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...

它们允许我们根据条件执行不同的代码块。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...

Spring EL supports ternary operator , perform “if then else” conditional checking. For example, condition?true:false Spring EL in Annotation Spring EL ternary operator with@Valueannotation. In this example, if “itemBean.qtyOnHand” is less than100, then set “customerBean.warning” to true,...
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, and is often used to replace simple if else statements: ...
