■》Conditional Statements ‘if-else’->

The if block is used to specify the code to be executed if the condition specified in if is true, the else block is executed otherwise.

■》Example->

int age =30;

if(age > 18) {

   System.out.println("This is an adult");

} else {

   System.out.println("This is not an adult");

}

■》Conditional Statements ‘switch'->

Switch case statements are a substitute for long if statements that compare a variable to multiple values. After a match is found, it executes the corresponding code of that value case.

The following example is to print days of the week:->

int n ;

switch(n) {

   case 1 :

       System.out.println("Monday");

       break;

   case 2 :

       System.out.println("Tuesday");

       break;

   case 3 :

       System.out.println("Wednesday");

       break;

   case 4 :

       System.out.println("Thursday");

       break;

   case 5:

       System.out.println("Friday");

       break;

   case 6 :

       System.out.println("Saturday");

       break;

   Case 7:

       System.out.println("Sunday");

       break;

   default :

           System.out.println(" invalid ");

}
