JAVA抽签小程序
您好：package test;import java.util.HashSet;
import java.util.Set;
import java.util.Iterator;public class test {
public static void main(String[] args) {
Set set = new HashSet();
for (int i = 1; i = 100; i++) {
set.add(i);
}
Iterator it = set.iterator();
for (int i = 0; i set.size(); i++) {
if(it.hasNext()){
System.out.println(it.next());
}
}
}
}先把100放入set然后再随即找出来。另外一个想法是随即产生数，放入list中判断是否重复，这样也达到这样的效果。
java小程序源代码，简单点的，100多行，谁有啊？？

求java经典小程序代码
代码如下：
public class HelloWorld {
public static void main(String []args) {
int a = 3, b = 7 ;
System.out.println("Hello World!");
}
public static int f(int a, int b){
return a*a + a*b + b*b;
}
}
结果如下：
