After following, you can keep track of his dynamic information in a timely manner
wait(), notify() and notifyAll() are methods used for inter-thread communication in Java. They are defined in the Object class and must be called in a synchronization context. 2.wait() causes the current thread to release the lock and wait until other threads call notify() or notifyAll(); notify() wakes up a waiting thread; notifyAll() wakes up all waiting threads, and they will compete for the lock. 3. These methods avoid busy waiting and improve thread collaboration efficiency. 4. The example shows the producer-consumer model: the producer waits when the buffer is not empty and notifies the consumer after writing data; the consumer waits when there is no data in the buffer and notifies the producer after reading. 5.

Use CSS to customize the scroll bar style to improve the visual consistency of the web page. Modern browsers support different methods: WebKit core browsers (Chrome, Edge, Safari) set the width, background and slider through ::-webkit-scrollbar and its sub-elements; Firefox uses the scrollbar-width and scrollbar-color attributes to define the thickness and color. Styles can be applied globally or to specific elements (such as .custom-scroll). Pay attention to cross-browser compatibility and provide fallback solutions.

HTML5's range input type creates a slider control for selecting a range of values. Use type="range" to define the minimum value (min), maximum value (max), initial value (value) and step size (step). By default, the value is not displayed. JavaScript needs to be used to update the span or output element in real time to display the current value. Styles can be customized through CSS pseudo-elements such as ::-webkit-slider-thumb and ::-moz-range-thumb. Works like other inputs in the form, sending the selected value on submission. It is suitable for scenarios that do not require high-precision settings, scoring, etc. It natively supports modern browsers without additional

GROUPINGSETS allows multiple grouping combinations to be defined in a single query to efficiently implement custom aggregation. Through GROUPINGSETS, you can specify groups such as (Region, Year), (Region) and () to generate corresponding summary rows to avoid multiple queries or redundant UNIONALL. NULL in the result indicates the roll-up level, and the GROUPING() function can be used to distinguish actual NULL from aggregate placeholders. Compared with ROLLUP and CUBE, GROUPINGSETS is more flexible and accurate, generating only the required groups, improving performance and readability.

The answer is: To analyze Oracle table performance, you need to first check statistical information, execution plans, index usage and table data characteristics. First, confirm whether the table statistics are up-to-date. If they are missing or expired, use DBMS_STATS to collect them; then check the execution plan through EXPLAINPLAN to identify full table scans or high-cost operations; then check whether the index exists and is being used effectively, and rebuild or create new indexes if necessary; finally, evaluate the table size, row migration, and partitioning strategy to ensure that the data structure is reasonable. Regular maintenance can prevent performance degradation.
