lambda expression Lambda表达式是java Stream的使用基础。 lambda表达式的语法由参数列表、->和函数体组成。函数体既可以是一个表达式,也可以是一个语句块。表达式执行后会返回执行结果。语句块中使用return将控制权转给调用者。表达式函数体省略return,适用于小型表达式,使得语法更加简洁。 参数可以无参或多个参数,参数...
表达式(expression)是可以作为函数参数的,如:10*a; 语句(statement):不能作为函数参数,如:print(a)。 new test();是一条语句(statement)。i+1是一个表达式(expression),就像cron表达式、EL表达式、lambda表达式一样,不是statement。
You cannot use a lambda expression for the test expression in aSelect Casestatement. Lambda expression definitions return functions, and the test expression of aSelect Casestatement must be an elementary data type. The following code causes this error:...
