Java has the following conditional statements: Use the if statement to specify a block of Java code to be executed if a condition is true. Note that if is in lowercase letters. Uppercase letters (If or IF) will generate an error. In the example below, we test two values to find out if 20 is greater than 18.

Apr 16, 2025 · The if-else statement in Java is a powerful decision-making tool used to control the program's flow based on conditions. It executes one block of code if a condition is true and another block if the condition is false. In this article, we will learn Java if-else statement with examples. Example: [GF

Nov 22, 2024 · The Java if statement is the most simple decision-making statement. It is used to decide whether a certain statement or block of statements will be executed or not i.e. if a certain condition is true then a block of statements is executed otherwise not.

Nov 29, 2022 · In this tutorial, you used conditional statements to direct the execution flow. You learned when it is suitable to use if and switch statements and wrote a few code examples with them. You also learned best practices for clean code and how to avoid common pitfalls related to conditionals. For more on Java, check out our How To Code in Java series.

You could use an if-then-else statement in the applyBrakes method to take some action if the brakes are applied when the bicycle is not in motion. In this case, the action is to simply print an error message stating that the bicycle has already stopped.

Sep 11, 2022 · In this tutorial, we will see four types of control statements that you can use in java programs based on the requirement: In this tutorial we will cover following conditional statements: If statement consists a condition, followed by statement or a set of statements as shown below:

The Java if...else statement is used to run a block of code under a certain condition and another block of code under another condition. In this tutorial, we will learn about if...else statements in Java with the help of examples.

The if statement is an absolute must-know in Java if you want to create programs that don't always perform the exact same routine over and over again. Programs are always executed from top to bottom. That is just how they work.

In this lesson we take our first look at the conditional statements available in Java. Conditional statements allow us to evaluate an expression and execute some code dependant upon the outcome. There are two conditional statements we can use with Java, the if Construct covered here and the switch Construct which we will cover in the next lesson.

Feb 11, 2025 · In this blog post, we shall introduce you to the conditional statements in the Java programming language, along with their syntaxes, flowcharts, and examples. The Java programming language provides five different conditional statements, namely if, if-else, if-else-if, nested if, and switch case.
