public static int cssjs(int a,int b) { Random rand=new Random(); int zhi; zhi=rand.nextInt(b)%(b-a+1)+a; return zhi; } 我们观察其Random对象的nextInt(int)方法,发现这个发现这个方法将生成 0 ~ 参数之间随机取值的整数.例如(假设先有 Random rand = new Random();rand.nextInt(100);这行代码将生成范围 0~100 之间的

Java中实现十进制数转换为二进制 第一种:除基倒取余法 这是最符合我们平时的数学逻辑思维的,即输入一个十进制数n,每次用n除以2,把余数记下来,再用商去除以2...依次循环,直到商为0结束,把余数倒着依次排列,就构成了转换后的二进制数.那么,在实际实现中,可以用int的一个数来存储最后的二进制,每次求余后把余数存储在int型数的低位,依次递增. 1 public void binaryToDecimal(int n){ 2 int t = 0; //用来记录位数 3 int bin = 0;
