In this example, the output would be “User is 18 or younger.” The point is that no matter what the user’s age is, the program will react and output a string value either way. You can learn more about using If statements in theIntroduction to Java Training Course. This can also be...
Java - Nested If statements I don’t know what I’m doing wrong. The prompt says to return “Gift Card” after multiple inputs. import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner read = new Scanner(System.in); int purchases = read.nextInt...
[ELSE statements;] END IF; 1. 2. 3. 4. 5. (4) IF嵌套 二、CASE条件控制语句 CASE条件控制语句可以分为两种类型: 1)一种是简单的CASE语句。它给出一个表达式,并把表达式结果同提供的几个可以预见的结果做比较,如果比较成功则执行对应的语句序列。
Using if-else Statements The if-else approach is a straightforward method to check if a string is null or empty in Java. It involves using conditional statements to evaluate the string and perform appropriate actions based on the result. Here’s how the basic if-else approach works: Firstly,...
Java has the following conditional statements:Use if to specify a block of code to be executed, if a specified condition is true Use else to specify a block of code to be executed, if the same condition is false Use else if to specify a new condition to test, if the first condition ...
In computer programming, we use the if statement to run a block of code only when a specific condition is met. In this tutorial, we will learn about Python if...else statements with the help of examples.
