How to calculate the date one week later in Java 8
This example will calculate the date one week later. The LocalDate date does not contain time information. Its plus() method is used to add days, weeks, and months. The ChronoUnit class declares these time units. Since LocalDate is also an immutable type, you must use variables to assign values ??after returning.
package?com.shxt.demo02;??
import?java.time.LocalDate;??
import?java.time.temporal.ChronoUnit;??
public?class?Demo08?{??????
public?static?void?main(String[]?args)?{??????????
LocalDate?today?=?LocalDate.now();??????????
System.out.println("今天的日期為:"+today);??????????
LocalDate?nextWeek?=?today.plus(1,?ChronoUnit.WEEKS);??????????
System.out.println("一周后的日期為:"+nextWeek);??????
}??
}
You can see that the new date is 7 days from today’s date, which is one week. You can add 1 month, 1 year, 1 hour, 1 minute or even a century in the same way. For more options, check out the ChronoUnit class in the Java 8 API

How to handle transactions in Java with JDBC?
Aug 02, 2025 pm 12:29 PM
To correctly handle JDBC transactions, you must first turn off the automatic commit mode, then perform multiple operations, and finally commit or rollback according to the results; 1. Call conn.setAutoCommit(false) to start the transaction; 2. Execute multiple SQL operations, such as INSERT and UPDATE; 3. Call conn.commit() if all operations are successful, and call conn.rollback() if an exception occurs to ensure data consistency; at the same time, try-with-resources should be used to manage resources, properly handle exceptions and close connections to avoid connection leakage; in addition, it is recommended to use connection pools and set save points to achieve partial rollback, and keep transactions as short as possible to improve performance.

How to work with Calendar in Java?

Create a specific date and time using the of() method; 4. Use the plus/minus method to immutably increase and decrease the time; 5. Use ZonedDateTime and ZoneId to process the time zone; 6. Format and parse date strings through DateTimeFormatter; 7. Use Instant to be compatible with the old date types when necessary; date processing in modern Java should give priority to using java.timeAPI, which provides clear, immutable and linear
