spring-boot-starter-web: spring-boot-starter:spring-boot场景启动器;帮我们导入了web模块正常运行所依赖的组件; Spring Boot将所有的功能场景都抽取出来,做成一个个的starters(启动器),只需要在项目里面引入这些starter ,相关场景的所有依赖都会导入进来。 要用什么功能就导入什么场景的启动器 。 2.3. 插件 插件在...
classArithmeticException 当出现异常的运算条件时,抛出此异常。 classArrayIndexOutOfBoundsException 用非法索引访问数组时抛出的异常。 classArrayStoreException 试图将错误类型的对象存储到一个对象数组时抛出的异常。 classClassCastException 当试图将对象强制转换为不是实例的子类时,抛出该异常。
Arithmetic expressions are composed of themselves, arithmetic operations, identifiers (whose value is treated as a numeric literal), and numeric literals. Conditional expressions are composed of themselves, comparison operations, and logical operations. ...
Note that in two's complement arithmetic, the three other basic arithmetic operations of add, subtract, and multiply are bit-wise identical if the two operands are regarded as both being signed or both being unsigned. Therefore separate addUnsigned, etc. methods are not provided. Parameters: div...
Requires the developer to catch any arithmetic exceptions that occur during block or expression evaluation. using System; short x = 32767; short y = 32767; checked { try { short z = y + z; } catch (OverflowException e) { //executed } } decimal Defines a 128 bit number. decimal d ...
A peculiarity of two's complement integer arithmetic is that the minimum negative value does not have a matching positive value of the same magnitude. So, , and, for integer , does not imply . The same edge case occurs for . As of Java SE 8, the class also contains methods for various...
quiet NaNs andsignaling NaNs. The differences between the two kinds of NaN are generally not visible in Java. Arithmetic operations on signaling NaNs turn them into quiet NaNs with a different, but often similar, bit pattern. However, on some processors merely copying a signaling NaN also pe...
