如,例 2-7 无法通过编译,并显示出错信息:local variables referenced from a Lambda expression must be final or effectively final1 。 例2-7未使用既成事实上的 final 变量,导致无法通过编译 String name = getUserName(); name = formatUserName(name); button.addActionListener(event -> System.out.printl...
否则是会报错的,但是jdk1.8放松了这个限制,可以使用非final修饰,但是这个变量,是不允许另外赋值的,否则lamdba体重也会报错,如图: 换句话说,Lambda 表达式引用的是值,而不是变量.所以在lamdba和匿名内部类中使用变量不能被改变 如果你试图给该变量多次赋值,然后在 Lambda 表达式中引用它,编译器就会报错,典型的就是在...

The dollar sign should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems. The underscore may be used in identifiers formed of two or more characters, but it cannot be used as a one-character identifier due to being a keyword (3.9...

you cannot use private methods outside the class, the final method can be used. you cannot override both private and final methods. you can hide the private method but the final method cannot be hidden, depending upon whether it is static or not. ...
This article is devoted to the study of a nonlinear Schrödinger equation with an x-periodic and t-quasi-periodic quintic nonlinear term. It is proved that the equation admits small-amplitude, linearly stable, real analytic, and quasi-periodic solution
