IF Else If Statement

Nested if Statement :-

• The nested if statement is if statement inside the if statement.
• Example:-

int a = 25;
if (a > 0){
   if(a > 16){
      System.out.println("Welcome");
   }else{
      System.out.println("Too young");
   }
}else{
   System.out.println("Error");
}

If..else if statement:-

• Instead of using nested if statement , we can use the else if statement to check multiple condition.
• Example:-

int a = 25;
if (a > 0){
      System.out.println("Error");
}else if(a <= 16){
      System.out.println("Too young");
}else if(a < 100){
      System.out.println("Welcome !");
}else{
      System.out.println("Really ?");
}
