Question

生成一个int数组,长度为100,其中随机插入1-100,并不重复

请大家帮忙解决下!

Answer 1

import java.util.Random;

public class testRandom
{
public static void main(String[] args)
{
Random test = new Random();
int[] a = new int[100];
int index;
for(index=0; index<a.length; index++){
a[index]=index+1;
}
index--;
int tempIndex, tempContent;
for(; index>=0; index--){
tempIndex = test.nextInt(a.length);
tempContent = a[index];
a[index] = a[tempIndex];
a[tempIndex] = tempContent;
}

for(int i=0; i< a.length; i++){
if((i%10)==0){
System.out.print("\n\n");
}
System.out.print(a[i]+" ");
}
}
}

也不说一下什么大没裤语言...就用JAVA吧...和C也比滚简较像察带
