Hier mein Programm der Prüfung der Gruppe C:
Es war ein Programm zu erstellen welches werte aus einer anderen Datei einliest, min und max bestimmt, die Werte sortiert und in einer anderen Datei wieder ausgibt.
import java.io.*;
import java.util.Scanner;
import java.util.Locale;
public class YourName
{
public static void main (String[] args) /*method reads data, needs file name */
{

float[] data1= new float[6];
float minimum=0;
float maximum=0;
data= read(inpFile); //String for read operation as parameter
data1=data;
minimum=min(data); //
maximum=max(data);
System.out.println("Minimum "+minimum);
System.out.println("Maximum "+maximum);
write(outFile, data1, maximum, minimum);
//System.out.println("daten"+data[0]);
}

i=i+1;
}
sc.close();
}
catch (Exception e) /*catch error which may occurs, catches all possible acceptions*/
{
System.out.println("Error reading file ");
System.exit(1); /*close program*/
}
