Java: randomly select 5 random numbers in 100.

You have to work hard! This kind of program has to be asked. Please refer to this code! Read more jdk documents, many of which are well packaged.

Import java.util.hashset;

Common class test {

Public static void main (strinargs []) {

HashSet & lt integer & gths = new HashSet< Integer & gt ();

while (true) {

int a =(int)(math . random()* 100)；

If (a> =10&; & ampa & lt= 100) {

hs . add(a)；

}

if (hs.size() == 5) {

Break;

}

}

system . out . println(hs)；

}
