BorderLayout Sub-east, the default is the layout of the frame FlowLayout is the default layout for the panel GridLayout is a grid layout! You can specify the number of meshes when instantiating a grid layout object The panel must be added to a container to be displayed! An event is an object that describes what happened, and these objects are provided by AWT, such as left-click to produce a ActionEvent object The event source is a component of the event that occurs, such as clicki

Java training notes (8)-MYSQL Today, we will first explain the functions, which are mainly divided: 1. Aggregate functions 2. String Functions 3. Date Functions 4. mathematical functions Aggregate Function: A value is generated after a group of values are calculated. Common functions include: Function Name Function meaning Count () Count non-empty rows Max (), min () Ma
