The program tries to read a text file named modela which conatins characteristics of several cars . it also tries to put the values of the txt in the class Autokinhta , for example the value "106" in the line HORSEPOWER must be set as the value in setIppodunamh in the class Autokinhta. Here i have 2 problems .
1st I need the arithmetic values to be setted as in , double , float in each case , but for some reason they are not converted correctly from Striing to float , double , int .
Κυβισμος:6 ( LITTERS)
Ιπποδυναμη:0(HORSEPOWER)
Αριθμος Ταχυτητων:0( NUMBER_OF_GEARS)
Τυπος Κιβωτιου:5 ταχυτητων
Πλατος:0.0(WIDTH)
Μηκος:1.26
Υψος:1.45
Αριθμος θυρων:4
Τιμη:35000.0
2nd WHen i try to print the arraylist Ama3ia which contains all the car objects , i ony manage to print the last car Honda civic for 50 times .
[

Reason for edit:: Your problem is not printing the ArrayList, it is parsing the file to create the objects put into the ArrayList
