期末考试啊

1、    判断输入的数能否被3，5，7同时整除 

//1、	判断输入的数能否被3，5，7同时整除
package wf;

import java.util.Scanner;

public class test1 {

	@SuppressWarnings("resource")
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		System.out.println("输入一个整数");
		int a =scanner.nextInt();
		if (a%3==0 && a%5==0 && a%7==0) {
			System.out.println(a+"可以同时被3 5 7整除");
		}else {
			System.out.println("无法实现");
		}
	}
}

2. 输入学生的成绩，输出不同的等级成绩【<60 不及格，60~80：良好，>80：优秀】

package wf;

import java.util.Scanner;

public class test2 {
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		System.out.println("输入成绩");
		int a = scanner.nextInt();
//		switch (a/10) {
//		case 10 : case 9:case 8:
//			System.out.println("优秀");
//			
//			break;
//		case 6: case 7:
//			System.out.println("良好");
//			
//			break;
//		 case 5: case4:
//			System.out.println("不及格");
//			
//			break;
//		default:
//			System.out.println("成绩无效");
//			break;
//		}
		if(a<=100 && a>80) {
			System.out.println("优秀");
		}else if(a>=60 && a<=80){
			System.out.println("良好");
		}else if(a>=0 && a<60) {
			System.out.println("不及格");
		}else {
			System.out.println("数据不合法");
		}
	}
}

 3.打印九九乘法表

package wf;

public class test3 {
public static void main(String[] args) {
	for (int i = 1; i <10; i++) {
		for (int j = 1; j <= i; j++) {
			System.out.print(j+"*"+i+"="+i*j+" ");
		}
		System.out.println("");
	}
}	
}

4.从键盘输入一个百位数，计算并输出个位、十位、百位的数字之和

package wf;

import java.util.Scanner;

public class test4 {
 public static void main(String[] args) {
	    Scanner sc = new Scanner(System.in);
	    System.out.println("请输入一个百位数");
	    int k =sc.nextInt();
		int m = k%10;
		int n = k%100/10;
		int l = k/100;
		int a = m+ n +l;
	System.out.println("和为:" +a);

}
}

 5.用封装的思想定义Product类，包含id,name,price属性

package wf;

public class Product {
	
	private int id;
	private String name;
	private double price;
	public Product() {
		super();
		// TODO Auto-generated constructor stub
	}
	
	public Product(int id, String name, double price) {
		super();
		this.id = id;
		this.name = name;
		this.price = price;
		
	}

	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public double getPrice() {
		return price;
	}
	public void setPrice(double price) {
		this.price = price;
	}
	@Override
	public String toString() {
		return "test7 [id=" + id + ", name=" + name + ", price=" + price + "]";
	}	
}
