Strings assign with scanner
I have 4 Strings and i need to assign them. If there is no next line a exception for eachstring should be thrown. Can i do that anyhow with a loop instead of 4 if else statements?

You could store your strings as an array:
String[] strings = new String[4];
Scanner sc = new Scanner(/* ... */);
int index = 0;
while (sc.hasNext()) {
if (index >= strings.length) break;
strings[index] = sc.next();
index++;
}
// beware:
// if this loop terminates because hasNext is false, the remaining strings will be null
// Access strings as you normally would access an array
String firstString = strings[0];
// ... and such
