How to put switches into loops?
I wonder how i could recounter the day when n is larger than 7? import java.util.Scanner; class Mozer{ public static void main(String [] args){ Scanner day = new Scanner (System.in); System.out.println("Enter a number:"); int n=day.nextInt(); while (n>0){ 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; } } } }

Inputs from 1-7
1 is Monday
7 is Sunday

Why the dislike? I mean he literally asked: "I wonder how I could recounter the day when n is larger than 7?"
I want an honest reply from the dislike

So you'll need to add the readInt() Inside the while loop.
And if the person enters the wrong integer try limiting it like:
if(input > 7){
input = 7;
}else
if(input < 1){
input = 0;
}
or
input = input%7 + 1;

There's really no point in having the switch inside the while loop in this case. Unless you really want to do your error checking with the default case.
It looks like what you really want is a do while loop for the input, so you can loop until you get a valid int and then to run the switch case.
import java.util.Scanner;
class Mozer{
public static void main(String [] args){
Scanner day = new Scanner (System.in);
int n;
do {
System.out.println("Enter a number:");
n=day.nextInt();
if (n < 1 || n > 7) {
System.out.println("Invalid input. Must be greater than 0 and less than 8.");
}
} while (n < 1 || n > 7);
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;
}
}
}
