What is if-else in Java?
In Java, if-else is a control flow statement that allows you to execute different blocks of code based on certain conditions. It helps your program make decisions by checking a condition and then performing specific actions depending on whether that condition is true or false.

if statement: This is used to test a condition. If the condition evaluates to true, the block of code inside the if statement runs.

else statement: This provides an alternative block of code that will run if the condition in the if statement is false.

Basic if-else Syntax:

Copy code
if (condition) {
// Code to execute if the condition is true
} else {
// Code to execute if the condition is false
}

What is a Nested if in Java?
A nested if statement is when you place one if or if-else statement inside another if or else block. It allows you to check multiple conditions in a sequence, where one condition depends on another.

Nested if Syntax:

Copy code
if (condition1) {
if (condition2) {
// Code to execute if both condition1 and condition2 are true
}
}

The else if Ladder:
Sometimes, you may want to test multiple conditions. In such cases, the else if ladder is used. It allows you to check multiple conditions sequentially.

else if Syntax:

Copy code
if (condition1) {
// Code to execute if condition1 is true
} else if (condition2) {
// Code to execute if condition1 is false and condition2 is true
} else {
// Code to execute if all previous conditions are false
}


Summary:
if checks a condition and runs code if it’s true.
else provides an alternative action if the if condition is false.
Nested if is used for more complex decision-making, with conditions within conditions.

else if allows you to check multiple conditions in a sequence.
This is a crucial concept in controlling the flow of logic in Java programs!
