Java程序，100行左右，需要运行成果图。 程序随便。 2个有追加
200多行，程序功能是输入两个数字的英文单词（20以内），输出结果，这个结果也是一个英文(就是将结果转换成英文输出)

java程序：编写生成100个1-6之间的随机数，统计1—6每个出现的概率，菜鸟看不懂程序
1.用内置方法Math.random()产生一个随机数介于0～1。
2.强制转化为int类型，根据int类型的特点，这个数是0～5之间的整数。
3.得到的数加1，这样这个数就是介于1～6的整数，并且是随机的。
4.将介于1～6之间的这个整数赋值给randomNum
5.（重点）probability是个数组，这个程序的算法就是：利用probability这个数组记录随机数出现的次数，probability[0]记录随机数1出现的次数，就是当出现的随机数为1时，数组的probability[randomNum-1]项加1（randomNum-1是为了表现算法，实际的程序中是不需要先加1再减1的）。同理：其它的随意数也做这样的处理。这样，probability这个数组中[0]项保存的是1的出现次数，[1]项保存的是2出现的次数…………
6.输出随机数的值（后面加个空格“\t”）
7.循环到步骤第1.个步骤.
