}

編寫java程序，由鍵盤輸入年份，顯示當(dāng)年日歷，要求使用數(shù)組。

首先鍵盤輸入的話多種方式實(shí)現(xiàn)，提供兩種，一是使用main方法的arg參數(shù)，也就是在使用java命令的時(shí)候后面跟上參數(shù)，在main方法里調(diào)用arg[0]即可，第二種方法是使用scanner類來得到system.in的內(nèi)容

然后就是打印全年，這個(gè)只要使用calendar類即可，得到calendar對象以后通過一個(gè)循環(huán)365次，不斷的day加一即可

求一個(gè)JAVA編寫的日歷，用控制臺的形式顯示。
