在Java 中,三元运算符(Ternary Operator) 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

The first operand in java ternary operator should be a boolean or a statement with boolean result. If the first operand is true then java ternary operator returns second operand else it returns third operand. Syntax of java ternary operator is: result = testStatement ? value1 : value2; If ...
2. 案例演示 TernaryOperator.java 分析:b是先赋值再自减,所以result = 99;接着 b 再自减1为98 代码语言:javascript 代码运行次数:0 运行 AI代码解释 int a=10;int b=99;// 解读// 1. a > b 为 false// 2. 返回 b--, 先返回 b的值,然后在 b-1// 3. 返回的结果是99int result=a>b?a+...
Short Hand if...elseThere 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:...
When to use the Ternary Operator? In Java, the ternary operator can be used to replace certain types of if...else statements. For example, You can replace this code class Main { public static void main(String[] args) { // create a variable int number = 24; if(number > 0) { Syste...

另一个条件运算符是?:,可以被视为if-then-else语句的简写(在本课程的控制流语句部分讨论)。这个运算符也被称为三元运算符,因为它使用三个操作数。在下面的例子中,这个运算符应该被理解为:“如果someCondition为true,则将value1的值赋给result。否则,将value2的值赋给result。” 以下程序,ConditionalDemo2,测试了...
Ternary if-else operator boolean-exp ? value0 : value1 String operator + and += There's one special usage of an operator in Java: The + and += operators can be used to concatenate strings. The binary representation of the numbers is referred to as signed twos complement. ...
Java ternary operator is a conditional operator and can be used as a replacement for a simple if-else statement or a switch statement. Theternary operatoris aconditional operatorand can be used as a replacement for using a simpleif-else statement. In some cases, we can use the ternary opera...
