认识类-使用java.util.Scanner

import java.util.Scanner; //导入包，如果不导入要使用java.util.Scanner输出

public class exercise {

public static void main(String[] args) {
			
	Scanner sc = new Scanner(System.in);        //建立Scanner实例
	System.out.println("请输入6位数字密码：");
	
	int password =sc.nextInt();
	boolean result = (password == 123456);
	
	
	System.out.println("用户密码是否正确："+result);
	
	sc.close();
	
}

}
