Can any one expain how the following program works?

[itiger]

class SwitchTest
{
	public static void main(String args[])
	{
		int x = 5;
		switch(x)
		{
			case 1:
				System.out.println("In 1st case");
			return ;
			case 3:
				System.out.println("In 3rd case");
			return ;
			case 5:
				System.out.println("In 5th case");
			return ;
			case 7:
				System.out.println("In 7th case");
			return ;
			default:
				System.out.println("In default case");
		}
		System.out.println("Out of switch");
	}
}

Output:
In 5th case

What does return keyword returning here. Main() is not returning anything (void), So how the program is running without any error even though we are retuning something in switch.

You are returning in the switch statement. That is perfectly alright. Return statement returns the control to the caller. In this case with out any value.

In this program case 5 is matching value. So it prints and returns the control.

If you take x as 8 then the output will be

In default case
Out of switch

Why you are expecting any errors in this code?
