006-Switch Case

This video explains how one can use switch..case in Java. First it shows the how you can form a simple switch statement then tells the importance of a break statement.

Next, you see the need for case default. The video ends up with combining multiple case matches with a single body.

import java.util.Scanner;

//Example 01: Nested If Statements
public class Example
{
public static void main(String[] args)
{
//Get input from the user
int x;
System.out.println("Enter any integer between 1..20");
Scanner scn = new Scanner(System.in);
x = scn.nextInt();

//Use switch case
switch(x)
{
case 5:
System.out.println("The Number is 5");
break;
case 10:
System.out.println("The Number is 10");
break;
case 15:
System.out.println("The Number is 10");
break;
}
}
}

//Example 02: Switch..case with default
public class Example
{
public static void main(String[] args)
{
//Get input from the user
int x;
System.out.println("Enter any integer between 1..5");
Scanner scn = new Scanner(System.in);
x = scn.nextInt();

//Use switch case
switch(x)
{
case 1:
System.out.println("One");
break;
case 2:
System.out.println("Two");
break;
case 3:
System.out.println("Three");
break;
case 4:
System.out.println("Four");
break;
case 5:
System.out.println("Five");
break;
default:
System.out.println("Number not in Range");

}
}
}
