如何在创建多个类似的jbutton时防止重复

Question

我正在尝试学习java GUI，但我似乎注意到在尝试创建多个类似按钮时存在大量重复。例如在这段代码中：

JButton btnAddCar = new JButton("Add Car");
btnAddCar.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddCar.setBounds(5, 5, 355, 155);
addInternalFrame.getContentPane().add(btnAddCar);

JButton btnAddHybridCar = new JButton("Add Hybrid Car");
btnAddHybridCar.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddHybridCar.setBounds(5, 165, 355, 155);
addInternalFrame.getContentPane().add(btnAddHybridCar);

JButton btnAddVan = new JButton("Add Van");
btnAddVan.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddVan.setBounds(5, 325, 355, 155);
addInternalFrame.getContentPane().add(btnAddVan);

JButton btnAddMotorcycle = new JButton("Add Motorcycle");
btnAddMotorcycle.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddMotorcycle.setBounds(5, 485, 355, 155);
addInternalFrame.getContentPane().add(btnAddMotorcycle);

JButton btnAddHybridMotorcycle = new JButton("Add Hybrid Motorcycle");
btnAddHybridMotorcycle.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddHybridMotorcycle.setBounds(5, 645, 355, 155);
addInternalFrame.getContentPane().add(btnAddHybridMotorcycle);

JButton btnAddCustomer = new JButton("Add Customer");
btnAddCustomer.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddCustomer.setBounds(365, 5, 355, 155);
addInternalFrame.getContentPane().add(btnAddCustomer);

JButton btnAddVIPCustomer = new JButton("Add VIP Customer");
btnAddVIPCustomer.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddVIPCustomer.setBounds(365, 165, 355, 155);
addInternalFrame.getContentPane().add(btnAddVIPCustomer);

JButton btnAddEmployee = new JButton("Add Employee");
btnAddEmployee.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddEmployee.setBounds(365, 325, 355, 155);
addInternalFrame.getContentPane().add(btnAddEmployee);

JButton btnAddDepartmentManager = new JButton("Add Department Manager");
btnAddDepartmentManager.setFont(new Font("Tahoma", Font.PLAIN, 20));
btnAddDepartmentManager.setBounds(365, 485, 355, 155);
addInternalFrame.getContentPane().add(btnAddDepartmentManager);

有没有一种更短、更美观的方式来编写这段代码？

Answer 1

您可以尝试将按钮创建外包到这样的方法中

注意：您可能还必须添加addInternalFrame作为参数

private JButton createButton(String name, int x, int y){
      JButton button = new JButton(name);
      button.setFont(new Font("Tahoma", Font.PLAIN, 20));
      button.setBounds(x, y, 355, 155);
      addInternalFrame.getContentPane().add(button);
      return button;
    }

并用它创建您的按钮

JButton btnAddCar = createButton("Add Car", 5, 5);
JButton btnAddHybridCar = createButton("Add Hybrid Car", 5, 165);
