java初学者，求大神指教：数组和方法的使用2

1.定义数组,存储1-100(包括1和100)之间所有能被7整除的数字
2.定义方法,传递数组,计算数组元素最大值并将结果返回
3.定义方法,传递数组,计算数组元素最小值并将结果返回
3.定义方法,传递数组及最大值,最小值,将最大值和最小值进行交换,并打印交换后的数组*/

Answer 1

public class good {
private String name;
private String number;
private String type;
private Double price;
private String describe;

public good(String name, String number, String type, Double price,
String describe) {
super();
this.name = name;
this.number = number;
this.type = type;
this.price = price;
this.describe = describe;
}

public good() {
super();
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getNumber() {
return number;
}

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

public String getType() {
return type;
}

public void setType(String type) {
this.type = type;
}

public Double getPrice() {
return price;
}

public void setPrice(Double price) {
this.price = price;
}

public String getDescribe() {
return describe;
}

public void setDescribe(String describe) {
this.describe = describe;
}
}
然后拿着商品对象操作就行了，如果需要在控制台打印还要重写toString()方法
