键字怎么写

计算机

键字的写法主要取决于所使用的语言或计算机程序的语法规则。一般情况下，关键字需要按照规定的写法进行书写，例如在 Java 语言中，关键字需要全部小写，而在 Python 语言中，则需要全部大写。以下是一些常见编程语言中的关键字写法：

Java：ABStract, boolean, break, byte, case, catch, char, class, const, continue, default, do, double, else, extends, final, finally, float, for, goto, if, implements, import, instanceof, int, interface, long, native, new, package, private, protected, public, return, short, static, strictfp, super, switch, synchronized, this, throw, throws, transient, try, void, volatile, while

Python：False, None, True, and, as, assert, async, awAIt, break, class, continue, def, del, elif, else, except, finally, for, from, global, if, import, in, is, lambda, nonlocal, not, or, pass, rAIse, return, try, while, with, yield

Java

JavaScript：break, case, catch, class, const, continue, debugger, default, delete, do, else, export, extends, false, finally, for, function, if, import, in, instanceof, new, null, return, super, switch, this, throw, true, try, typeof, var, void, while, with, yield

C：auto, break, case, char, const, continue, default, do, double, else, enum, extern, float, for, goto, if, inline, int, long, register, restrict, return, short, signed, sizeof, static, struct, switch, typedef, union, unsigned, void, volatile, while
