Here is the English translation of your request:

**Define a variable `strDate` which can represent any date (in the format: yyyy-mm-dd). Now, we need to write code to calculate the date that is 35 full working days after `strDate` (excluding weekends). Please provide high-quality and comprehensive code. Thank you.**

### Supplementary Information:

It definitely means moving forward. Replace "35" with Chinese characters: "三十五天" (35 days).

### Additional Clarification:

**Approach:**
1. Add 35 days to the given date.
```java
Date date = new Date();
date.setDate(date.getDate() + 35);
```
2. Subtract the weekends within this period.
```java
// SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
Date curr = new Date();
Date backDate = new Date();
backDate.setDate(backDate.getDate() + 35); // The date 35 days later.
int day = (int) ((backDate.getTime() - curr.getTime()) / (1000 * 3600 * 24));
int count = 0; // Count the number of weekends.
int week = curr.getDay(); // Day of the week.
for (int i = 0; i < day; i++) {
System.out.println("i:" + week);
if (week == 6) { // Saturday
count++;
week = 0;
} else if (week == 0) { // Sunday
count++;
week++;
} else {
week++;
}
}
date.setDate(date.getDate() - count);
```
Is there anything overlooked in this approach...?

### Solutions Provided:
1. **Clarification Needed:**
Is the 35-day difference forward or backward? And by excluding weekends, does it mean no weekends should be included in these 35 days?
2. **ORA-01000 Issue:**
For problems related to exceeding the maximum number of open cursors, adding or subtracting date-type variables in Java can lead to `java.lang.VirtualMachineError`. This can be resolved accordingly.
3. **Proposed Solution:**
Follow the same logic as described earlier but ensure proper handling of edge cases. For example:
```java
import java.util.Date;
import java.text.SimpleDateFormat;
public class Main {
public static void main(String[] args) {
try {
// Define the starting date (strDate)
String strDate = "2023-10-01"; // Example date
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date startDate = sdf.parse(strDate);
// Calculate 35 working days later
Date resultDate = addWorkingDays(startDate, 35);
System.out.println("Result Date: " + sdf.format(resultDate));
} catch (Exception e) {
e.printStackTrace();
}
}
public static Date addWorkingDays(Date startDate, int workingDays) {
long millisecondsInDay = 1000L * 60 * 60 * 24;
int addedDays = 0;
Date currentDate = new Date(startDate.getTime());
while (addedDays < workingDays) {
currentDate.setTime(currentDate.getTime() + millisecondsInDay);
int dayOfWeek = currentDate.getDay();
if (dayOfWeek != 0 && dayOfWeek != 6) { // Exclude Sunday (0) and Saturday (6)
addedDays++;
}
}
return currentDate;
}
}
```

This solution ensures clarity, handles edge cases (like weekends), and provides a robust implementation. Let me know if further clarification is needed!
