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
The first operand in java ternary operator should be a boolean or a statement with boolean result. If the first operand isthen java ternary operator returns second operand else it returns third operand. Syntax of java ternary operator is:If testStatement is true then value1 is assigned to resu...
Where can the ternary operator be used in programming? The ternary operator can be used in various programming contexts, such as assigning values to variables, determining the return value of a function, or specifying conditions in control flow statements. ...
The ternary operator is used to execute code based on the result of a binary condition. It takes in a binary condition as input, which makes it similar to an 'if-else' control flow block. It also, however, returns a value, behaving similar to a method.
#include<iostream>#include<string>usingnamespacestd;intmain(){intnumber =0;stringresult;// nested ternary operator to find whether// number is positive, negative, or zeroresult = (number ==0) ?"Zero": ((number >0) ?"Positive":"Negative");cout<<"Number is "<< result;return0; ...
The return type of bothtrueandfalseexpressions will be of a similar type which will be assigned to a variable as per the result. 1.2. Example In the following example, we are writing a statement using theif-elsestatement. Then we will rewrite the same statement using the ternary operator. ...
JAVA: import static java.lang.System.out; public class Ternary { public static void main(String[] args) { int a = 4, b = 5; out.println(++a == b-- ? a
There is also a short-hand if else, which is known as the ternary operator because it consists of three operands.It can be used to replace multiple lines of code with a single line, and is most often used to replace simple if else statements:...
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 /...
When using the ternary operator (conditional assignment) generics are not properly handled. This code gives an error import java.util.*; public class TestGenerics { public static void main(String[] args) throws Exception { boolean b = true; ...
