The if...else statement is used in Java (and many other programming languages) to provide a way for a program to make decisions and choose between different actions based on certain conditions.
The basic syntax of the if...else statement in Java is:
if (condition) {
// code to execute if condition is true
} else {
// code to execute if condition is false
}
The condition can be any expression that evaluates to a boolean value (true or false). If the condition is true, then the code inside the first set of curly braces will be executed. If the condition is false, then the code inside the second set of curly braces (the else block) will be executed instead.
The if...else statement can also be extended to include additional conditions using the else if keyword, like this:
if (condition1) {
// code to execute if condition1 is true
} else if (condition2) {
// code to execute if condition2 is true
} else {
// code to execute if all conditions are false
}
In this case, if condition1 is true, its corresponding code block will be executed. If it is false, but condition2 is true, its corresponding code block will be executed instead. If both conditions are false, then the else block will be executed.
