你也可以用if-then-else Statement 代替 switch Statement。 决定是使用if-then-else语句还是switch语句取决于可读性和语句测试的表达式。if-then-else语句可以基于值或条件的范围测试表达式,而switch语句仅基于单个整数、枚举值或String对象测试表达式。 在switch语句中,break语句时必须的,break语句用于终止并且闭合switch语...
We can execute multiple-line control flow statements using JShell the same as Java. The control flow statements like If-else statement, for-loop and while-loop can also be executed in JShell. It recognizes multiple-line statements are prompts with the symbol “…>” to indicate to enter the...
In a given block, the program is executed sequentially one statement at a time starting from the first statement at the top and proceeding toward the bottom. This scheme, without any additional flow logic, will execute each statement precisely once. However, if a programming language is to ...
