testexcise0209.java

我在学习JAVA的讲义

import  java.io.*;                          
 class	 Excise0209{
	int x;
	public void setX(int a){
		x=a;
	}
	public boolean judge(){
		if (x%2==0 && x%3==0 && x%5==0)
			return true;
		return false;
	}
}

public class TestExcise0209{
	public static void main(String[] args){
		Reader ir = new InputStreamReader(System.in);
		BufferedReader r = new BufferedReader(ir);
		String sc="";
		int intA=0;
		try{
			sc = r.readLine();
		}catch (IOException e){}
		try{
			intA=Integer.parseInt(sc);
		}catch (NumberFormatException e){
			System.out.println("输入的数据不是整数");
		}
		Excise0209 b = new Excise0209();
		b.setX(intA);
		if (b.judge()){
			System.out.println("能同时被2、3、5整数");
		}
		else 
			System.out.println("不能同时被2、3、5整数");
	}
