How to write an if else statement in java

We hope you find this tutorial helpful. In addition to guides like this one, we provide simple cloud infrastructure for developers. With conditional statements, we can have code that sometimes runs and at other times does not run, depending on the conditions of the program at that time.

How to write an if else statement in java

Use of this Decide if or else Many times, we need to see a condition and then decide what to do according to the condition.

For example, if it is raining, we will take an umbrella, otherwise not. Similarly, if a number is divisible by 2, it is even, otherwise it is odd. This is what if and else does in Java. So, it means that now you can take input from a user and perform according to it using if If it is raining, a person will take an umbrella.

This type of decision taking is done using if statement in Java. Let's have a look at the syntax of if statement before looking at its example.

Else block is optional

Here is a basic example of a block of code that contains an if statement, multiple else if statements, and an else statement in case none of the conditions evaluated to true. Java Decision Making Statements - If-Else, Switch, and Break Control flow statements in Java are divided in two parts: Decision Making and Iteration.

In this tutorial decision making (if-else, switch, and break) statements will be discussed. If-else and switch statements easily account for some of the ugliest code that I have seen (and written).

Overuse of if-else blocks can lead to the arrow antipattern, a scenario where conditional branches are so deeply nested they become unmaintainable. if-else statement in java. Advertisements.
