In if-else construct which part will be executed if condition is ture in Java ?

In an if-else construct in Java, the code within the if block will be executed if the condition specified in the if statement is true. If the if condition is false, then the code within the else block (if an else block is provided) will be executed.

Here's the general syntax of an if-else construct:
if (condition) {
// Code to execute if the condition is true
} else {
// Code to execute if the condition is false
}

So, if the condition within the parentheses after if is true, the code in the if block will be executed. If the condition is false, the code in the else block (if present) will be executed.

Here's an example:
int age = 20;
if (age >= 18) {
System.out.println("You are an adult.");
} else {
System.out.println("You are not an adult.");
}

In this example, if the age is greater than or equal to 18, the message "You are an adult" will be printed because the condition is true. If the age is less than 18, the message "You are not an adult" will be printed because the condition is false, and the code in the else block will be executed.
