The if-else Statement

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 conditions.

Syntax of if-else Statement

Following is the syntax of an if...else statement −

if(Boolean_expression) {     // Executes when the Boolean expression is true  }else {     // Executes when the Boolean expression is false  }  

If the boolean expression evaluates to true, then the if block of code will be executed, otherwise else block of code will be executed.
