public AbstractParent() {
System.out.println("Hello,parent");

protected void earnMoney() {
prepare();
doJob();
}

protected abstract void doJob();

private void prepare() {
System.out.println("parent prepare");

class Child extends AbstractParent {
public Child() {
System.out.println("Child init");
}

@Override
protected void doJob() {
