定义榨汁机JuiceMachine 有榨汁方法makeJuice传入相应的水果。如果传入的是Apple 输出 流出苹果汁传入的是Orange 输出 流出橙汁传入的是Banana 输出 流出香蕉酱java实现

public class JuiceMachine { public void makeJuice(String fruit) { if (fruit.equals("Apple")) { System.out.println("流出苹果汁"); } else if (fruit.equals("Orange")) { System.out.println("流出橙汁"); } else if (fruit.equals("Banana")) { System.out.println("流出香蕉酱"); } }

public static void main(String[] args) { JuiceMachine machine = new JuiceMachine(); machine.makeJuice("Apple"); machine.makeJuice("Orange"); machine.makeJuice("Banana"); }
