Cannot invoke "String.equalsIgnoreCase(String)" because "text" is null

I apologize for the inconvenience. It seems like you are trying to invoke the `equalsIgnoreCase` method on a null value. Please ensure that the `text` variable is not null before calling the method. You can use a null check condition to handle such cases. For example:

if (text != null && text.equalsIgnoreCase("desiredText")) {
    // Perform desired actions
}

This way, you can avoid invoking methods on null values and prevent potential NullPointerExceptions.

Cannot invoke "String.equalsIgnoreCase(String)" because "code" is null

I apologize for the inconvenience. It seems that the variable "code" is currently null, which is causing the error when trying to invoke the `equalsIgnoreCase()` method on it.

To avoid this error, you should check if the "code" variable is null before invoking any methods on it. You can use an if statement or a null check to ensure that the variable has a value before performing any operations on it.

Here's an example of how you can modify your code to handle this situation:

if (code != null && code.equalsIgnoreCase("yourString")) {
    // Perform the desired operation
}

By checking if the "code" variable is null before invoking the `equalsIgnoreCase()` method, you can prevent the error from occurring.

Cannot invoke String.equals(Object) because pro1 is null

这个错误是因为你调用了一个空对象的 equals 方法。你需要先检查 pro1 是否为 null，然后再调用 equals 方法。例如：

if (pro1 != null && pro1.equals("someString")) {
    // do something
}

这样就可以避免因为空对象引起的 NullPointerException 错误。
