Time in Text - Java

I made a code that formats the typed time(numbers) into text. But the problem is when it's for example 10:30 he text should be "halb elf uhr" and not "halb zehn uhr" (language is german). So I think the case must be increased but how can I do this. I tried it with case+1 but that diddn't work.

This is the code:

public class TimeAsText {

    public static void main(String[] args) {
        System.out.println("Type Hour: ");
        int hours = In.readInt();
        System.out.println("Type minutes: ");
        int minutes = In.readInt();;

        if(hours <1 || hours >12) {
            System.out.println("*****");
            System.exit(0);

        }else if (minutes <0 || minutes >59) {
            System.out.println("****"); 
            System.exit(0);
        }else {
            String hourNames = null;
            switch(hours) {
                case 1: hourNames = "ein";break;
                case 2: hourNames = "zwei";break;
                case 3: hourNames = "drei";break;
                case 4: hourNames = "vier";break;
                case 5: hourNames = "fuenf";break;
                case 6: hourNames = "sechs";break;
                case 7: hourNames = "sieben";break;
                case 8: hourNames = "acht";break;
                case 9: hourNames = "neun";break;
                case 10: hourNames = "zehn";break;
                case 11: hourNames = "elf";break;
                case 12: hourNames = "zwoelf";break;
                default: System.out.println("Type valid hour");
            }
            String minuteNames = null;
            switch(minutes) {
                case 0: minuteNames = "punkt";break;
                case 1: minuteNames = "eines";break;

Try this.

System.out.println("Type Hour: ");
int hours = In.readInt();
System.out.println("Type minutes: ");
int minutes = In.readInt();
if (minutes == 30)
{
   hours++;
}

The problem is sometimes you want to use the name of hours+1. It is easiest to tackle such problems using the abstraction of several methods.

public static void main(String[] args) {
    System.out.println("Type Hour: ");
    int hours = In.readInt();
    System.out.println("Type minutes: ");
    int minutes = In.readInt();;
    if (hours < 1 || hours > 12) {
        System.out.println("*****");
        System.exit(0);

    } else if (minutes < 0 || minutes > 59) {
        System.out.println("****"); 
        System.exit(0);
    }
    System.println("Zeit: " + zeit(hours, minutes));
}

static String zeit(int hours, int minutes) {
    if (minutes == 0) {
        return hourName(hours) + " Uhr");
    } else if (minutes == 15) {
        return "Viertel nach " + hourName(hour) + " Uhr"); // Quarter past
        // Ex-DDR:
        //return "Viertel " + hourName(1 + (hour % 12)) + " Uhr"):
    } else if (minutes == 30) {
        int nextHour = hours + 1;
        if (nextHour > 12) {
            nextHour = 1;
        }
        return "Halb " + hourName(nextHour) + " Uhr");
    } else if (minutes == 45) {
        int nextHour = hours + 1;
        if (nextHour > 12) {
            nextHour = 1;
        }
        return "Viertel vor " + hourName(nextHour) + " Uhr");
    } else {
        return hourName(hours) + " Uhr " + minuteName(minutes));
    }
}

static String hourName(int hours) {
    String hourNames = null;
    switch(hours) {
    case 1: hourNames = "ein";break;

    case 12: hourNames = "zw\u00F6lf";break;
    default: System.out.println("Type valid hour");
    }
    return hourNames;
}

static String minuteName(int minutes) {
    String minuteNames = null;
    switch(minutes) {
    case 0: minuteNames = "punkt";break;
    case 1: minuteNames = "eines";break;

    case 49: minuteNames = "neunundvierzig";break;
    case 50: minuteNames = "fuenfzig";break;
    case 51: minuteNames = "einundfuenfzig";break;
    case 52: minuteNames = "zwweiundfuenfzig";break;
    case 53: minuteNames = "dreiundfuenfzig";break;
    case 54: minuteNames = "vierundfuenfzig";break;
    case 55: minuteNames = "fuenfundfuenfzig";break;
    case 56: minuteNames = "sechsundfuenfzig";break;
    case 57: minuteNames = "siebenundfuenfzig";break;
    case 58: minuteNames = "achttundfuenfzig";break;
    case 59: minuteNames = "neunundfuenfzig";break;
    default: minuteNames = "Type valid nummer";break;
    }
    return minuteNames;
}

If you already know the modulo operator %: 

    int nextHour = 1 + (hours % 12);

I think you have to do some Object Oriented programming. I would create an interface WordFormat with a method like 

public String format(int hours, int minutes)

and a concrete class that hods your implementation.

then you can create other concrete class that translate in a different way following certain rules (if minutes are 30 then return else null).

at the end a class that allows you a logic like: given the ordered WordFormat, try to apply the first, if it fails (return null in my example) apply the second and so on until your last, default format...
