java如何在catch块中增加值？

Question

我是编程新手。这是我的设想。我正在测试一个站点。如果某个链接未建立，则应转到捕捉块并移动到下一步。如果在k循环中失败，它应该执行k++；不是i++；或j++。如果在j循环中失败，则应增加j值，而不是i值或k值。怎么做

public static void main(String[] args) throws NoSuchElementException {
    int i = 0, j = 0, k = 0;
    String links[] = new String[10];
    links[0] = "link1";
    links[1] = "link2";
    links[2] = "link3";
    links[3] = "link4";
    WebDriver driver = new FirefoxDriver();

    while (i < 4) {
        try {
            driver.get(links[i]);
            driver.findElement(By.xpath("//div[contains(@id,'image')]")).click();
            while (j < 5) {
                driver.findElement(By.xpath("//div[contains(@id,'header')]")).click();
                while (k < 8) {
                    driver.findElement(By.xpath("//div[contains(@id,'title')]")).click();
                    k++;
                }
                j++;
            }
            i++;
        } catch (NoSuchElementException e) {
            System.out.println(e);
            // How to increment the  value of i or j or k
        }
    }
}

在代码的顶部，有：

char currentLoop = 'i';

然后在每次while循环声明之后立即相应地设置值，如下所示：

while (i < 4) {
    currentLoop = 'i';
    ...

    while (j < 5) {
        currentLoop = 'j';
        ...

        while (k < 8) {
            currentLoop = 'k';
            ...
        }
    }
}

然后在捕获过程中：

if (currentLoop == 'i') {
    i++;
}else if (currentLoop == 'j') {
    j++;
}else if (currentLoop == 'k') {
    k++;
}
