boolean waitForElementToBeVisible(String xpath) {
wait = new WebDriverWait(driver, 30);
try {
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath(xpath)));
return true;
}catch (Throwable t) {
return false;
}
}
Now, when you get the appeared element you can simply click it with:
String appearedElementXpath = waitForOneOfTwoElements(xpath1,xpath2);
driver.findElement(By.xpath(appearedElementXpath)).click();
