在UML类图中，您可以看到从Account类中延伸出两个箭头。这两个箭头的含义是，您的SavingsAccount和CheckingAccount类是从Account父类继承而来的。因此，您必须借助Java中的extends关键字来实现这两个子类。
示例框架：
public class Account{
//成员变量和方法
}
public class SavingsAccount extends Account{
//成员变量和方法
}
public class CheckingAccount extends Account {
//成员变量和方法
}

英文:
So in the UML class diagram you can see there are two arrows going out from the Account class. Meaning of those two arrows are your SavingsAccount and CheckingAccount classes are inheriting from the Account parent class.So you must implement those two child classes with the aid of extends keyword in Java.
Please refer this tutorial for a complete understanding
Sample skeleton:
public class Account{
//member variables and methods
}
public class SavingsAccount extends Account{
//member variables and methods
}
public class CheckingAccount extends Account {
//member variables and methods
}
