Question

JAVA怎么做这道题？

刚上一个月课，最好附一下代码的意思，上课没怎么听。。。

Answer 1

代码如下：

class Fruit {
	
	private String kind;
	
	private int number;
	
	private float price;

	public Fruit(String kind, int number, float price) {
		this.kind = kind;
		this.number = number;
		this.price = price;
	}

	public String getKind() {
		return kind;
	}

	public void setKind(String kind) {
		this.kind = kind;
	}

	public int getNumber() {
		return number;
	}

	public void setNumber(int number) {
		this.number = number;
	}

	public float getPrice() {
		return price;
	}

	public void setPrice(float price) {
		this.price = price;
	}
	
	public void print() {
		System.out.println(this.kind + "\t" + this.number + "\t" + this.price);
	}
}

public class App73 {

	public static void main(String[] args) {
		
		Fruit fruit1 = new Fruit("苹果", 10, 12.0f);
		Fruit fruit2 = new Fruit("生梨", 20, 5.0f);
		Fruit fruit3 = new Fruit("香蕉", 30, 8.0f);
		
		System.out.println("水果名称" + "\t" + "水果数量" + "\t" + "水果价格");
		fruit1.print();
		fruit2.print();
		fruit3.print();
	}
}

运行结果：

Answer 2

public class Fruit {
private String kind;
private int number;
private int price;
public String getKind() {
return kind;
}
public void setKind(String kind) {
this.kind = kind;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
public Fruit(String kind, int number, int price) {
super();
this.kind = kind;
this.number = number;
this.price = price;
}
public Fruit(){

}
}
public class Main {
public static void main(String[] args) {
Fruit fruit = new Fruit("fds", 1, 2);
Fruit fruit2 = new Fruit("fds", 1, 2);
Fruit fruit3 = new Fruit("fds", 1, 2);
System.out.println("水果名称"+"\t"+"水果数量"+"\t"+"水果价格");
System.out.println(fruit.getKind()+"\t"+fruit.getNumber()+"\t"+fruit.getPrice());
System.out.println(fruit2.getKind()+"\t"+fruit2.getNumber()+"\t"+fruit2.getPrice());
System.out.println(fruit3.getKind()+"\t"+fruit3.getNumber()+"\t"+fruit3.getPrice());

}
}
