在Java 中,三元运算符(Ternary Operator) 是一种简洁的条件表达式,用于替代简单的 if-else 语句。它的语法如下: java 条件? 表达式1 : 表达式2; 执行逻辑:如果条件为 true,则返回 表达式1 的值;否则返回 表达式2 的值。 特点:单行完成条件判断,适合简单的分支逻辑。 1. 基本用法示例 判断奇偶性 java
In short, It improves code readability. 2. Null Check It’s common to use the ternary operator as null check. JavaExample2.java packagecom.mkyong.test;importcom.mkyong.customer.model.Customer;publicclassJavaExample2{publicstaticvoidmain(String[] args){Customerobj=null;intage=obj !=null? obj.g...
Example: Java Ternary Operator import java.util.Scanner; class Main { public static void main(String[] args) { // take input from users Scanner input = new Scanner(System.in); System.out.println("Enter your marks: "); double marks = input.nextDouble(); // ternary operator checks if /...

This will let you see the result of your ternary operator in the Java console. Unlike an “if” statement, the ternary operator does not accept an “else” keyword. The ternary statement uses the colon (:) to represent an “else” condition. Let’s use an example to show this operator...
