如何将种子添加到伪数字发生器中？
我目前正在处理一项连续创建三个头部的作业，但我让它工作了，但我未能分配给我的测试人员，因为它说我的随机数生成器需要为此特定问题采用种子参数。我的代码是：
public static void threeHeads() {
Random r = new Random();
//int seed = r.nextInt();
int head =0;
while (head!=3) {
Boolean random = r.nextBoolean();
if(random==false) {
System.out.print("H");
head++;
}
else {
System.out.print("T");
head=0;
}
}
System.out.println("\nThree heads in a row!");
}
I am currently working on an assignment with creating three heads in a row and I got it working but I am failing the tester assigned to me because it's saying my random number generator needs to take a seed parameter for this particular problem. My code for this is :
public static void threeHeads() {
Random r = new Random();
//int seed = r.nextInt();
int head =0;
while (head!=3) {
Boolean random = r.nextBoolean();
if(random==false) {
System.out.print("H");
head++;
}
else {
System.out.print("T");
head=0;
}
}
System.out.println("\nThree heads in a row!");
}

随机构造函数用一种方法过载：
随机（长籽），它使您可以用预设种子实例化随机数生成器。The random constructor is overloaded with a method:
Random(long seed), which allows you to instantiate a random number generator with a preset seed.
