How to make parameter in xpath and make codes easier to read if there are several same lines, java, selenium

I wrote this boolean method but I want to make it shorter and smarter since there are 3 same lines with quite the same XPath.
Could anyone help me with this, please? thanks

	public boolean VerifyKORSecDispaly() {
	
	boolean a = driver
			.findElement(By
					.xpath("(//tr[@data-testid='row']//td[@class='kor'])[1]//span[@class='da']"))
			.getText().contains("d");
	boolean b = driver
			.findElement(By
					.xpath("(//tr[@data-testid='row']//td[@class='kor'])[2]//span[@class='da']"))
			.getText().contains("d");
	boolean c = driver
			.findElement(By
					.xpath("(//tr[@data-testid='row']//td[@class='kor'])[3]//span[@class='da']"))
			.getText().contains("d");

	if (a == true && b == true && c == true) {
		return true;
	} else {
		return false;
	}
}

You could use List<> since you use indexes in xpath.

//tr[@data-testid='row']//td[@class='kor'] <- this selector would return multiple elements

Based on these elements, we can find span[@class='da'] element.

Code:

public boolean VerifyKORSecDispaly() {
    boolean a = doesRowTextContain(0, "d");
    boolean b = doesRowTextContain(1, "d");
    boolean c = doesRowTextContain(2, "d");

    if (a == true && b == true && c == true) {
        return true;
    } else {
        return false;
    }
}

private boolean doesRowTextContain(int index, String expectedString) {
	By spanSelector = By.xpath(".//span[@class='da']"); //the dot . reduces the scope of the element. Instead of searching through all the elements in source, we'll reduce the scope to parent element
	List<WebElement> dataRows = driver.findElements(By.xpath("//tr[@data-testid='row']//td[@class='kor']"));
	
	return dataRows.get(index).findElement(spanSelector).getText().contains(expectedString);
}

One more thing is - you don't have to compare a, b or c with true as it's default expected value in if statement.

    if (a && b && c) {
        return true;
    } else {
        return false;
    }

Or even

return a && b && c

Final methods could look like this:

public boolean VerifyKORSecDispaly() {
    return doesRowTextContain(0, "d") && doesRowTextContain(1, "d") && doesRowTextContain(2, "d");
}

private boolean doesRowTextContain(int index, String expectedString) {
	By spanSelector = By.xpath(".//span[@class='da']"); //the dot . reduces the scope of the element. Instead of searching through all the elements in source, we'll reduce the scope to parent element
	List<WebElement> dataRows = driver.findElements(By.xpath("//tr[@data-testid='row']//td[@class='kor']"));
	
	return dataRows.get(index).findElement(spanSelector).getText().contains(expectedString);
}
