Overview

Java if-else is a control structure and is used to make decisions based on conditions. We can use this statement to branch out code based on branch conditions.

Java if-else statement

If the given condition is True the program executes one path, and if the condition is false the program takes another path.

Let’s see a simple example, below a sample piece of  Java code:

public class JavaIFExample 
{
  
  public static void main(String[] args)
   {
    
    int dummyVariable = 70 ;
    
    if(dummyVariable > 100)
    { 
      System.out.println("dummyVariable > 100 ");
    } 
    else 
    { 
      System.out.println("dummyVariable < 100 "); }
   	           
   }

}

 

Output of the Program

dummyVariable < 100

 

 

The program output depends on what the if condition evaluates to True or False. The program executes the code depending on the value of dummyVariable in the above program.
