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: a) if statement b) nested if statement c) if-else statement d) if-else-if statement If statement If ...
The Java if statement enables your Java programs to make decisions about what code to execute depending on the state of variables, or values returned from methods. Here is a simple Java if example: boolean isValid = true; if ( isValid ) { System.out.println("it is valid"); } else ...

statements can be used in combination with other control structures like loops or function calls. this allows you to create more sophisticated programs that adapt to different scenarios based on various conditions. can i use "else if" statements to check multiple conditions simultaneously? yes, you...
The if-else statement allows Java programs to handle both true and false conditions. If the condition inside the if statement evaluates to false, the else block is executed instead.Using if-else statements in Java improves decision-making in programs by executing different code paths based on ...

When you first begin programming in Java, most of your programs are sequential, or linear. This means that the code is executed from the top to the bottom and every single line of code is read. As your programs become more advanced, you will not always want the flow of execution to be...
Failing to handle null or empty strings appropriately can lead to unexpected errors and undesired behavior in your Java programs. Therefore, it is crucial to have a reliable method to determine whether a string is null or empty before performing any further operations on it. Using if-else ...
