Array or ArrayList ?

My opinion is, you should first go to the youtube and check sum tutorials about arrays and arrayList and check below sample code

public class GeneralFine {

private int genFeeId;

private String genFeeDescription;

private double genFeeAmount;

public int getGenFeeId() {

return genFeeId;

}

public void setGenFeeId(int genFeeId) {

this.genFeeId = genFeeId;

}

public String getGenFeeDescription() {

return genFeeDescription;

}

public void setGenFeeDescription(String genFeeDescription) {

this.genFeeDescription = genFeeDescription;

}

public double getGenFeeAmount() {

return genFeeAmount;

}

public void setGenFeeAmount(double genFeeAmount) {

this.genFeeAmount = genFeeAmount;

}

@Override

public String toString() {

return "GeneralFine [genFeeId=" + genFeeId + ", genFeeDescription=" + genFeeDescription + ", genFeeAmount="

+ genFeeAmount + "]";

}

}

---------------------------------------------------------------------------------------------------------------------------------------------------------------

public static void main(String[] args) throws InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {

List<GeneralFine> genList = new ArrayList<>();

//Adding 10 objects of GenealFine Class to ArrayList genList

for (int i = 1; i <= 10; i++) {

GeneralFine objGF = new GeneralFine();

objGF.setGenFeeId(i);

objGF.setGenFeeDescription("Description "+i);

objGF.setGenFeeAmount(200);

genList.add(objGF);

}

Iterator<GeneralFine> objIterator = genList.iterator();

while(objIterator.hasNext()) {

System.out.println(objIterator.next().toString());

}

}
