然而,如果不加以控制,过多的if-else语句可能会使代码变得混乱和难以维护。例如,当有多个嵌套的if-else语句时,代码的逻辑会变得复杂,阅读和理解起来也更加困难。 三元运算符的简洁性 为了减少if-else语句的使用并提高代码的可读性,我们可以使用三元运算符(ternaryoperator)。三元运算符允许在一行代码中根据条件进行简洁...
I thought that the ternary operator was just a more compact way of writing an if/else statement. But when I substitute the ternary operator in the code above with an if/else statement (currently commented out in code), the code doesn't work. I've probably got something wrong but I can...
步骤1:判断条件是否是等值比较 如果条件只是简单的等值比较,可以使用Java的三元运算符(ternary operator)来简化if-else语句。三元运算符的语法如下: variable = (condition) ? expressionTrue : expressionFalse; 1. 其中,condition是一个布尔表达式,如果为true,就返回expressionTrue的值;如果为false,就返回expressionFalse...
函数/方法提取: 把 if-else 内部具有独立功能的代码块封装成单独的函数或方法,减少嵌套并提升代码复用...
I'm trying to convert an if-else statement to an equal statement using the ternary operator ?-: My goal is to convert this code: if (s instanceof Class1) { do_something((Class1) s); } else if (s instanceof Class2) { do_something_else((Class2) s); } else { do_that((Class...
private int similarityCount (String one, String two) { if (one == null && two == null) { return 1; } else if (one == null && two != null) { return 2; } else if (one != null && two == null) { return 3; } else { if(isMatch(one, two)) return 4; return 5; } }...
functionoldYoung(age){if(age<16)return"children"elseif(age<50)return"young man"//use "else if" if neededelsereturn"old man"} This function returns a different value depending on the parameter age. Looks very complicated? Well, JS and Ruby also support theternary operatorand Python has some...
There is also a short-hand if else, which is known as theternary operatorbecause it consists of three operands. It can be used to replace multiple lines of code with a single line. It is often used to replace simple if else statements: ...
def minimum(x, y): return x or (x if x < y else y) The same error is generated if I replace the bolloean operatororwithand. Below is the whole transcript of my little session: python -c 'import testcase' && uncompyle6 testcase.pyc # Python 2.7 (decompiled from Python 2.7) #...
