It will cause problems when traversing the array, because the deletion or insertion of elements will change the index structure, while the loop variables or iterators are not updated synchronously, resulting in skipping elements or exceptions; for example, when traversing from front to back in JavaScript and deleting elements, subsequent elements move forward but incrementing indexes will skip the next element; directly modifying the list in Python may raise a RuntimeError or behavioral exception; methods to avoid this problem include: 1. Reverse traversal, deleting elements does not affect unprocessed low-index items; 2. Collect the index or elements to be modified first, and then process them uniformly after iteration, and the deletion requires reverse order operation; 3. Use functional methods such as filter and map to generate a new array to avoid mutation of the original array; also pay attention to forE

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.
